- 摘要:
- 核心选样是在核心种质基础上提出的实用性概念,指围绕综合育种目标建立的核心材料库,供育种者选用。以我国菜用大豆主产区154个代表性地方品种为材料进行2次重复的随机区组试验,依据荚长、荚宽、荚厚、百荚鲜重、百粒鲜重、单荚粒数和可溶性糖等感官品质性状进行聚类分析,采用欧氏距离计算遗传材料间的遗传距离,并用离差平方和进行聚类,根据树型图与方差分析,选出优良级别的2类,构建了由47个品种组成的夏播菜用大豆感官品质性状核心选样。将从代表性地方品种中单一性状优选的品种与从核心选样优选的品种作比较分析,表明从核心选样中选择的品种具有较多综合优良性状。
- Abstract:
- Core selection means a selected germplasm collection related to comprehensive breeding target traits,which is an applied concept based on “core collection”.The representative 154 landraces of summer-planted vegetable soybeans from major producing area in China were chosen and tested in a randomized block design with two replications.The pod length,pod width,pod thickness,100 fresh pod weight,100 fresh seed weight,number of seeds per pod and soluble sugar content were evaluated.Their phenotypic values were calculated for Euclidean distances among accessions,and then the Ward’s method of hierarchical cluster was used for cluster analysis.According to the dendrogram and analysis of variance (ANOVA),the core selection composed of 47 landraces was established through choosing the two groups with better performances.The results showed that the landraces chosen from the core selection could retain comprehensively better traits than those from single elite traits.
