Abstract:
The genetic improvement of any crop mainly depends on the amount of genetic variability present in the population. To explore this variability, an effort was made to classify, understand the diversity among 95 rice genotypes for 27 yield and yield contributing traits using Mahalanobis D² statistics. Analysis of variance revealed a wide and significant variation for all the 27 traits studied. Divergence studies through D² statistics indicated the presence of substantial diversity by forming large number of clusters (22 clusters at Shirgaon and 20 clusters at Karjat) with wide range of inter-cluster distances.
