مطالعۀ همبستگی صفات زراعی ارقام ماش در دو شرایط تنش خشکی و بدون تنش در منطقۀ سیستان

To evaluate the agronomic characteristics of six mungbean varieties under normal and drought stress conditions, the experiment was conducted in a randomized complete block design with three replications at Zahak research station. Irrigation in both stress and non stress environments up to 50 percent flowering were the same. Environments with drought stress, irrigation, 50 percent of flowering to maturity and harvest the product was discontinued. Factor analysis based on principal component analysis and rotation Varimax showed that the first three factors in the environment of overall stress on the 98/89 percent and 90.52 percent of non-stress environment variables changes should be explained. Environmental stress in the first factor 45.25 percent of the variance among the traits belonged to this factor as a cause of undesirability was named. Second and third factors in stress environment 26.40 and 18.32 percent of the variation between traits and were justified as seed weight and pod size factors were named. In the first operating environment without the stress of 42.71 percent of the variance between the characters and their assigned role in the variations can be played. Under this factor was named as the cause undesirability. Second and third factors 26.12 and 21.69 percent of the variation and characteristics were explained as factors of production and yield components were named. Overall results show the effect of environmental factors on the extracted factors, the percentage variations between the characteristics and traits by factors correlated with each factor is.
