【摘要】 对15个菜用大豆品种鲜荚采摘期的农艺性状及品质性状的遗传潜力进行了研究。相关分析表明:鲜百粒重与荚宽,单株粒数与单株荚数,地上部生物学产量与鲜荚产量、鲜粒质量,鲜荚产量与鲜粒质量,单株荚数与地上部生物学产量间呈显著正相关。鲜籽粒脂肪含量与地上部生物学产量、鲜粒质量间呈显著负相关。鲜百粒重、鲜籽粒蛋白质含量的遗传力相对较高,单株产量的遗传变异系数较大,鲜荚产量和单株产量的遗传进度最大。更多还原

【Abstract】 Hereditary potency of agronomic characters and nutritional characteristics were analyzed according to 15 vegetable soybean varieties at the podding stage. The correlative analysis showed significant positive correlation between 100-fresh seed weight and pod width, number of seeds per plant and that of pods per plant, yield of biomass and that of green pods, yield of biomass and that of fresh seeds, yield of green pods and that of fresh seeds, number of pods per plant and yield of biomass. It was significant negative correlations between fat content of fresh-seed and yield of biomass, and yield of fresh seeds.The hereditary potency of 100-fresh seed weight, and protein content of fresh seeds were higher than that of the other characteristics. Genetic variation of yield per plant was large. Fresh-pod yield and seed yield per plant showed most hereditability.更多还原
