本文以我所培育的10个杂交组合和生产上应用的杂交种以及亲本自交系为试验材料、进行了8个性状的（株高、穗位、茎粗、穗长、穗粗、穗行数、行粒数、千粒重）杂种优势率和双亲平均值与F_1各性状的相关系数的分析。明确了株高、穗位、穗长、行粒数、千粒重优势指数最大；穗行数、穗组为中等；茎粗为最小。双亲和双亲平均值与F_1代的株高、穗长、行位数、千粒重等4个性状呈极显著正相关；穗位性状呈显著正相关；茎粗、穗粗、穗行数三性状表现相关不显著，通过分析，为培育亲本，组配优势大，配合力高的杂交种提供参考。
In this study, the genetic characteristics of eight traits (plant height, ear position, stem diameter, ear length, ear diameter, ear width Number of rows, grain number, 1000 - grain weight) analysis of the correlation coefficients between heterosis rate and average of parents and F_1 traits. Clear plant height, ear position, spike length, grain number, grain weight index of the largest grain weight; spike rows, spike group is medium; stem diameter is the smallest. The average of parents and parents was significantly and positively correlated with F_1 generation of four traits, including plant height, spike length, number of rows and 1000-grain weight. There were significant positive correlations among ear traits and spike traits, The correlation is not significant, through analysis, to cultivate the parents, the group with advantages of large, high combining ability provide a reference.
