摘要

遗传变异对育种计划的收益至关重要。后代重组的循环过程是提高选择更好的基因型组合的机会的一种策略。本研究的目的是在根系性状的第一次循环选择中,确定普通豆类基因群之间的优势后代。安第斯和中美洲基因群的亲本在完全双列杂交方案中杂交。随后,将亲本和F1、F2群体进行田间种植。为了建立循环选择的基础群体(C0),选择7个根系表现较好的分离群体(F2)进行杂交,形成重组后代(C1)。为了估计选择增益,将亲本与C0和C1基因型在以下变量上进行比较:总根长(TRL, cm)、根投影面积(PRA, cm2)、根体积(VOL, cm3)和根尖数(RT)。基因型组合之间的差异表明存在遗传变异和循环选择的有效性。在第一个重组周期中,根系相关性状的平均遗传进展分别为12.9% (TRL)、12.6% (PRA)、12% (VOL)和11.5% (RT)。7个C1后代的根系性状的平均表型表现均超过其亲本。这些后代很有希望成为下一个选择周期的基础种群。

Identification of superior progenies between common bean gene groups for root system obtained by recurrent selection
Genetic variability is essential for gains in breeding programs. The cyclic process of progeny recombination is a strategy to raise the chances of selecting better genotype combinations. The objective of this study was to identify superior progenies between common bean genes groups in first recurrent selection cycle for root system traits. Parents of the Andean and Middle American gene groups were hybridized in a complete diallel scheme. Thereafter, the parents and F1 and F2 populations were planted in the field. To establish the base population of recurrent selection (C0), seven segregating populations (F2) with superior performance for root system were selected and intercrossed, resulting in recombinant progenies (C1). To estimate the selection gain, the parents and C0 and C1 genotypes were compared with regard to the following variables: total root length (TRL, cm), projected root area (PRA, cm2), root volume (VOL, cm3) and number of root tips (RT). The difference between genotype combinations indicates the presence of genetic variability and effectiveness of recurrent selection. The mean genetic progress for root system-related traits was 12.9% (TRL), 12.6% (PRA), 12% (VOL) and 11.5% (RT) in the first recombination cycle. The mean phenotypic performance of seven of the C1 progenies exceeded that of their parents for all root system traits. These progenies are promising as base populations of the next selection cycle.
