摘　　要：本文应用粒形指数对24个组合的亲本F_1和F_2代进行了研究,结果表明,不同粒形指数品种杂交的F_1代,其粒形指数介于双亲中值。F_2代粒形指数表现出中心对称的数量性状的分布特征,估算出粒形指数的广义遗传传力(h^2B％)为50—73.1％。The study was conducted by using seed shape index for F1, F2 and their parents involving 24 crossing. The result indicated that the seed shspe index of F1 hybrids derived from crosses between different seed shape index varieties was a mid - parent value of both parents. The F2 populations performed a normal distribution feature of quantitative character. The broad-sense inheritability
