ABSTRACT

Genetic divergence among twenty eight bottle gourd (Lagenaria siceraria) genotypes was estimated using D2 and Canonical analysis. The genotypes were grouped into five clusters. The maximum intercluster distance was between cluster III and cluster I, and the minimum was between cluster IV and II. .The crosses between the genotypes LS001, LS002, LS007, LS010, LS013, LS016, LS017, LS028 of cluster II and LS018, LS023 in cluster V would exhibit maximum heterosis and produce new recombinants with desired traits in bottle gourd.

 Key words: Lagenaria siceraria, genetic divergence, cluster and canonical analysis
