Abstract: Flower and pod abscission rate and pod number per plant are two key factors that influence plant yield in soybean.A F2 population of 100 plants derived from a cross between cultivar Jiyu 73 and Tiejiasilihuang,both of which have contrasting flower and pod abscission rates.A genetic linkage map of soybean was constructed,that consisting 34 linkage groups covering 1351.5 cM.The multiple-QTL models (MQM) was used to identify quantitative trait loci (QTL) associated with flower and pod abscission rate and pod number per plant.Two QTLs were identified for flower and pod abscission rate on the same chromosome 16 (GM16) and their genetic contribution rates were 10.9% and 9.7%,respectively.Five QTLs for pods number per plant were detected on chromosome GM02,GM07,GM10,GM04 and GM05,respectively.The genetic contribution rates were from 8.8% to 15.9%.The results obtained in this study will be useful for further fine mapping,gene cloning and marker assisted selection of these traits.
