Implications of genetic diversity in the improvement of silkworm Bombyx mori L.

ABSTRACT Improvement programs depend on characterizing genetic resources, this process being the fundamental basis for determining the diversity and genetic divergence of such resources and thereby enabling a rigorous, efficient selection of the parentals that, through hybridization, will go on to e...
