Abstract
The article presents the data of productivity of spring durum wheat varieties of various morphotype in the northern regions of Chuvash, and the purpose is to select the most promising and to find the opportunities of breeding and technological adaptability of spring durum wheat in the region. There were five varieties participated in the trials, they are ‘Bezenchukskaya Niva’, ‘Bezenchukskaya 200’, ‘Bezenchukskaya 205’, ‘Bezenchukskaya 209’, ‘Luch 25’. The results of the biometric analysis of spring durum wheat showed that plant height of the varieties ranged from 74.6 cm to 104.8 cm. The plants of the variety ‘Bezenchukskaya 200’ were found the shortest, the plants of the variety ‘Bezenchukskaya 205’ turned to be the highest. The varieties ‘Bezenchukskaya Niva’ and ‘Bezenchukskaya 209’ showed the best indexes of productive tillering. The best indexes of a yield structure were found in the variety ‘Bezenchukskaya Niva’ with 5.1 cm of a head length, 22.9 seeds per head and 1.12 g of seeds per head. The least indexes were found in the variety ‘Bezenchukskaya 205’ with 16.8 seeds per head and 0.76 g of seeds per head. It has been determined that a number and weight of seeds per head of the varieties changed proportionally to length of head. 1000-kernel weight ranged from 42.32 to 53.27g depending on the variety. The variety ‘Bezenchukskaya Niva’ produced the largest yield (34.1 hwt/ha), the variety ‘Bezenchukskaya 205’ showed the least productivity (19.6 hwt/ha).
