| 摘 要： | 利用灰色系统理论,对玉米产量和与产量有关的7个农艺性状的关联度进行了分析。结果表明:产量与7个性状的关联度顺序为:百粒重穗长行粒数出籽率穗粗穗行数秃尖长度。因此,选育高产玉米杂交种时,应重视百粒重、穗长和行粒数。

| Abstract: | By using grey correlation analysis method,the relationship of seven yield traits and the yield of maize was analyzed.The results showed that the correlation degree between each trait of maize hybrids and the yield was as follows：100-grain weight〉ear length〉grain number per row〉 grain produced percentage〉ear thickness〉ear row number〉bare top length.Therefore,we should pay attention to 100-grain weight,ear length and grain number per row when breeding. |
