| 摘 要： | 以20份早熟欧美血缘自交系为供试材料,9份SS群自交系为母本、11份NSS群自交系为父本,采用不完全双列杂交设计,进行配合力分析评价。结果表明,自交系DNF342、DNLM18、东407、东409和东401产量一般配合力(GCA)优良,东304和东503株高、穗位高一般配合力优良,有利于降低杂交组合株高和穗位高。杂交组合东407×东601、东409×DNF342、东502×DN4206、东409×东305、东407×DN4206和东401×东601产量对照优势较强,可用于新品种试验。

| Abstract: | This study used 20 early-maturing inbred lines from European and American, including 9 SS-group inbred lines as female parents and 11 NSS-group inbred lines as male parents. The incomplete diallel cross design was used to evaluate the combining ability. The results showed that DNF342, DNLM18, Dong407, Dong409 and Dong401 had good yield general combining ability(GCA), while Dong304 and Dong503 had good plant height and ear height GCA, which were beneficial to reduce plant height and ear height of hybrid combinations. The hybrid combinations Dong407×Dong601, Dong409×DNF342, Dong502×DN4206, Dong409×Dong305, Dong407×DN4206 and Dong401×Dong601 had strong yield comparative advantages, which could be used for new variety experiments. |
