| 摘 要： | 选取具有代表性的15个玉米自交系为试验材料,通过在两种种植密度下的表现,利用玉米单株产量耐密系数分析了玉米自交系的耐密性,并对单株产量耐密系数与产量相关性状的相关性进行分析.结果表明,15个品种中,PH6WC的单株产量耐密系数最高,达27.35,明显高于其余自交系,耐密系数较高的自交系还有郑58、K12与掖478;产量相关性状与单株产量耐密系数相关性不显著.耐密系数可作为初步评价玉米自交系耐密性的参考依据.

| Abstract: | Fifteen inbred lines of maize were planted at 2 densities.The tolerant coefficient of high density was calculated using the yield of per plant as index.The results showed that the top 4 inbred lines with high density tolerant coefficient ranked as PH6WC> Zheng 58> K12> Ye478,which of PH6WC was 27.35.The correlation between yield-related trait and high density tolerant coefficient was not significant.The tolerant coefficient of high density could be used as a preliminary reference to evaluate the tightness resistance of maize inbred lines. |
