Evaluation of winter wheat genotypes under rainfed farming conditions

Drought has a serious effect on the plant height, the heading date and the grain yield of winter wheat genotypes in Mountainous Shirvan. Genotypes of Sonmez 01, Sheki 1, Bezostaya 1 and Gyzilbughda were noted as the tallest (120.1, 118.9, 114.9 and 111.8 cm), Gyrmizigul 1, Guneshli, Tale 38, Aran, Zirva 85 and Azamatli 95 as the short (83.6, 92.8, 95.8, 92.9, 94.0 and 98.0 cm), respectively, which indicates the adaptability of tall varieties for rainfed conditions. Gobustan, Zirva 85, Ruzi 84 and Gunashli genotypes were noted as the early heading, and Bezostaya 1, Sheki 1, Aran, Tale 38, Gyrmizigul 1 and Baba 75 as the late heading, which is associated with their genotypic characteristics. The yield was changed depending on the genotypic characteristics and annual total precipitation during the growing season. The highest yield was recorded in Gobustan and 7WON-SA no. 465 genotypes, while the lowest yield was in Azeri, Bezostaya 1 and Murov 2 during the research. Adaptation to adverse conditions and high yielding of Gyrmizigul 1 genotype shows the possibility of cultivation under adverse conditions. By adaptability to drought high yield of genotypes can be obtained responding to high soil fertility and favorable climatic conditions. Cultivation of these genotypes in rainfed regions such as Mountainous Shirvan is recommended.
