摘要: 为了探索西南地区糯玉米主要农艺性状与糯玉米鲜穗产量的关系,为糯玉米育种提供理论依据。通过采用灰色关联度分析法,对2012年国家西南区鲜食糯玉米区试的14个组合的10个农艺性状与鲜穗产量进行了综合分析与评价研究。结果表明:糯玉米的农艺性状与鲜穗产量关联度大小依次为:穗行数>穗粗>穗长>行粒数>出苗-采收>株高>秃尖长>出籽率>百粒重>穗位高。由此得出,穗行数是影响糯玉米鲜穗产量的主要因素,穗位高对产量影响较小。

Abstract: In order to research relation of fresh ear yield and main agronomic characters, we provide a theoretical basis to the waxy corn breeding. 10 agronomic characters and fresh ear yield of 14 combinations in fresh-eat waxy corn in Southwest corn regional trial in 2012 were analyzed with grey relation grade analysis. The results showed: relational degree order of agronomic characters and fresh corn yield were as follows: row per ear > ear diameter > ear length > kernel per row > sprouting-harvest > plant height > bald tip length > kernel rate > 100-kernel weight > ear height. Row per ear was the main factor affecting fresh yield of waxy corn, and the second was ear diameter and ear length, but the ear height had less effect on yield.
