The perspective samples of sesame for breeding purposes in the arid conditions of the Astrakhan region

Within three years in Caspian research institute of arid agriculture 46 samples of sesame from the All-Russia Plant Growing institute’s collection have been studying. As a result of studying on a complex of economically valuable traits 19 perspective samples being valuable for breeding were selected. The allocated samples from Uzbekistan (KK-178, 722, 725, 874, 881), Turkmenistan (K-773), and China (K-997) have shown the highest productivity which exceeded 2.0 t per ha. The productivity of the selected samples is 14.4-24.7 g per a plant. From 19 best samples, samples from Uzbekistan (KK-178, 722, 725) and Turkmenistan (K-773) had the highest coefficient of adaptability reaching 1.6-1.73. The conducted researches showed that soil and climatic conditions of the North of the Astrakhan region are favorable for cultivation of the crop and large seed yields obtaining. All selected samples are differed by fast maturing, quite large seeds with 1000 seeds weight from 2.5 to 3.2 g, good productivity of plants and therefore are valuable material for breeding in droughty conditions of the Astrakhan region.
