Abstract
In order to explore the drought resistance characteristics of different consanguinity in maize inbred lines,effect of drought stress on yield component,main agronomic traits,malondialdehyde content,and free proline content in 6maize inbred lines was conducted by pot experiment.The results showed that:Firstly,the difference of agronomic traits in the 6lines reached significant or highly significant level,and highly difference in each property under drought stress.Secondly,drought stress could decrease the drought resistance coefficient for main agronomic trait in each inbred line,especially the strong effect of drought stress on yield component happened in jointing-tasseling stage,followed by tasseling stage,but minimal effect happened in jointing stage.Thirdly,malondialdehyde content and free proline content were accumulated massively caused by the drought stress.And finally,among the 6maize inbred lines,the comprehensive drought resistance of Su 65and D902 were the highest,with stable resistant ability,and with integrated drought resistance coefficient of 0.84and 0.82,and coefficient of variation 11.28%and 9.32%,respectively.But AS-Dan mix was the worst,with resistance coefficient of0.73and coefficient of variation 20.17%,respectively.Therefore,choosing Su 65and D902as parental lines could successfully produce strong drought resistance varieties in corn breeding in Guizhou.
