Genetic divergence in forage cowpea



Genetic divergence in forage cowpea



Journal of Maharashtra Agricultural Universities 16(2): 167-169



A quantitative assessment of genetic diversity for eight forage yield characters among sixty-four strains of cowpea (Vigna unguiculata (L.) Walp.) by D2 statistics showed that there is a substantial genetic diversity between the strains with D2 values ranging from 1.26 to 327.86 and inter cluster distances (D) ranging from 5.30 to 16.61. These sixty-four genotypes were grouped into six clusters. The clustering patterns revealed that genetic divergence is not necessarily associated with geographical diversity in this crop. The hybridization programme on the basis on inter cluster divergence and cluster means for the characters studied has been suggested.
