The study examines the level of manifestation of the heterosis effect in hybrid populations, which increases the efciency of the selection process of winter wheat based on the number of grains in the main ear. 30 hybrid combinations were created using a complete diallel crossings scheme for six varieties of soft winter wheat with wheat-rye translocations (WRT): 1AL.1RS – Ekspromt, Zolotokolosa, Kolumbiia and 1BL.1RS – Kalynova, Svitanok Myronivskyi, Lehenda Myronivska. The Svitanok Myronivskyi variety used in crossbreeding gave the hybrids inheriting the studied trait mainly by additive effect, while with the use of Ekspromt, Zolotokolosa, Lehenda Myronivska, Kalynova, Kolumbiia varieties the hybrids inherited the trait by non-additive effect. The best in terms of the number of cases with high effects of total combining ability (TCA) on the number of grains per main ear were the WRT-carriers varieties: 1BL.1RS – Lehenda Myronivska, 1AL.1RS – Zolotokolosa and Kolumbiia. Regardless of the weather conditions of the year, a heterosis effect was found in the 1BL.1RS / 1BL.1RS crossing group and transgressive forms were selected in the following generations. The highest value of the trait was found in the following populations: F2 – Zolotokolosa / Kolumbiia, Svitanok Myronivskyi / Ekspromt (32.1 % each), Kalynova / Zolotokolosa (31.7 %); F3 – Kolumbiia / Zolotokolosa (41.5 %), Kolumbiia / Ekspromt (36.5 %) and others. In most of them, the translocation 1AL.1RS carrier varieties were the parent components. Key words: soft winter wheat, wheat-rye translocations, number of grains per main ear, general combining ability, specifc combining ability, heterosis, transgressions.

Purpose. To determine the genetic effects of WRT 1AL.1RS and 1BL.1RS on the yield, plant productivity elements and quality indices of recombinant lines, to determine the effectiveness of using each of the WRT for creating more perfect varieties of soft winter wheat in these traits under soil-air drought in the steppe zone of Ukraine and development of breeding techniques to reduce the negative effects of translocation to produce genotypes with high quality indices of valuable and strong wheat grain. Methods. Field experiments, intraspecific hybridization, evaluation of breeding material in the field, methods of laboratory determination of baking quality indices of grain, electrophoresis of spare proteins, statistical. Results. Under arid conditions of the South of Ukraine on the large experimental material of breeding process, a positive effect of 1AL.1RS on the yield of recombinant lines and the main elements of plant productivity were determined, which was manifested against the background of simultaneous positive effect of this transposition on the drought and heat tolerance. The use of 1BL.1RS in wheat breeding in this region is less promising technique. It has been determined that introduction of 1AL.1RS, 1BL.1RS translocations into local gene pool of soft winter wheat by hybridization changes the grain quality indices. In particular, the protein content tends to increase more significantly under the influence of 1BL.1RS translocation. It has been shown that the frequency of obtaining recombinant lines which combine high yield and sufficient level of baking properties (not lower than valuable and strong wheat) is quite low (1,7–6,1%), but introgressive lines with 1AL.1RS have the advantages in this parameter. Using such genetic factors as hybridization combining WRT with alleles with high positive effect on baking properties, and also creating heterogeneity in the composition of genotypes with and without WRT, one can purposefully reduce the negative impact of WRT on the quality of soft winter wheat grain and create varieties with quality parameters of valuable and strong wheat. Conclusions. In general, the results achieved give reason to assert that the use of WRT 1AL.1RS is a promising direction for further breeding increase of genetic capacity of soft winter wheat varieties in the arid conditions of the South of Ukraine. As a result of full cycle of breeding process on the material with 1AL.1RS WRT a series of varieties of soft winter wheat ‘Zhytnytsia odeska’, ‘Oktava odeska’, ‘Liha odeska’, ‘Duma odeska’, ‘Versiia odeska’, providing 10 – 15% increase in yield to standards was created and included in the State Register of Ukraine and Moldova.

The paper reveals the results of study on the parent components of soft winter wheat selection of the V.M. Remeslo Myronivka Institute of Wheat of the National Academy of Sciences of Ukraine and the Institute of Plant Physiology and Genetics of the National Academy of Sciences of Ukraine. The fndings demonstrate dependence of grain formation in the frst generation of interspecifc hybrids of soft winter wheat on the environmental factors and on wheatrye translocations 1AL.1RS and 1BL.1RS in the parental forms. The results of the analysis of variance show that the efciency of crossing and the percentage of grain formation signifcantly in the feld depended on the interaction of factors (47.7 %, p ≤ 0.05), on weather conditions (30.4 %) and the variety genotype (21.5 %) and did not depend signifcantly (0.4 %) on unaccounted factors (coincidence of ﬂowering dates of the components involved in hybridization). In the group of crosses 1BL.1RS / 1BL.1RS, the average percentage of grain formation was the highest for three years (2016– 2018) and did not diﬀer signifcantly – 50.1 %; 55.5 % and 49.8 %. The maximum average indicators for the research years (48.3 %) and under favorable weather conditions of 2017 (68.3 %) were obtained using the crosses of the variety of Svitanok myronivskyi 1BL.1RS as a parent form, and the minimum (37.1 % and 45.2 %, respectively) – using the variety of Kalynova 1BL.1RS. The results of the study show that hybrid combinations of Svitanok myronivskyi / Kalynova (56.1 %), Lehenda myronivska / Kalynova (54.6 %), Zolotokolosa / Svitanok myronivskyi (53.3 %), Lehenda myronivska / Ekspromt (52.4 %), Kolumbia / Zolotokolosa (48.1 %), Svitanok myronivskyi / Lehenda myronivska (47.6%) and Svitanok myronivskyi / Zolotokolosa (46.4 %) were the best in terms of the average percentage of grains formation for the research years. Key words: soft winter wheat, wheat-rye translocations, grain formation, weather conditions, genotype.
