Sorghum germplasm from Thailand showing resistance to sugarcane aphid, Melanaphis sacchari Zehntner

Abstract

Sorghum is one of the mandate crops of the International Crops Research Institute for the Semi Arid Tropics (ICRISAT), Patancheru, AP, India. Sorghum germplasm is regularly exchanged between ICRISAT and several sorghum growing countries in Africa, America, Asia, and Europe. The ICRISAT gene bank through National Bureau of Plant Genetic Resources (NBPGR) imports the sorghum germplasm after necessary quarantine processing. The germplasm, after processing in the laboratory, is transferred to the post- entry quarantine isolation area (PEQIA) to ensure that only insect and disease free germplasm enters into India and the ICRISAT gene bank
