GENETICS OF PRODUCTIVE PEDUNCLES ON MAIN STEM AND BRANCHES IN MUNGBEAN (VIGNA RADIATA (L.) WILCZEK)

G.S.S. KHATTAK^* AND I. SAEED

Abstract: Components of genetic variation for productive peduncles on main stem and branches in mungbean were estimated using triple test cross procedure. Treatments used for estimation of genetic variation for both traits exhibited highly significant differences which indicate the existence of considerable genetic variation among inbred lines, testers and developed recombinants. Epistatic effect showed significant role in the inheritance of both traits. Productive peduncles on main stem exhibited almost equal values for both i type, and j + l type non-allelic interaction whereas i type interactions value was more compared to j + l type interactions in productive peduncles on branches. This indicated that additive x additive type non-allelic interaction plays an important role in the inheritance of productive peduncles on branches. The complex inheritance of both traits can be exploited for improvement by delay in selection until the material is advanced through bulk procedure.
