Comparative Study on the Drought Resistance of Maize Hybrids

Zhang Li-hua, Hongxiang Zhao, Tan Guobo

Abstract

In order to compare the drought resistance of maize hybrids,carrying on the test with 32 widespread maize hybrids in the mobile awning.There are CK(irrigation 300 mm) and water stress(irrigation 100 mm) two treatments in the growth stage.There were eleven critical targets include measuring ASI,LRI and RWL etc.in connection with maize drought resistance.And screen out nine correlative and prominent ones.Overall merit nine critical and seven drought resistant targets using the method of fuzzy membership functions.Eight hybrids with higher drought resistance,nineteen hybrids with medium drought resistance were selected.
