GENETIC DIVERGENCE IN RAPE MUSTARD

Published on

Nineteen strains of rape mustard (Brassica campestris L.) were grouped into five clusters
using 0
2 statistic. Cluster I was the largest, consisting of two-thirds of the total population.
Cluster III showed maximum genetic distance from cluster IV, suggesting wide diversity
between them. Test weight, days to maturity and seed yield were the highest contributors
to
0 2 values. Strains Pusa Bold and Pusa Barani of cluster III and NOT 8503 of cluster IV
were found important for varietal improvement programme on the basis of their genetic
distances and higher cluster mean values for the aforesaid three characters.
  

Keywords: Genetic divergence, D2 statistic, rape mustard.
