Abstract:
A field experiment was conducted during Rabi season of 2021 at College of Horticulture, Rajendranagar, Hyderabad to estimate the genetic diversity of onion. Forty genotypes of onion were evaluated for ten characters in a randomized block design to study the genetic divergence. D2 statistic indicated that the genotypes studied were genetically diverse. Based on D2 values, the genotypes were grouped into twelve clusters. The maximum inter cluster D2 value of was observed between cluster Ⅷ and Ⅶ (150.67) followed by cluster X and Ⅷ (149.97), while the lowest was between cluster Ⅲ and Ⅱ (13.56). Cluster Ⅷ showed maximum intra cluster diversity followed by cluster Ⅴ.

Cluster Ⅷ showed maximum intra cluster diversity followed by cluster Ⅴ.
There were seventeen genotypes in cluster І, six genotypes in cluster Ⅴ, five genotypes in cluster Ⅷ, four genotypes in cluster Ⅳ and the cluster Ⅱ, Ⅲ, Ⅵ, Ⅶ, Ⅸ, Ⅹ, Ⅺ and Ⅻ contained solitary genotype. D2 analysis suggested that 1770, 1774, Bhima Shwetha, W-125 and 1772 were the most diverse parents. These genotypes could be utilized as parents in breeding programme to enhance the productivity of onion.
