Abstract

Inheritance of growth habit, photoperiod sensitivity, pigmentation on stem and petal in lablab bean was studied. Monogenic control of growth habit was revealed from different F2 segregating families derived from the crosses between determinate and indeterminate accessions. Although the determinate character seemed to be controlled by one locus from the crosses between wild and determinate types, inheritance of the growth habit could not be clarified because of the appearance of extreme dwarf plants and determinate plants with indeterminate lateral shoots. From the same cross photosensitivity and pigmentation on stem displayed to be governed by respective two loci. This is the first report on complementary gene control of photoperiod sensitivity in lablab bean. From the crosses between determinate and indeterminate types pigmentation on stem was controlled by three loci. Petal color was observed as governing by two loci; complementary gene action.
