| 摘 要： | 利用玉米单株产量耐密系数分析玉米单交种的耐密性,并对单株产量耐密系数与植株和穗部性状的相关性进行分析。结果表明:耐密系数可作为初步评价玉米单交种耐密性的参考依据。选育耐密品种时,应选择有效穗长、穗行数和出籽率这3个性状在不同群体比较稳定和株型收敛的玉米品种,但是植株和穗部的选择不能完全代替耐密性的选择,品种抗病性和抗逆性起着举足轻重的作用。

| Abstract: | Close-planting resistance of maize hybrids was analysed by close-planting resistance coefficient of the pre plant yield,and close-planting resistance coefficient and agronomic characteristics were made correlative analysis. The results showed that close-planting resistance coefficient was a reference baseless on close-planting resistance of maize hybrids.When selecting close-planting resistance maize hybrids,the maize hybrids whose effective ear length,ear row,shelling percentage were steady in the different groups were seleced.But agronomic characteristics were not the whole,disease resistance and adversity resistance were important. |
