GENETIC DIVERGENCE IN PEARL MILLET ACCESSIONS OF INDIAN AND EXOTIC ORIGIN

Published on

Fifty two pearl millet accessions of Indian and exotic origin were evaluated for genetic
divergence. The accessions were grouped in ten clusters. Cluster I had approximately half
of all the accessions. The genotypes in cluster I were early and had higher threshing ratio
and seed weight, while those in clusters IV and V showed quick early growth. The
clustering pattern indicated that the geographic diversity was not necessarily related with
genetic diversity. Seedling vigour, productive tillers and plant height have been identified
as potent variables which can be used as parameters while selecting diverse parents for
hybridization programmes.
