Title
Evaluation of Drought Tolerance of Rapeseed (Phaseolus vulgaris L.) Genotypes in Laboratory
Authors
Abstract
Drought stress in the major affecting factor in crop production of many parts of the world. This study was done to evalute the effect of drought tolerance an ten common bean variation of germination stage.The experiment was conducted in a RCBD Design with factorial arrangement in 3 replications. The first factor was stress condition which induced by polyethylene glycol at zero, -4, -8 and -12 bar in laboratory of guilan agriculture school was evaluated at (2013/10/23).
The result of cluster analysis based on UPGMA Algorithm grouped genotypes at no stress, -4, -8, -12 bar osmotic condition in 3, 2, 3 and 3 group respectively. Cluster analysis of genotypes at the 4 stress condition were grouped genotypes x environment interaction in 4 groups. Accuracy of cluster analysis revealed by discriminant analysis with a 90٪ rate.
