Selective study collection of sorghum adaptability and quality in different regions of Kazakhstan

Natural conditions of different regions of Kazakhstan is sharp,ly continental, deficiency of moisture and high temperatures during the growing season requires introduction in the production not only drought-resistant, but also salt tolerant crops with high and stable yield of green mass and grain. One such valuable fodder, technical and food crop is sorghum.
Currently approved for use in the Republic of Kazakhstan grain varieties 5 and 6 varieties of sweet sorghum, most of which landraces. Selection of new drought-and salt-tolerant varieties of sorghum almost underway, which bring to the need to mobilize the global gene pool of sorghum to solve the problem of effective use of dry and saline lands in Kazakhstan.
According to the project International Center for Biosaline Agriculture (ICBA) in the conditions of the southeast, south and southwest of Kazakhstan tested genotypes of sorghum from ICRISAT, as during the spring sowing, and in summer sowing . The results of these studies for each region selected the most suitable genotypes : the southeast - ICSV 93046, ICSSH 58, ICSR 93039 and SPY 1411; southwest S35, SPY 1411, ICSY 93046, ICSR 93034 and ICSSH 58; south - ICSY 93046 and SPY 1411. Productivity of green mass during the spring sowing, depending on the varieties studied ranged 49.0-73.5 t/ha in the conditions of the southeast, 41.9-46.3 t/ha - southwest, 39.8-44.4 t/ha - southern of Kazakhstan. Productivity of green mass in summer sowing in the southeast and southwest of Kazakhstan ranged 27.67-38.77 t/ha and 27.1-38.5 t/ha, respectively. Biological grain yield grain sorghum genotypes studied to 2.8 t/ha.
Collection of sorghum protein content characterized by 11,0% to 17 ,2%, sugars from 17,2% to 20,8%, 7,0% of amylose to 28,7% compared to local standards Kiz 7, Kiz 94 and Zhetysu 1.
For the regions of Kazakhstan developed technology package for the cultivation and use of sorghum. Of genotypes tested by the method of individual selection and adaptive forms of selected patent pending on sugar and grain sorghum for use in the production of different regions of Kazakhstan.
