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。
F4: 5 pedigrees with 4 × 4 incomplete diallel cross combinations of 8 peanut lines were used as materials to study the effects of single fruit weight, kernel weight, fruit number, fruit number, fruit weight, Kernel rate and other 7 yield traits with the combining ability. The results showed that most of the yield traits were additive effects, and most of the traits still had non-additive effects. The fruit weight per plant, kernel weight per plant, fruit number per plant, The GCA of fruit number and kernel rate were the highest while the SCA variance was the highest among 904-79. The fruit weight per plant and the kernel weight per plant of the parent flower Zhong 8 was the highest, Good; the combination of 904-79 × Zhonghua 8 had higher SCA; most of the excellent F4: 5 lines came from the combination of the above three parents. The parental GCA exhibited in the F4: 5 pedigree was inconsistent with the earlier generation, and the breeding of the peanut pedigree should take into account the overall performance of the parental GCA over multiple generations.
