The extent of genetic diversity in different genotypes of potato

The maximum genetic divergence for quality characters (3145.78) was observed between cluster-I and III. The highest cluster mean values for growth characters viz. shoot girth, plant height and yield (q/ha) were observed in cluster-II. While for quality characters cluster-I showed maximum cluster mean for protein content, nitrogen content, phosphorus content and specific gravity. Cluster VII showed maximum cluster mean value for specific gravity. The characters viz. plant height, leaf area, tuber weight, number of stolen per hill and number of tuber per hill contributed maximum towards diversity in descending order. There is no parallelism between geographical and genetic divergence. Thus, based on the findings of present investigation it can be concluded that good diversity and variability was present in the genotypes tested
