The work is devoted to the study and comparison of winter and spring forms of barley in terms of yield, crop structure and technological properties. Eight zoned and introduced varieties of winter and spring barley of various botanical varieties were subjected to the study. It has been established that the Master variety has a high coefficient of productive bushiness, due to which there were 3,42 million ears per 1 ha with the largest number of grains per ear - 32 pieces. - and their absolute weight - 42,9 g. The rest of the winter varieties are inferior to it in terms of the number of plants per 1 m2 by 3,4-13,3%, the number of productive stems by 4,4-17,8%, the number of grains in the ear by 3,3-31,2%, absolute mass of grain by 1,2-4,0%. Among the varieties of spring barley, a higher coefficient of productive tillering was noted in the Priazovsky 9 variety, followed by Getman and Vikont, the minimum was observed in the Mamluk variety. According to the results of the research, the Master variety stood out from the winter barley varieties for the better, having the highest coefficient of productive tillering (1,9), the number of grains per ear (32 pcs.) and productivity (3,86 t/ha). Among the spring barley varieties, the Priazovsky 9 variety stood out in the best direction, which has the highest coefficient of productive bushiness (1,36), the number of grains per ear (21 pcs.) and productivity (3,80 t/ha). According to the technological properties of grain, namely the content of protein, starch and extractivity, the leader among winter varieties is the Master variety with an extractivity of 80,9% and Getman of spring varieties with an extractivity of 80,2%.
