It is known that two varieties of wheat are grown in Uzbekistan. Common wheat (Triticum aestivum L.) and durum wheat (Triticum durum L.) are cultivated in the main part of wheat fields. Durum wheat varieties included in the State Register in Uzbekistan are mainly spring and duvarak. Considering this feature and the high quality of the grain, the purchase price is 30-50% more expensive than that of common wheat, they fully meet the needs of the ever-growing macaroni-confectionery industry. Durum wheat grain is the main raw material used in the preparation of pasta and pasta products, as well as in the confectionery industry. In this case, high technological quality of durum wheat grain is required. In the next two years, the purchase price of durum and common wheat grain in the world increased significantly. Therefore, expansion of durum wheat cultivation areas in different soil and climate conditions, improvement of agrotechnology of care, obtaining high and quality grain harvest are urgent issues.

“…Tajibayev et al [7] analyzed KASIB data from nine trials conducted in 2003-2020 across five sites in Kazakhstan and Russia to evaluate genotype x environment interactions and identify superior germplasm. Analysis of weather variation between years demonstrated that all sites were subject to the same climatic events.…”

Spring durum wheat occupies over 0.5 M ha in Kazakhstan and represents an important domestic and export commodity. This study aimed to characterize 151 durum wheat cultivars and advanced lines originating from eight breeding programs of the Kazakhstan–Siberia Spring Wheat Improvement Network (KASIB) between 2003 and 2018. The phenotypic characterization was performed in two contracting evaluation sites more than 1000 km apart (Almaty in the Southeast and Shortandy in the North) for two years and a total of 11 agronomic traits were recorded. Field trials at both locations followed regional agronomy practices, including sowing, harvesting, and genotype evaluation using a randomized complete block design (RCBD). The growing season was longer in Almaty, resulting in a higher number of grains per spike. Though grains are smaller in size with an overall higher yield, 243 g/m2 versus 170 g/m2, there was no correlation between germplasm performance at the two sites. Molecular characterization was performed with 10 iPBS-retrotransposons primers that resulted in a total of 345 bands and showed a mean polymorphism of 91.9%. Mean values of gene diversity (0.251), Shannon’s information index (0.388), and expected heterozygosity (0.233) revealed a relatively high level of genetic diversity in the KASIB set. AMOVA revealed higher genetic variations due to differences within the populations. Marker-based cluster analysis, including STRUCTURE and neighbor-joining algorithms, divided the material into two populations with clear differences in geographic origin. Superiors and diverse germplasm identified in the study are recommended for marker assisted selection and breeding.

“…One of the modern directions that increase the seed productivity of forage grasses can be adaptive breeding, which is understood as the ability of a genotype to maintain its characteristic phenotypic manifestation of a trait under different environmental conditions and to identify its response under stressful and favorable conditions [13][14][15].…”

Esparcet is not inferior to alfalfa in terms of fodder mass productivity, its nutritional value, content of protein and other nutrients. The main tasks in creating varieties of sainfoin are the selection of new, with high productivity of green mass and seeds, ecologically adapted, with a sufficiently high plasticity to a wide variation in the environmental conditions of its cultivation zones, varieties. The purpose of the research is to assess the plasticity, stability, stress resistance, genetic flexibility and homeostaticity of varieties and promising lines of sainfoin on the basis of “seed yield”. The studies were carried out in 2017-2021. Plot area 20 m2, fourfold repetition, seeding rate 500 pcs. germinating seeds per 1 m2. Seed harvesting was carried out by direct combining. Over the years of research, the seed yield was higher for the Atamansky 20 variety (0.86 t/ha) and the promising lines Sin 3/2004 (0.88 t/ha), Sin 5/2010 (0.91 t/ha) and Sin 3 /2010 (0.94 t/ha). It was established that varieties Veles (bi = 0.15), Atamansky (bi = 0.29) and Zernogradsky 2 (bi = 0.32) react poorly to changing conditions. The values of the stability coefficient of the studied varieties and lines varied from 0.0009 to 0.0076. The sainfoin varieties Sudar (σd2 = 0.0009), Atamansky (σd2 = 0.0010), Veles (σd2 = 0.0015) have the highest stability. The varieties of sainfoin Atamansky, Sudar, Atamansky 20 and Veles were distinguished by wide homeostaticity. they have high plasticity, stability and stress resistance.
