Abstract
Utilized the 10 inbred lines of maize and matching the 24 hybrids as materials.By measuring 12 indicators for the maize seedling emergence stage under drought stress on the relative germination ratio,roots relative growth,sprout index of drought resisting,leaves relative water content,seedlings drought stress survival rate,seedling plant height and so on.And by utilized the gray correlation,hybrid heterosis and parent-offspring correlation analysis of corn shoots and identified the drought resistance indicators for evaluation and selection.The results showed seed germination index-tolerance,seedling survival rate could be defined as selection of the drought resistance indexes in maize seedling emergence stage resistance of the primary indicators.Root relative growth,relative water content,seedling height and relative germination rate may be taken as selection of the drought resistance indexes in maize seedling emergence stage resistance of the secondary indicators.
