“…At the same time, Tulun 15 has a different dominant Vrn gene than theirs, namely, Vrn-B3 typical of Chinese wheat (Zhang et al, 2008). Its other dominant gene is Ppd-D1a (Berezhnaya et al, 2021) that is alien not only for Siberia but for Russia as well (Balashova, Fait, 2021). Note the Prilenskaya cultivar zoned in Siberia also has a dominant Ppd-D1a gene (Lysenko et al, 2014).…”

The global and local climate changes determine the producing of highly-adaptive common (bread) wheat commercial cultivars of a new generation whose optimal earliness matches the climatic features of the territory where the cultivars are farmed. Principal component analysis involving our own and published data has been applied to investigate 98 commercial common wheat cultivars from Western and Eastern Siberia comparing their morphotypes; cultivar zoning time; length of the vegetation period; 1000-grain weight, and inheritance of spring growth habit. It demonstrated that the dominant Vrn gene polymorphism determining the spring growth habit of the Siberian cultivars was minimally polymorphic. In 75 % of the tested cultivars, the spring growth habit was controlled by digenic, namely dominant Vrn-A1 and Vrn-B1 genes. In 25 % of them (24 cultivars), spring growth habit is controlled by a single gene. In 19 and 5 of these cultivars spring growth habit is controlled by only one dominant gene, Vrn-B1 or Vrn-A1, respectively. In cv. Tulun 15, a trigenic control was identified. A conclusion about the optimality of the digenic control for the climatic conditions of both Western and Eastern Siberia has been confirmed. However, since none of the tested cultivars had the dominant Vrn-D1 gene typical of the regions of China and Central Asia bordering Siberia, it can be considered as an additional argument in favor of the European origin of Siberian common wheat cultivars. The revealed high frequency of the Vrn-B1c allele in the Western Siberian cultivars and the Vrn-B1a allele in the Eastern Siberian cultivars suggests their selectivity. The analysis also confirmed the dominance of red glume (ferrugineum, milturum) and awned spike (ferrugineum, erythrospermum) varieties in the Eastern Siberian cultivars, and white glume and awnedless spike (lutescens and albidum) ones in the Western Siberian cultivars. Small grain size cultivars are more typical of Eastern than Western Siberia. The retrospective analysis based on the cultivars' zoning time included in the "State Register for Selection Achievements Admitted for Usage" brought us to the conclusion that the earliness/lateness of modern Siberian commercial cultivars was not regionally but rather zonally-associated (taiga, subtaiga, forest-steppe and steppe zones).

“…The search for Vrn gene polymorphisms and studying its influence to the earliness expression has been one of the key directions of the Russian wheat breeding programs, including Eastern and Western Siberia since dominant Ppd genes are not that widespread in Siberian cultivars (Likhenko et al, 2014;Balashova, Fait, 2021).…”

Aim. The identification of Ppd-1-alleles in winter bread wheat varieties of various origin, including the ones of Ukrainian plant breeding and recombinant-inbred lines Orenburgskaya 48//Cappelle Desprez/2В Chinese Spring, and the evaluation of the effects of allele Ppd-А1_del303, including the interaction with different alleles of gene Ppd-B1, by the duration of the period before heading and the related agronomically valuable traits. Methods. DNA extraction, allele-specific PCR, agarose and polyacrylamide gel electrophoresis, phenological observations, evaluation of frost resistance in seedlings, and analysis of morphobiological traits and elements of yield structure. Statistical analysis of the obtained data was carried out in Microsoft Excel. The significance of the difference between samples was assessed by Fisher's F test. A difference of p < 0.05 was considered statistically significant for all indicators. Results. The marking of 30 varieties of different origin and 64 recombinant-inbred lines of Orenburgskaya 48//Cappelle Desprez/2B Chinese Spring winter bread wheat was carried out to identify the alleles of the Ppd-A1 gene. The polymorphism of varieties and populations of recombinant-inbred lines in the northern Black Sea region (Odesa) was evaluated for ten traits: frost resistance of plants in the seedling phase, winter hardiness, duration of the period before heading, plant height, grain number per spike, grain weight per spike, thousand grain weight, number of productive tillers per unit area, harvest index and grain yield. The comparison of the lines evaluation data in terms of agronomic traits and the results of the genotypes identification allowed us to identify the influence of Ppd-A1 gene alleles and various combinations of the alleles of Ppd-A1 and Ppd-B1 genes on these traits. Conclusions. A higher prevalence of the Ppd-A1_del303 allele was found both among varieties and recombinant-inbred lines. The genetic differences by the Ppd-A1 gene (Ppd-A1_del303 or Ppd-A1b) are significantly related only to frost resistance of seedlings in the absence of significant differences in other traits. The interaction between Ppd-A1b and Ppd-B1c alleles contributed to the acceleration of early maturity and the formation of the highest indicators of grain weight per spike, thousand grain weight, harvest index, and grain yield. The replacement of the Ppd-A1b allele with Ppd-A1_del303 led to a decrease in the effect of the dominant Ppd-B1c allele on accelerating heading and negatively affected the grain weight per spike, thousand grain weight, harvest index and grain yield compared to the Ppd-A1b Ppd-B1c genotype.

Ancient and modern 183 varieties of winter and 23 spring types of development of bread wheat (Triticum aestivum L.) selected Ukrainian state institutions and private companies are characterized by alleles of Ppd-D1, Ppd-B1, and Ppd-A1 genes. Allele-specific molecular markers, proposed in the scientific literature, were used to identify carriers of the Ppd-D1a, Ppd-D1b, Ppd-D1c, Ppd-D1d, Ppd-B1a, Ppd-B1c, Ppd-A1b alleles. According to the results of PCR analysis, the most widespread among the studied winter cultivars was observed in the dominant allele Ppd-D1a (91.9 %) with a range from 80.0 % in the sampling of varieties of the Northeast (Kharkiv, Sumy) to 95.0 % in southern cultivars (Odesa, Kherson), and in spring – recessive Ppd-D1c (43.5 %). The share of carriers of various recessive alleles of the Ppd-D1 gene among spring varieties is 73.9 %, and among winter – 8.1 % and, except for Borovitsa and Talisman consists of cultivars created by the late 60 – early 70 years of last century. The frequencies of the Ppd-B1a and Ppd-B1c alleles are quite small. The Ppd-B1a allele was found only in three spring varieties, and the Ppd-B1c allele in 5 winter varieties and spring wheat Struna Mironivska, except for the latter cultivar, in all cases found together with the Ppd-D1a allele. The Ppd-A1 gene was present in a recessive state in all studied sorts. Seven different homozygous Ppd-1 genotypes have been determined in the studied cultivars. Samples of winter and spring varieties differ significantly in the quantity and frequency of specific Ppd-1 genotypes. The presence of varieties with monogenic dominant Ppd-D1a or Ppd-B1c control of traits and digenic dominant Ppd-D1a Ppd-B1a genotypes has been marked in spring wheat, as well as monogenic dominant for Ppd-D1a and digenic dominant for Ppd-D1a in winter wheat varieties. In spring cultivars the share of carriers of recessive alleles of Ppd-1 genes is several times higher (69.6 %) than in winter varieties; conversely, the samples of winter varieties have significantly more dominant alleles (91.9 %). Such differences in genotype frequencies are due to the timing of sowing and duration of the natural day at the latitude of the growing region during the growing season of winter and spring varieties.
