Abstract

Studies on Genetic Variability and Path Analysis of 40 genotypes in garlic revealed that wider variability was present for different traits. The genetic analysis showed that the clove weight and bulb yield per plant registered highest GCV and high heritability coupled with high magnitude of genetic advance indicating additive gene action in those characters. The path analysis also showed that clove weight and highest direct positive effect on bulb yield per plant. Thus the results sug- gested that the clove weight is the most important charector and would serve as good selection index for further improvement of garlic.
