| description | The purpose of the research was to evaluate the yield properties and the main parameters of adaptability of safflower (Carthamus tinctorius) varieties in the agricultural climatic conditions of forest-steppe of the Middle Volga Region. The research was conducted in 2017-2019 on the experimental field of the Federal Scientific Center of Bast Crops. The object of research was the six varieties of safflower (Carthamus tinctorius). Meteorological conditions of the growing season can be characterized as dry; the hydrothermal coefficient (HTC) ranged from 0.4 to 0.82 units. The index of environmental conditions varied from – 0.61 to 0.13 units. The most optimal conditions for the growth of culture were formed in 2019 (Ii – 0.13), where the highest seed yield for all varieties was formed – 1.34-1.53 t/ha. Zavolzhskij 1 and Alexandrit varieties were registered with the high yield, whose productivity was 1.37 and 1.42 t/ha, respectively. The coefficient of yield variability was 6,58-14,19 %. On an annual basis, the low variation in yield was observed in the varieties Ershovskij 4 and Astrahanskij 747 (6.58-7.71 %). This fact indicates the stability of these varieties. These varieties had the highest variety stability level and amounted to 0.26 and 0.22, respectively. Varieties Zavolzhskij 1, Astrahanskij 747 and Alexandrit formed large seeds. The weight of 1000 seeds reached 41.4-41.6 g on an average. The fat content in the achenes ranged from 23.70-27.45 %. In the conditions of the Penza region, in terms of environmental adaptability, the best varieties were Zavolzhskij 1 and Alexandrit, whose adaptability parameters were bi = 0.99-1.01; σdr2 = 0.09. The varieties Alexandrit and Ershovskij 4 had the highest values of the stability index (0.17 and 0.20). This fact shows their greater adaptability to specific conditions. |
