Multifoliate leaf mutants of mungbean and urdbean

Full text: Both mungbean (Vigna radiata (L.) Wilczek) and urdbean (Vigna mungo (L.) Hepper) are characterized by trifoliate leaves. In the M2 of mungbean cultivar 'Pant Mung-2' after treatment with 40 kR gamma rays a mutant was identified in which each leaflet is substituted by a trifoliate leaf, giving 9 or even more leaflets. The mutant was established as a true breeding line. The character is controlled by a single recessive gene which was designated mf1. In urdbean, the same type of mutation was detected in the M2 of the cultivar 'Netiminumu' after treatment with 50 kR gamma rays. Also this mutant character (designated mf1) shows monogenetic recessive inheritance. (author)
