Comparative efficacy of pedigree selection and selective intermating in greengram (Vigna radiata (L.) Wilczek)

Selective intermating and pedigree selection methods were applied simultaneously to highly heterogeneous and heterozygous base populations of greengram in order to compare their relative efficacy in terms of evolving the number of productive lines as well as their production potential. Selection after two cycles of selective intermating was found to be a better method than traditional pedigree selection. The demerits of pedigree selection and merits of selective intermating are discussed. It is suggested that selective intermating replace the widely adopted but less effective pedigree selection for generating promising new material in such autogamous crops as greengram.
