Evaluation of Sorghum Lines for Multiple Disease Resistance in India uri icon

abstract

  • Twenty seven sorghum accessions/breeding lines possessing resistance to individual diseases were evaluated between 1984 and 1987 at Dharwar and Mysore (Karnataka) for downy mildew (DM), caused by Peronosclerospora sorghi, Patancheru, ICRISAT Asia Center (Andhra Pradesh) and Bhavanisagar (Tamil Nadu) for grain mould (GM), caused by a complex of Gibberella fujikuroi, Fusarium pallidoroseum, Curvularia lunata (Cochliobolus lunatus) and Phoma sorghina, Dharwar for rust (RU), caused by Puccinia purpurea, Udaipur (Rajasthan) for grey leaf spot (GL), caused by Cercospora sorghi, and Pantnagar (Uttar Pradesh) for anthracnose (AN), caused by Colletotrichum graminicola, zonate leaf spot (ZL), caused by Gloeocercospora sorghi and GL. IS 8283 and IS 8607 were resistant to all 6 diseases; IS 3547, IS 8185 and M 35610 were resistant to 4 diseases; IS 3443, IS 3546, IS 14332, IS 14387 and IS 22227 were resistant to 3 diseases and 13 genotypes were resistant to 2 diseases at all the locations. Some of these accessions are being used in crossing programmes to breed for multiple disease resistance
