Adaptability and Phenotypic Variations of Agronomic Traits in Common Bean Germplasm Resources in Different Environments
摘要
Abstract
This study aimed at evaluating the phenotypic variation and environmental adaptability of common bean (Phaseolus vulgaris L.) germplasm resources.Twelve traits of 686 accessions of common bean were assessed in Harbin of Heihongjiang province,Nanyang of Henan province,Bijie of Guizhou province and Ledong of Hainan province in 2014-2015.The results showed that Ledong was the best location for the reproduction of germplasm resources from South America and Bijie was the best location for the reproduction of Chinese germplasm resources.There were large variations in the 12 traits among the 686 common bean germplasm resources and the average (across locations) coefficients of variation ranged from 8.11％ of growth duration to 70.83％ of plant height.Hundred-seed weight showed the highest heritability of 0.73,whereas days from sowing to flowering showed the lowest one of 0.01.The correlation and path analysis revealed that number of pods per plant was the most important factor affecting the yield per plant.Two hundred and eighteen specific germplasm resources were identified with dwarf,large-seed,and early maturity and so on,among which nine had three favorable traits and 53 had two favorable traits simultaneously.关键词
