| 摘 要： | 本文通过双列杂交和品种比较试验 ,研究了对生玉米与互生玉米产量的构成因子及其遗传效应的差异。结果表明 :对生玉米的穗长、行粒数和单株产量极显著高于互生玉米 ;对生玉米的穗粗、穗行数和千粒重与互生玉米无显著差异。影响对生玉米和互生玉穗长、穗行数和单株产量的随机因素主要是加性效应 ;其遗传率达显著或极显著水平。在主要产量性状中 ,穗粗、千粒重和单株产量的广义遗传率高于互生玉米

| Abstract: | Difference of yield characters between oppositifolious and alternative maize was analyzed in the paper.The results indicated that ear length,kernel per row and yield per plant in oppositifolious maize was higher significantly than alternative,According to the results of dillel analysis of 6 quantitative characters ,the heritability in narrow sense of grain,yield per plant was largest in oppositifolious or alternative maize.The heritability in broad sense of grian,yield,1000 kernel weitght,Axis diameter in oppositifolious maize was ,respectivel,79.30%,77.69%,77.40%,which were all higher than that alernative. |
