摘要
利用NCⅡ设计,对几个玉米改良自交系主要农艺性状进行配合力及遗传参数的分析.结果表明:产量较优组合为昌7-2×MD-6、昌7-2×MD-2、四-144×MD-1.株高、穗位高、百粒重受加性基因控制,环境影响也较小,秃尖、穗粗的受非加性基因控制,环境影响较大.
In this study,the crossing pattern system followed a North caralina designⅡ(NCⅡ). The analysis showed that the chang 7-2 × MD-6、chang 7-2 × MD-2、si-144 × MD-1 were the best combinations for yield traits. It ap-peared that narrow genetic ability of plant height、ear height 100_grain weight was high,while that of battern ear tip、ear diameter was low.
