“…Заразом відмінності груп ліній з альтернативними алелями гена Ppd-D1 або різною тривалістю потреби в яровизації за ВР, МТЗ і УЗ виявилися не істотними. Хоча дані результати щодо впливу алельних відмінностей гена Ppd-D1 на ВР, МТЗ і УЗ не відповідають раніше одержаним з використанням ліній аналогів стародавніх сортів півдня України [9] та рекомбінантно-інбедних ліній Одеська 16 / Безоста 1 [14]. Це, імовірно, обумовлено сильним впливом на рівень продуктивності озимої пшениці умов середовища та генотипів сортів, які використані при створенні вихідного матеріалу, що залучений до досліду [15].…”

“…Алелі генів, що визначають потребу в яровизації й фотоперіодичну чутливість, впливають на адаптивність сортів пшениці в різних кліматичних умовах, змінюючи не тільки темпи проходження ключових фаз розвитку, але і врожай [7]. Так, присутність в генотипі озимої пшениці домінантної алелі гена Ppd-D1а або Ppd-B1с сприяє значному скороченню періоду до колосіння та суттєвому збільшенню урожаю зерна в умовах Північного Причорномор'я [8,9]. В той же, час гени Vrd1 або Vrd2 прискорювали колосіння, але не впливали на кількісні характеристики складових урожаю в умовах Одеси [10].…”

Aim. To determine the influence of alternative alleles of the Ppd-D1 gene and phenotypic differences in the duration of the need for vernalization and their interaction on earing time and grain yield of recombinant lines of bread winter wheat. Methods. Growing plants in the field and on the vegetation site, PCR with specific primers for Ppd-D1 and Ppd-B1c genes, phenological observations, artificial vernalization, statistical analysis. Results. 136 recombinant F7 lines from crossing [F1 (Chaika//Cappelle Desperez/2В Chinese Spring) / Kharkivska 81] F2 / Obryi identified by alleles of the Ppd-D1 gene, characterized by the duration of the need for vernalization, duration of the period to earing, plant height, weight 1000 grains and grain harvest. Conclusions. Genotypes with the presence of the Ppd-D1a allele eared 2.9 days earlier than those with the Ppd-B1b allele, and the lines with a 30-day need – one day earlier than those with a 40-day need for vernalization. Different combinations of alternative alleles of the Ppd-D1 gene and characteristics of the lines regarding the need for vernalization significantly influenced the differences in the duration of the period before heading and the weight of 1000 grains. Among the lines that significantly exceeded the control varieties Antonivka and Kuyalnik in terms of yield, those with a different combination of two traits were found, but the share of lines with a combination of the Ppd-D1a gene and 30 daily need for vernalization was greater and they formed the largest yield.

“…The differences in the rate of development for bread wheat are mainly related to the impact of dominant gene Ppd-D1а, which spread widely among the varieties in temperate zones (Langer SM et al, 2014), predominantly affecting winter type of development. Allelic differences for gene Ppd-D1 are among the most relevant factors, defi ning the variability of winter wheat varieties in terms of adaptivity and performance in specifi c cultivation regions (Worland AJ et al, 1998;Síp V et al, 2010;Grogan SM et al, 2016), including Ukraine (Bakuma АО et al, 2018). On the contrary, allele Ppd-A1a.1 and Ppd-B1a.1 (Nishida H et al, 2013;Seki M et al, 2011) are rare.…”

Aim. To identify and evaluate allele frequencies of Ppd-D1a, Ppd-B1a, Ppd-B1c and Ppd-1 of the genotypes of spring bread wheat varieties from various climatic zones. Methods. DNA isolation, allele-specifi c PCR, electrophoresis in agarose and polyacrylamide gel, statistical analysis. Results. 137 varieties of spring bread wheat of various origin were detected to identify Ppd-1 genotypes of Ppd-D1a, Ppd-B1a and Ppd-B1c allele carriers. The results for the total sampling of the varieties under investigation and the sampling of Asian varieties yielded six different Ppd-1 genotypes in each. As for samplings of other regions, there were from two (Mexico) to four (Europe, the USA, Canada, Ukraine) Ppd-1 genotypes. In the total sampling of varieties, there was a high incidence (20.5 %) of genotypes, dominant only in allele Ppd-D1a, varying from 0 (Russia) to 85.0 % (Mexico). The incidence of the genotypes with monogenically dominant Ppd-B1a (7.3 %) or Ppd-B1c (5.1 %) in the total sampling, was considerably lower. These genotypes were most common for the sampling of the varieties from the USA and Canada (25.0 and 16.7 % respectively). Digenically dominant Ppd-D1a Ppd-B1a genotypes were found in the total sampling with relatively low incidence (7.3 %), and were notable for the varieties from Asia (33.4 %), Mexico (15.0 %), Ukraine (13.1 %), and Europe (3.1 %). The digenically dominant genotype Ppd-D1a Ppd-B1с was found only in the Japanese variety Konosu-25. Gene Ppd-A1 was present in all the spring varieties under investigation in its recessive state. Conclusions. Out of three dominant alleles in the studied sampling, the highest incidence was noted for allele Ppd-D1a (28.5 %). All the varieties from Mexico, present in the set, carry this allele. At the same time, it was not found in any variety from Russia. Allele Ppd-B1a was detected in the varieties from all the regions with the incidence of 7.7 (Russia) -44.4 % (Asia). Allele Ppd-B1c was sporadically present in the varieties from Russia, Ukraine, the USA, Japan, and Brazil, and its incidence in the total sampling was insignifi cant (5.8 %). The varieties, identifi ed by the allelic status of Ppd-1 genes, may be used as donors for selection and determination of the infl uence of alleles for each gene by the development rate and related economically valuable traits of bread wheat.

In recent years, there has been a significant change in climatic conditions affecting the cultivation and yield of winter wheat. Therefore, the creation of wheat varieties with high adaptive potential is one of the main tasks of modern breeding. A significant component of the overall adaptive potential of winter wheat is winter hardiness, which is determined by a set of characters enabling plants to overwinter. To a large extent, winter hardiness is determined by gene systems that control vernalization requirement duration, photoperiod reaction, and frost resistance. The research is aimed at determining the features of modern winter wheat varieties developed at the V. M. Remeslo Myronivka Institute of Wheat of the National Academy of Agrarian Sciences of Ukraine in terms of winter hardiness components and adaptive potential in the environment of the Central part of the Ukrainian Forest-Steppe. Winter bread wheat varieties Estafeta myronivska, Hratsiia myronivska, MIP Assol, and Balada myronivska were studied. They also were crossed on incomplete diallele scheme with three near-isogenic lines derived from Erythrospermum 604 with different alleles of Vrd genes 1) Vrd1Vrd1vrd2vrd2, 2) vrd1vrd1Vrd2Vrd2, and 3) vrd1vrd1vrd2vrd2. It was established that vernalization requirement duration in the varieties Estafeta myronivska and Balada myronivska was short whereas in the varieties Hratsiia myronivska and MIP Assol it was medium. All the varieties studied have medium photoperiod sensitivity. The results of the hybridological analysis indicate the absence of the Vrd1 and Vrd2 genes in the varieties. Frost tolerance of these varieties is at the same level and higher than in the highly tolerant to the low temperatures variety Myronivska 808. Thus, the results indicate the possibility of recombining different levels of expression of these traits in genotypes by breeding efforts. This has great practical importance in farming, because in recent years the areas of crops harvested late (corn, sunflower, etc.) in the production conditions has significantly increased. It causes a shift in sowing dates of winter wheat to a later period. In this case, varieties Estafeta myronivska, Hratsiia myronivska, MIP Assol, and Balada myronivska are able to undergo sufficient hardening, to satisfy the vernalization requirement, and to form a high level of winter hardiness. Their relatively medium photoperiod sensitivity allows vegetation to be restored a little earlier in the spring and winter reserves of moisture to be used more effectively.
