An analysis of genetic variation and divergence in Indian tropical polyvoltine silkworm (Bombyx mori L.) genotypes
The genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. The results revealed that the single shell weight showed higher genetic variation such as PCV% (17.20%), GCV% (12.93%), and heritability (56.5%) followed by single cocoon...

The genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits.

The genotype Pure Mysore was included in isolated cluster indicates its longer adaptation.
