Agricultural pests have caused serious economic damage to production and quality of crops. The use of crops resistant to pests is the most economic and efficient measure in controlling pests. Germplasm resources resistant to pests is the base of breeding resistant varieties. At present, studies on crop germplasm resources resistant to pests included collecting, identification, evaluation, preservation, utilization of resistant accessions and germplasm enhancement which promote the discovery and utilization of resistance genes and breeding of resistant varieties.
