Wąska 13, Szczecin Słowa kluczowe: FISH, pojedyncze sekwencje powtarzalne (SSR), (AAC) 5, Secale. Key words: FISH, Secale, simple sequence repeats (SSRs), (AAC) 5. Abstract. The phylogenetic relationships of all species genus Secale have been interpreted from different types of data morphological, ecological, cytogenetic, and hybrid fertility assays. The phylogeny of genus was so far explained by checking the presence, structure, and chromosomal locations of a series of defined repeated sequences making up much of the heterochromatic regions of rye chromosomes (Bedbrook et all. 1980; Jones and Flavel 1982; Cuadrado and Jouve 1997). However, it was difficult to deduce evolutionary trends using only these sequences. The synthetic simple sequence repeats (SSRs) were proven to be useful as cytological markers for identifying chromosomes and for understanding genome organization in plants (Schmidt and Heslop-Harrison 1996, Cuadrado and Schwarzacher 1998; Fuchs et all. 1998; Cuadrado et all. 2000; Cuadrado and Jouve 2002), but SSRs have not been used extensively in phylogenetic studies in rye. In the present work the distribution on rye chromosomes simple sequence repeats (AAC) 5 was searched by FISH. These sequence was clustered mainly on the pericentric sites, only small signals were localized at the interstitial sites of the chromosome arm. Distribution of (ACC) 5 sequence repeats was specific for each species. Folia Univ. Agric.

Abstract. In years 2000 and 2001 experiments with 37 breeding lines of winter triticale were conducted. Triticale heads were inoculated with Fusarium culmorum. Head infection severity were scored and contents of trichothecenes of group B and ergosterol in grain were analysed. In 2000 head infection was 21.53%, and in %. Average deoxynivalenol content in 2000 was mg kg -1, and in mg kg -1. In 2000 average ergosterol concentration was mg kg -1, and in the next year mg kg -1. Coefficients of correlation between head infection and analysed metabolites were insignificant in 2000, and highly significant in For all analysed grain samples in both years significant correlation coefficient describing relation deoxynivalenol/ergosterol was found.

The average seed yield of the mixture of spring triticale and a 60-percent participation of field pea (4.40 t ha -1 ) was significantly higher than the yield of spring triticale and the yield of field pea seed cultivated in pure stand (by 0.19 and 0.25 t ha -1, respectively). The reduction of the share of spring triticale in the mixture increased plant lodging, yield and total protein content as well as the content of fibre and crude ash. Simultaneously, it reduced the content of crude fat and nitrogen free extract compounds in the seeds. The mixtures of spring triticale and field pea ( , , , %) cultivated for seeds yielded a significantly greater amount of total protein (from 75 to 362 kg ha -1 ) compared with the spring triticale cultivated in pure stand.

The aim of studies was the comparison of the quality of the made bread different methods. Technological parameters of five spring triticale cultivars (Gabo, Mieszko, Wanad, Kargo, Migo) from Plant Breeding Strzelce-Małyszyn from harvest 2001 and 2002 were tested. The following parameters were evaluated: yield of flour, colour, ash and protein content, SDS test, falling number, farinograph analysis and bread analysis. Flours from tested triticale cultivars did not show significant differences in the yield of flour, protein content and SDS test. Significant differences appeared in falling number and rheological properties of the dough. The bread from the flour of cultivars Gabo, Mieszko, Kargo was characterized with the similar crumb structure irrespective on used method of bread making. The bread from the flour of cultivars Wanad and Migo had the better crumb structure from the three-phase method. Folia Univ. Agric.

7 Abstract. There was showed that in Gabo spring triticale cultivation, grain and protein yield generally were depended on level and application method of nitrogen fertilization. The fertilizer level, application method and microelements addition were influenced on the production cost and the value of obtained protein yield. The total and true protein production cost was lower with higher nitrogen dose (120 kg ha -1 ) and foliar application but value of these was lower adequately about 0.42 and 0.37 and, about 0.14 and 0.13 zł kg -1. The nitrogen fertilization with dose 80 kg ha -1 was most increased production value of protein yield. Folia Univ. Agric.

Key words: fertility restoration, triticale, yield components, yield quality. Abstract. The studies concern fertility restoration and yield structure as well as grain quality of F 1 triticale hybrids with T. timopheevi cytoplasm. Among twenty studied hybrids only two exhibited full fertility. None of the genotypes maintained male sterility. A majority of hybrids showed a partial male fertility. The number of grains per ear in hybrids was however similar to that of parents which indicates that triticale is tolerant to not complete fertility restoration. The hybrids produced higher yield and showed higher level of other agronomic traits, with nutrient contents in grains being similar to that of the parental forms. Folia Univ. Agric.

8 Abstract. The stability of male sterility of 6 triticale lines and that of restoring fertility of 15 F 1 hybrids, obtained from crossing 3 male sterile lines with 5 genotypes, was determined. The studies were carried out in several environments, representing specified conditions. Male sterility/fertility scores were based on the anther development with rate of pollen shedding during anthesis and on seed set in bagged ears. The stability was assessed by a regression coefficient and deviation from regression of grain number per ear and restoration index of individual genotypes to the environment means. Among male sterile inbreds the most stable were cms Salvo and cms 19 (b close to zero). The hybrids exhibited a varying number of grains per ear ( depending on genotype and environment) which averaged 27.6% lower from that in pollinating genotypes. The restoration index of individual hybrids ranged from 50 to 100% in various environments. The b coefficient for the number of grains per ear and restoration index ranged from 0.12 to 1.20 and from 0.27 to 1.72, respectively. The hybrids with cv. Lamberto and Krakowiak as pollinators exhibited the highest fertility and b below one or close to one. The studies show that the fertility restoration should be assessed in different environments. A significant interaction of female line pollinating genotype for the number of grains per ear indicates that genotype restoration ability should be based on crosses with several female lines. 9.

Abstract. The aim of the study was to determine the relationship between changeability of the dates of agrophenophases and the duration of interphases and the yields of triticale grains and to define a potential decrease in the yield due to changeability of the triticale growing process in northern Poland. The study was based on the results of agrophenological observations and on the values of triticale grain yields at ten COBORU experimental stations and on meteorological ten day period data of The strongest influence on the spring triticale yield in northern Poland had the dates of: sowing, emergence and tillering. A 10 day delay of the dates of sowing, emergence and tillering resulted in a potential decrease in the yield in northern Poland by 6, 8 and 11.5% respectively. Favourable for high yields of spring triticale was the earliest beginning of tillering and possibly late (within the range of dates in the years of the studies) harvest. Good yields resulted also from the lengthening of the period from sowing to harvest and the lengthening of the interphases of shooting heading and, in a determined interval of values, wax maturity harvest. 12.

Key words: fore forecrops, intercrops of spring triticale with lupines, successive effect. Abstract. The field experiment has been caring out on a good rye soil complex with winter wheat planted in various crop successions. The experiment was designed as a split plot in which the 1st factor level was winter wheat and oilseed rape as fore forecrops. Followed by them six forecrops (spring triticale, oat, yellow lupine, blue lupine, and two intercrops of triticale lupines) were planted on plots and the winter wheat in their succession. The objective of this study

10 was to compare five forecrops: triticale, two lupines and two intercrops to the stand after oat. The effect of fore forecrops and forecrops for the winter wheat yield and the grain energy accumulation was investigated. The previous results indicated clearly that the spring triticale lupine mixtures, as the forecrops are valuable for the winter whet production, especially in permanent cereal succession. Winter wheat responded to this forecrops by increased accumulation of the grain energy. The relations between the type of fore-forecrops and subsequent forecrops were statistically proved. Meanwhile, there were no significant differences between fore forecrops on the grain yield of winter wheat. The study has been given the assumption that intercropping of spring triticale with lupines may be relevant factor in alleviation of the negative results of permanent cereal succession. Folia Univ.

In the field micro plot experiment glaucous variety Lamberto and strain RAH 366 with single dominant gene expressed non-glaucous phenotype have been evaluated. The photosynthesis, growth, yielding and epicuticular wax morphology (SEM) have been compared. Glaucous plant epicuticule surface of leaf blades and sheaths were covered with wax formed into tubules, whereas non-glaucous ones had plates. During water deficit environment plants of non-glaucous variety RAH 366 had lower photosynthesis measured by means of gas exchange and chlorophyll fluorescence parameters. Hence, in these conditions, the water use efficiency of non-glaucous plants declined. Folia Univ. Agric.

In a three-year field experiment ( ) the usefulness of chlorophyll meter SPAD- 502 for winter triticale grain yield estimation was investigated. Analysis performed at development stages GS 31, 49 and 65 for three years, taken together, revealed that only in 10% grain yield was determined by SPAD readings, though significant effect was observed for values from GS 49. It was confirmed, on the basis of analyses done for sequent years independently, that grain yield was in a small extent dependent on SPAD readings. In the years 2001 and 2003 a significant dependency of grain yield on SPAD readings at three measurements dates was not observed. Whereas in 2002 such a relationship existed: yield determination was about 36%, significant influence was found for SPAD values at stages GS 31 and 49.

The effect of seven ways of soil cultivation on the spring triticale yielding was studied in a field experiment carried out without replications in the years Different post-sowing ways of cultivation were assigned to the individual treatments, that is: 1. first ploughing 12 cm, 2. cultivator application, 3. disc harrowing, 4. without post-harvest cultivation, including the herbicide Roundup 360 SL, 5. without post-harvest cultivation (without a herbicide), 6. ploughing 20 cm, 7. disc harrowing. Pre-sowing ploughing was carried out on the first five units whereas on plots 6 and 7 the ploughing was abandoned. Only extreme simplifications in the presowing soil preparation significantly reduced the values of most examined parameters, and in consequence caused lower yielding of the triticale cultivated without ploughing. Also the remaining examined parameters reached the lowest values in the case of the treatment with non-ploughing cultivation which, only for the number of plants after germination and the weight of one thousand grains, were not statistically significant. A positive correlation between the grain yield and the final plant number per 1m 2, number of spikelets in an ear, number of grains

16 in an ear and the ear length proved that only the plants with large, well filled ears make it possible to obtain high grain yields providing the number of plants per 1 m 2 is optimal. Folia Univ.

In the research carried out at the Zawady Experimental Station an effect of seven ways of soil preparation before winter triticale sowing was analysed. Among the winter triticale characteristics, statistically significant differences in the number of plants after germination, final plant number per 1 m 2 and the grain yield were found. In all the mentioned cases, the significantly lowest values were obtained in the case of the treatment with the nonploughing cultivation. Also the remaining parameters reached the lowest values for the abovementioned treatment, yet the differences were not significant. The grain yield significantly correlated only with the number of plants after germination and the final plant number per 1 m 2, which suggests that the stand content from the beginning to the end of vegetation shaped the final yield-creating effect.

On the basis of nine-year research no significant effect of five different post-sowing operations carried out to obtain soil compaction on spring triticale yielding was found. The application of a ring roller resulted in an increase in the weight of one thousand grains whereas the use of a light and smooth roller caused an increase in the number of grains in an ear. In agricultural practice the post-sowing application of a cage roller can be advised as it is

17 a factor which positively influences spring triticale grain yield (despite the fact that it was not statistically proved) which, under the discussed conditions, increased by more than half a tonne compared with other cultivation variants. The factors that most strongly modified the grain and straw yields as well as their components were weather conditions which differed in successive growing seasons. Folia Univ. Agric.

With respect to the nutritional requirements of livestock feed, grains of wheat-rye hybrid were characterised by rather low content of K, Ca, Mg, Na, Fe, Mn, Zn and Co but with a satisfying level of P, Cu and heavy metals. Although

18 the K : (Ca + Mg) ratio in grains of spring wheat-rye hybrid was adequate that of K: Na was wide while that of Ca : P and Fe : Mn was rather narrow. The cultivation of spring wheat-rye hybrid in mixtures with faba bean did not in any way significant affect the chemical content wheat-rye grains. They were characterised however, by a higher total protein, Mg, K and Na content while that of fibre, Mn and Zn was low. 29. BARBARA ŚCIGALSKA Folia Univ. Agric.

Results of research constitute a three-year fragment ( ) of strict static field experiment conducted at the Research Unit of the Department of Soil Management and Plant Cultivation, Agricultural University of Krakow localized at Mydlniki near Krakow. A one factor experiment was set up using randomized block method in four replications on proper brown soil of good wheat complex. Spring triticale, Wanad c.v. was the object of research aimed at determining its response to cultivation in a crop rotation and in two species grain crop monoculture with the share of oats, and in a single species monoculture of spring triticale. The average triticale yield for three years was 5.6 t. ha -1 and protein yield 563 kg per ha. Significantly larger yields of grain and protein in relation to single species monoculture were noted when Wanad c.v. was cultivated in the crop rotation and in two species monoculture with the share of oat. The greatest variability of grain and protein yield and also yield forming features, such as number of ears and grain number per ear was registered in the third year of the studies which was the least favourable because of the weather conditions. Spring triticale cultivation in grain monoculture with the share of oats may alleviate negative effects of a single species monoculture of spring triticale. Folia Univ. Agric.
