摘要
利用灰色关联度分析方法,对云南省中北部玉米杂交种区域试验参试组合的产量和产量构成因素进行分析。结果表明:玉米杂交种产量与产量构成因素的关联度大小顺序为:穗粗>穗行数>单株有效穗数>株高>千粒重>穗位高>空杆率>出籽率>穗长>行粒数>生育期。
The correlation between yield and yield component factors were analyzed by method of grey correlative degree analysis for maize hy-brids of Yunnan northern regional trial. The result showed that the values of correlation degree between yield and yield component factors a-mong different hybrids were sequenced as follows：ear diameter 〉 row numbers per ear 〉 ear numbers per plant 〉 plant height 〉 thousand kernel weight 〉 ear position 〉 barren plant percentage 〉 shelling percentage 〉 ear length 〉 kernel numbers per row 〉 maturity period.
