Creating the initial material of drought and heat resistance of durum wheat for irrigated lands

The article presents the results of studying a variety of durum wheat for irrigated lands of breeding laboratories for selection and seed production of durum wheat at the Gallaaral Scientific and Experimental Station of Research Institute of Grain and Legume crops. Different variability of the studied characteristics of durum wheat varieties depending on the conditions of their cultivation was revealed. The main results of the study of durum wheat for drought and heat resistance are given. The components of drought and heat resistance selected three varieties of durum wheat with high yield in irrigation. The smallest coefficients of variation were noted for three years in terms of the coagulation temperature of water-soluble proteins in durum wheat leaves, and the highest coefficients of variation were found in the angle of inclination of the flag leaf. A positive correlation was established between the total water content in the leaves, the coagulation temperature of water-soluble proteins in the leaves, and the yield of durum wheat. By the components of drought and heat resistance were selected varieties of durum wheat Mingchinor, Istikbolli, No. 299, No. 566 with high yields in irrigated conditions.
