Study of Genetic Divergence in Horsegram (Macrotyloma Uniflorum L.)

The experiment was conducted to collect the basic information on genetic divergence, genetic parameters of variability and correlation coefficient in characters under study among 88 Horsegram genotypes and was laid out in a completely randomized block design with three replications. The analysis of variance revealed highly significant differences among genotypes for all the traits. The phenotypic coefficient of variation (PCV) was higher than that of genotypic coefficient of variation (GCV) and found to be high to moderate for all traits except for days to 50% flowering. Study of genetic divergence revealed the existence of wide diversity among the genotypes studied. On the basis of the results obtained, these 88 genotypes were grouped into ten clusters. The varieties belong to clusters VIII and IX having greate statistical distance may be selected for hybridization programme as they are expected to produce good segregants.
