Nurscia sp. Clubiona sp.[9], Clubiona brevipes Clubiona sp. Pirata hurkai Pirata knorri (Scopoli, 1763). The results of study of the spiders fauna of Daghestan on 2011 were summed up at most in the work. The annotated lost of species was cited according to the world catalogue of Norman Platnik [1]. By the present time the composition of species of studied district includes 311 species, from which 59 species are cited as new for Daghestan, and 2 species (Drassodes archibensis Ponomarev & Alieva, 2008, Drassodes dagestanus Ponomarev & Alieva, 2008) are described as new for science. The indicated specimen earlier as sp. are identified to species the species Nurscia albosignata Simon, 1874, earlier was identified as Nurscia sp. [8], the species Clubiona alpicola Kulczynski, 1881, earlier was identified as Clubiona sp.[8], and the species Clubiona brevipes Blackwall, 1841, earlier was identified as Clubiona sp.[8]. The mistaken definition is corrected the species Pirata hurkai Buchar, 1966, earlier identified as Pirata knorri (Scopoli, 1763).

The top cross method for assessing combining ability more economical and less laborious compared to diallel analysis, and also allows the breeder to obtain quite valuable information about the inbred material. In this research, the determination of the general (GCA) and specific (SCA) combining ability of barley (Hordeum vulgare L.) hybrids in two regions of Kazakhstan contrasting in soil and climatic conditions, the role of additive and non-additive genes in the determination of the traits under study has been revealed. It is concluded that the predominance of additive gene interactions in the control of the traits understudying the conditions of the Aral Sea region indicates the possibility of effective selection already in the F2 generation, and in the piedmont zone of the Almaty region, due to the high determination of these traits by dominant genes, it is necessary to differentiate the populations of hybrids, starting from the first generation and further selection shall be carried out in several cycles until the achievement of homozygosity of loci carrying dominant genes. Consequently, the genetic contribution of the additive and non-additive effects of genes to the determination and inheritance of the studied traits significantly depends on the conditions of growing the genotypes of spring barley. Of greatest practical interest are the varieties Rihane, WI2291/Roho/WI2269 from the International Center ICARDA and the variety-tester Odessa 100 (Odessa Selection and Genetic Institute, Ukraine) with high GCA and SCA effects, little dependent on growing conditions, which are recommended to be used as reliable donors in breeding programs.

The specifics of the soil and climatic conditions of the Aral sea region, Kazakhstan, primarily associated with salinization, various types of droughts, uneven distribution of precipitation during the growing season, and late spring frosts, make it necessary to create crop varieties with resistance to biotic and abiotic environmental factors. In this regard, the expansion of the area under crops of nontraditional salt-tolerant grain crops in the Kyzylorda region is one of the main directions of increasing the sustainability of agriculture in the region. Studies have shown that among the grain crops cultivated in the region, spring barley (Hordeum vulgare L.) is a reliable crop that can make the most of the region's bioclimatic resources to form sustainable yields. The purpose of this study is to create a new promising source material of barley based on a comprehensive study of collection material of various ecological and geographical origin by applying various methods of classical breeding. Based on a comprehensive assessment of the collection material of barley, a working collection of 250 varieties with agronomic resistance to environmental stress factors of the Aral Sea region was created. The selected samples are recommended for use in practical breeding in order to increase the adaptive potential of modern barley varieties.
