菜用大豆粒荚选择标准的研究

STUDY ON SELECTIVE STANDARD OF SEED PODS OF VEGETABLE SOYBEAN

通过对 1 2个菜用大豆的粒荚性状间相互关系的研究 ,提出菜用大豆专用品种二粒荚粒荚选择标准 :百粒重 2 9.72 -3 4.58g;百粒鲜重 60 .79-70 .55g;鲜百荚皮重1 3 5.89-1 61 .0 5g;百荚鲜重 2 57.4 7-3 0 2 .75g;鲜荚皮长 5.2 4 -5.98cm;鲜荚皮宽1 .4 5-1 .62 cm,在此范围内三粒荚需占 0 -52 .9%。各种类的粒荚 1 2个性状间均表现极显著的相关 ,建议以干百粒重、荚皮宽、长作为对粒荚其它性状的相关预测性状 。

Interrelationship among 12 characters of vegetable soybean seed pods was studied. Pod selective standard of two-seed pods for the special variety of vegetable soybean is of primary importance. 100-seed dry weight should be 29.72-34.58g, 100-seed fresh weight 60.79-70.55g fresh weight 100-pod rind 135.89-161.05g, 100-pod fresh weight 257.47-302.7g, the length if fresh pod rind 5.24-5.98cm and the width 1.45-1.62cm. The breeding strategy is to select large seeds or more seeds in a pod of vegetable soybean. According to the relation and regression coefficient of all characters, parameters of the selective standard and ten linear equstions were made for seed pod characters of vegetable soybean. In is suggested that 100-seed dry weight, pod width and length are regarded as relative calculation characters to others, that is the analysis of 100-seed dry weight as calculating the theoretical yield of vegetable soybean.
