大豆种子泥膜蔓生性和种皮色的遗传及其与蛋白质含量的关系

本文应用6个种间杂交组合研究了种子泥膜、种皮色和蔓生性的遗传以及它们各自与籽粒蛋白质含量的相关。结果表明:种子泥膜的遗传存在基因互补作用,蔓生性是数量性状;种皮色遗传较复杂。种子泥膜和种皮色基本上与籽粒蛋白质含量无关;蔓生性与蛋白质含量有一定相关。

THE INHERITANCE OF VINING GROWTH HABIT, SEED COAT COIORAND BIOOM ON SEED COAT AND THEIR RELATIONSHIP WITH SEED PROTEIN CONTENTS IN SOYBEANS

Six interspecific crosses of soybeans was used in this experiment. The objective of the investigation is to study the inheritance of vining growth habit, seed coat color and bloom on seed coat and their relationship with seed protein content.The results show that complementary genes control the inheritance of bloom on seed coat. The genetic constitutions of the cultivars and lines studied are proposed as follows.Dongnong 4 (G. max) B1B1B2B2b3b3Dongnong 33 (C. max) B1B1B2B2b3b3Ji-50192 (G. soja) B1B1B2B2B3B3Long 79-4004 (G. gracilis) B1B1b2b2B3B3The results also show that the vining growth habit is a quantitative character; the inheritance of seed coat color is complicated and it is controlled by more genes than those suggested by many scientists; bloom on seed coat and seed coat color are almost not correlated with seed protein contents; vining growth habit is slightly correlated with seed protein contents.
