Inheritance of the Traits – Seed’s Color and Plant Habitus, in Phaseolus vulgaris L. Cross

A study to establish the inheritance of the traits color of seeds and plant habit, in common bean cross BAT 477 x Dobrudjanski ran, was conducted. It has been found that in the F1-generation were exhibited dominant traits - brown seeds, purple color and III-a type of habitus. In F2-generation the disruption by the coloration of flowers was in ratio 3 purple : 1 white (0,50 0,20). The ratio of disruption by the traits brown : beige seeds (0,20 0,10) and brown : white seeds (0,50 0,20) was also 3 : 1, while beige : white seeds was 1 : 1 (0,90 0,50). The ratio of disruption by the trait type of habitus was also 3 : 1 (ІІІ-а : ІІІ-b type), (0,900,50). A monogenic control of studied traits was found. Brown and beige colors of seeds are probably controlled by different alleles of the same gene. It was established that traits color of flowers and color of seeds are relatively inherited
