Abstract:
The plot test of drought resistance soybean germplasms was carried out in Shanxi province and at Dunhuang,Gansu province,in order to analyze the reliance of different methods for drought resistant identification. The results showed that the reliance of applying fuzzy comprehensive decision or comprehensive drought resistant index was supior to leaf wilting degree or seed yield.The key to evaluate the soybean drought resistance lied in character selection, especially the main characters relatived to drought resistance.The results showed that six characters were selected for evaluating the soybeen drought resistance,i.e.seed yield,seed per plant, number of pods per plant, leaf wilting degree,plant height, number of branches.
Key words:
Soybean breeding,
Drought resistant identification
