GENETIC-DIVERGENCE IN GENOTYPES OF PIGEON PEA

Fifty-four genotypes of pigeon pea were characterized in Petrolina, PE , Brazil. Nine quantitave characters of bigger agronomic interest were used for determination of the genetic distance and identification of similar groups among the genotypes. The techniques utilized were: 1. c luster analysis using the euclidian distance of the original standardi zed data and the cluster Tocher method; and 2. graphic dispersion in r elation to the first principal components. The grain genotypes ICPL 6, ICP 6971; the forage genotypes D1 type, D3 type and ICP 6970; and the forage/grain genotype D2 type are recommended for use in breeding pro grams, considering not only their genetic distance but also their agro nomic performance.
