Comparisons of the characteristics in drought resistance among soybean (Glycine max (L.) Merril) cultivars

1985

A:PS

Ten soybean cultivars were compared, through various characteristic determination, to verify the differences of drought resistance among cultivars. The correlation of various determinating characteristics was also evaluated. On the basis of yield reduction degree as drought resistance, the cultivar "Acadian" was the best one in drought resistance. The capability of drought resistance was found to be seemly correlated with such characteristics as high plant growth rate and high leaf expansion rate, high root/shoot ratio, low proline accumulation, high germination percentage in polyethylene glycol (PEG) solution and maintenance of high leaf water potential under drought condition. From the data of correlations between characteristics, it seemed that leaf water potential was possible to be used as an indicator for drought resistance. [AS]
