Heterosis for Some Morphological Traits in Mungbean (Vigna radiata (L.) Wilczek)

Abstract

Heterosis over mid, better and top parent values for some important morphological traits (node of the first pod peduncle, nodes on the main stem, no. of pod clusters on the main stem, average internodal length) were estimated in 15 cross combinations derived from a half diallel involving 6 diverse mungbean genotypes. The low extents of heterosis effects were observed for node of the first pod peduncle and average internodal length in the existing mungbean germplasm. The cross combinations having ML-5 as one of the parent may produce segregates with yield potential through more number of pod clusters on main stem. The hybrid VC 3902A x ML-5, which produced high heterotic effects for nodes on main stem and pod clusters on main stem is suggested for exploitation for developing high yielding mungbean varieties.
