以性状多样的长豇豆为材料 ,对其荚色、籽粒色和生长习性进行遗传分析。结果表明 :籽粒色的相对性状间均表现 1对等位基因差异的遗传 ,黑籽对红籽为显性 ,黑籽对白籽、红籽对白籽均为显性 ,花斑籽对红籽为显性。生长习性由 2对等位基因控制 ,其中蔓生对矮生为显性上位性。荚色因材料不同有的表现为质量性状 ,且紫荚对浅绿荚为显性、浅绿荚对绿荚为显性、白荚对浅绿荚为显性 ;有的表现为数量性状 ,即由多基因控制。 With the characteristics of a variety of long cowpea as a material, its pod color, grain color and growth habit of genetic analysis. The results showed that all the relative traits of grain color showed the inheritance of one pair of alleles. The black seed was dominant to red seed, the black seed to white seed and the red seed to white seed were both dominant. Dominant. Growth habit is controlled by two pairs of alleles, of which dwarf is dominant. Pod color due to different materials and performance of some of the quality traits, and the purple pod for the light green pod dominant, light green pod dominant for the green pod, white pod for the light green pod domineering; some performance of quantitative traits, That is controlled by multiple genes.
