| 摘 要： | 应用灰色关联度分析法,以2010年四川省鲜食甜玉米区试14个组合的10个农艺性状与鲜穗产量进行了分析.结果表明,甜玉米农艺性状与鲜穗产量关联度的大小依次为德行数＞穗长＞行粒数＞穗粗＞出苗-采收＞穗位高＞株高＞百粒重＞秃尖＞出籽率,穗行数是影响甜玉米鲜穗产量的主要因素,其次是穗长、行粒数,而出籽率对产量影响较小.

| Abstract: | 10 agronomic characters and fresh ear yield of 14 combinations in fresh-eat sweet corn region test of Sichuan in 2010 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 length>kernel per row>ear diameter>>ear height>plant height>100-kernel weight>bald tip length>kernel rate.Row per ear was the main factor affecting fresh yield of sweet corn,and the second was ear length and kernel per row,b... |
