Abstract
A prerequisite for detecting sources of resistance to insect pests is to have diversified crop germplasm. Information on major sources for obtaining germplasm plays a crucial role in developing resistant crop varieties. This chapter indicates 220 sources of germplasm centres for more than 25 crop plants. Monoculture and intensive cultivation practices endanger the local germplasms, and care should be taken to conserve them. Wild species of the cultivated crops need also to be conserved. Local expertise, manpower and resources need to be best utilized for identifying resistant sources.
