摘要
以8个花生品系配制的4×4不完全双列杂交组合的F4∶5家系为材料,研究了单株果重、仁重、结果数、饱果数、百果重、百仁重和出仁率等7个产量性状的配合力。结果表明,这些产量性状都是以加性效应为主,多数性状还存在非加性效应;母本963-4-1的单株果重、单株仁重、单株果数、单株饱果数和出仁率的一般配合力(GCA)均最高,特殊配合力(SCA)方差则是904-79最高;父本中花8号单株果重和单株仁重最高,综合表现较好;组合904-79×中花8号的产量具有较高的SCA;大多数的优良F4∶5家系来自上述3个亲本间的组合。亲本在F4∶5家系表现出的GCA与早世代不一致,花生家系品种的选育应考虑亲本GCA在多个世代的综合表现。
The combining ability of seven yield traits were analysed with the F4： 5 lines of 16 combinations by 4×4 incomplete diallel crossing. The variation of all traits among female parents and four traits, pods and seeds weight per plant, 100-pod and-seed weight among male parents were significant at 1% probability level, and shelling percentage of male parents was significant at 5% probability level. The general combining ability （GCA） of 963-4 -1 and the special combining ability （SCA） variance of 904-79 among the maternal lines were the highest on pod and seed weight per plant, pods and mature pods per plant and shelling percentage. And the GCA of Zhonghua No. 8 was the highest on pods and seeds per plant among the male parents and it＇s other traits performed well. The combination of 904-79×Zhonghua No. 8 had the bigest SCA. The majority of high yielding lines which significantly over -yielded Tianfu No. 9 was derived from 963-4-1×or 904-79×Zhonghua No. 8. It was noticed that GCA or SCA of the lines in F4：5 lines were inconsistent with these detected at earlier generation, therefore the overall performance of parental lines in several generations should be considered in peanut variety improvement.
