摘要： 本文研究江淮下游地区大豆地方品种产量与十六种数量性状的表型和遗传性相关,以及产量各因素相互间的表型和遗传型相关,计算产量选择指数,并讨论其育种意义。试验表明:遗传型相关一般接近或稍高于表型相关;群体产量与生育前期、全生育期、单株粒重、百粒重、茎粗、结英高度正相关,与每株粒数、主茎分枝数、倒伏性负相关;百粒

Abstract:

The objectives of this study are to investigate the pheno-typic and genotypic correlations between yield and sixteenquantitative characters,also between yield component charactersthemselves,of the local soybean varieties in lower Yangtze andHwai valleys,to estimate the selection indices of yield
