摘  要:Maize is the main grain crop and important forage crop in China. The correlation between ASI and yield of maize inbred lines and whether ASI and the ASI extension time(Dct) of maize inbred lines could be used as a direct indicator of drought resistance of maize inbred lines were explored. The results showed that the goodness of fit of ASI and Dct with DI were 0.478 and 0.829, respectively, and the ASI had an extremely significant negative correlation with yield per plant. ASI and Dct could be used as a parameter to evaluate drought resistance of maize inbred lines, but Dct was more effective than ASI in determining drought resistance index(DI) of maize inbred lines.
