大豆生理性状的遗传研究

GENETIC STUDY ON THE PHYSIOLOGICAL CHARACTERS OF SOYBEAN

用65份有代表性的大豆品种资源,研究了10个生理性状的遗传变异及其与籽粒产量的关系。结果表明,大豆生理性状遗传变异丰富,多数性状遗传力较高,预期遗传进度可观。可将遗传力高,与产量相关密切的生理性状作为产量间接选择的指标。

Sixty ?five soybean varieties were used to study the genetic variance of tea physiological characters and the relationships between them and seed yield. The results showed that the generic resources of physiological characters of soymean in Anhui were abundant,and the major physiological characters had high heritability and large expected genetic advance. Some physiological characters with high heritability and colsely related to seed yield might be the useful characters for indirect selection of soybean seed yield.
