“…This approach is applied for breeding of many crops [19,20]. To comprehensively assess the ability of a particular genotype to form economically important production in the research region, several parameters are calculated that reflect ecological adaptability [21][22][23][24] such as the coefficient of ecological variation, genotypic effect, plasticity, stability, homeostability, breeding value. As far as the authors are concerned, there are no publications on the possibility of using these coefficients for evaluating herbaceous raw material crops.…”

Since the registry of common oregano (Origanum vulgare L.) cultivars does not involve regionalization, a comprehensive study of cultivars bred by different institutions in the intended cultivation region is valuable and relevant. The objective of the research was to assess the possibility of using various indices of ecological adaptability originally developed for grain crops for their use in the most adapted genotypes’ selection (breeding samples and cultivars) of Origanum vulgare L. to the temperate climate of the Crimean Peninsula. The research was carried out in the piedmont zone of Crimea from 2016 to 2019. The study material consisted of breeding samples No. 10 and No. 82 from the collection of FSBSI “Research Institute of Agriculture of Crimea”, as well as cultivars Zima, Raduga, and Slavnitsa selected by the All-Russian Scientific Research Institute of Medicinal and Aromatic Plants (ARSRIMAP). Genotype had the greatest influence on yield of fresh oregano material (43%) with the influence of the weather conditions of the year being 2%. On the contrary, meteorological conditions had a much greater effect on the essential oil accumulation and its areal yield, which were 30% and 25%, respectively. In terms of the coefficient of ecological variation of fresh yield, sample No. 82 and Slavnitsa cultivar were the best (11.47–16.7%). The local genotypes No. 10 and No. 82 varied less by the essential oil content and its yield. The genotype effect value was greater than 0 in the Raduga cultivar and local genotype No. 82 for the yield, but only in No. 82 genotype for the other two characteristics. Cultivars Zima and Raduga were classified as intensive (bi > 1) by the environmental flexibility of fresh yield, while local genotype No. 82 and Slavnitsa cultivar formed the group of intensive ones by essential oil content and essential oil yield. Local genotypes No. 10 and No. 82 were better than the introduced cultivars in terms of essential oil content homeostability and essential oil yield (Hom = 1.91–2.18). Thus, local genotypes proved to be more adapted to the region’s conditions in terms of essential oil accumulation. However, they were inferior to the registered cultivars of ARSRIMAP breeding in terms of fresh yield.

One of the main ways to obtain consistently high yields in Siberian conditions is the use of adaptive varieties. Selection plays a key role in solving this problem. Success in breeding for resistance to biotic and abiotic stresses depends on the correct choice of initial parental forms for crossing. The purpose of the study is to evaluate varieties and promising breeding lines of soft winter wheat of various ecological and geographical origin in terms of productivity and adaptive potential. The results of the study of 68 varieties and breeding lines of winter soft wheat are presented. The studies were carried out on the experimental field of the Siberian Research Institute of Plant Growing and Breeding, a branch of the Institute of Cytology and Genetics of the Siberian Branch of the Russian Academy of Sciences. The most favorable conditions for the formation of the winter wheat crop were formed in 2021 (Ij=125.1). The least favorable conditions developed in 2020 (Ij= -171.2). The most winter-hardy varieties were Scepter, Novosibirskaya 32, Pamyati Chekurova, Omskaya 6. The Volzhskaya variety showed high plasticity (bi=1.49), but was not stable over the years. The most stable varieties among highly productive samples were Novosibirskaya 32 (δd² = 13.75), Lutescens 261-3 (δd² = 16.86), Pamyati Chekurova (δd² = 13.95), Zhemchuzhina Povolzh’ya (δd² = 10.33), Volzhskaya 22 (δd² = 22.70). Genotypes combining high rates of plasticity and stability Lutescens 261-3 (bi=1.26; δd²= 16.86) and Volzhskaya 22 (bi=1.97; δd² = 22.70). Samples of Pamyati Chekurova, Scepter, Omskaya 6 and Chekh 16 stood out for a number of indicators: in terms of stress resistance Уmin - Уmax = -51.9 ÷ -282.5; in terms of genetic flexibility (Уmax+Уmin)/2 = 568.8÷651.8; by yield variability V = 4.6÷26.4%; according to homeostasis Hom = 8.13÷94.88; by breeding value Sc = 391.3÷521.5. These samples are of interest in the selection of winter soft wheat to improve adaptability
