Abstract:
The experiment on sixty genotypes including four check varieties (G-50, G-41, G-282 and Punjab Garlic) of garlic (Allium sativum L.) was conducted to work out the genetic divergence, and cluster analyses of their various attributes on yield per plant. The maximum bulb yield per plant was observed in NDG-26 (29.97 g) followed by NDG-41 (29.30 g) and NDG-5 (28.22 g) against the general mean 23.40 g. While the minimum bulb yield per plant was recorded in NDG-31 (15.13 g). In the present study, genotypes are divided into eight clusters. Cluster I had maximum number of genotypes followed by clusters II, cluster V, cluster VIII, cluster III, cluster IV, cluster VII and cluster VI. The maximum intra-cluster D2 value observed in cluster IV. The maximum inter-cluster distance was observed between cluster VII and cluster VIII. The cluster I showed highest mean for number of cloves per bulb and cluster IV showed highest mean for weight of clove. A per cent contribution showed that plant height was found for highest contribution followed by length of leaf, number of cloves per bulb and total soluble solids for total divergence among the available genotypes of garlic.
