应用灰色系统理论,分析了16个糯玉米新品种的11个主要农艺性状与鲜穗产量的关联度,结果表明,各性状与鲜穗产量的关联度排序依次为穗长>穗粗>鲜百粒重>株高>行粒数>出苗至采收天数>穗行数>轴粗>秃尖长>鲜出籽率>穗位高。因而,糯玉米的鲜穗产量与穗长、穗粗、鲜百粒重关系最为密切,与鲜出籽率、穗位高的关系最为疏远,与其他农艺性状的关系一般。
The gray system theory was used to analyze the correlation between 11 main agronomic traits and fresh ear yield of 16 new waxy corn varieties. The results showed that the order of the correlations between the traits and fresh ear yield was in the following order: ear length> ear diameter> Grain weight> Plant height> Number of rows> Emergence to harvest days> Ear rows> Shaft thickness> Bald length> Fresh seed yield> Ear height. Therefore, the fresh ear production of waxy corn was most closely related to ear length, ear diameter and fresh weight per 100 kernels, and was most distant from the relationship between fresh-yielding seed weight and ear height, which was generally related to other agronomic traits.
