Cuminum cyminum, Genetic divergence, D2Abstract
Cumin (Cuminum cyminum L.) is an important seed spice crop having high cash value.The genetic improvement for yield and biotic stress resistance is the major challenge in the crop. The extent of genetic diversity observed in the genus is low, even though it is essential to evaluate the extent of diversity available in the germplasm. Hence a set of 19 genotypes were tested for the diversity index using D2 technique over yield and nine morphological traits which were observed during 2009–10 and 2010–11. All the genotypes grouped into only two clusters, showing narrow genetic base. Primary branches contributed maximum to the genetic divergence, followed by yield/plot.Downloads
