摘    要:目的]研究玉米种子活力指标与产量的相关性,为通过改良种子活力提高玉米产量提供参考依据。方法]以7个玉米自交系为母本,5个自交系为父本,按不完全双列杂交试验设计组配了35个杂交组合,田间和室内测定种子活力相关性状出苗势、发芽率和产量等指标,进行相关分析。结果]田间活力指数与室内发芽势、发芽率、发芽指数、室内活力指数等指标显著正相关。田间测定活力指数与产量极显著正相关,室内发芽活力指数与产量显著正相关,其他种子活力指标与产量相关不显著。结论]室内发芽试验各指标与田间活力指数相关系数均达极显著水平,室内发芽试验可以预测田间成苗情况。

Abstract:Objective] The study aimed to study the correlation analysis between the seed vigor and maize yield,which provided the reference base for increasing the maize yield through the improvement of the seed activity.Method] With 7 maize inbred lines as the female parents and 5 inbred lines as the male parents,35 crosses were made by the incomplete diallel cross design and the seed vigor related traits such as the indexes of the germination energy,germination percentage and yield were determined in laboratory and field to make the correlation analysis.Result] The seed vigor index in the field showed the significant positive correlations with the indoor germination energy,germination percentage,germination index and indoor vigor index etc.The vigor index measured in the field had an extremly significantly positive correlations with the yield,the indoor vigor index showed a significant positive correlations with yield and other seed vigor index had no significant correlations with the yield.Conclusion] The correlation coefficient of each germination index in the indoor test with the vigor index in the field all reached the extremly significant level,so the indoor germination test could predict the survival rate of the seedlings in the filed.
Keywords:Maize  Seed vigor  Correlation analysis
