夏大豆瘪荚率的遗传分析
Genetic Analysis on Useless Pod Rate of Summer Soybean
摘要
Abstract
The phenomenon of pods without peas is currently one of the major factors influencing summer soybean production in the Huanghuai Valleys. A joint segregation analysis was conducted to investigate hereditary differences of soybean varieties using the useless pod rate as an indicator. The analysis on the useless pod rate of soybean from four generations (P1,P2,F1 and F2) of three cross-combinations (Yudou 25×Zhonghuang 24,Jihuang 13× Zhonghuang 13 and Jihuang 13×Kaidou 16) showed that these five parent varieties differed significantly in the incidence of useless pod rates(6. 26% - 90. 96%). Variations of proportion of useless pod rates mainly caused by genetic factors in the three cross-combinations,and further controlled by major genes,but the major gene heritability was low, ranging from 13. 40% to 32. 42%. This study demonstrated the useless pod rate in pods without peas phenomenon was a typical quantitative hereditary trait,and the soybean breeding should converge beneficial genes through using the convergent backcross method and recurrent selection method.关键词
