Abstract

During 1978-83, 88 pigeon pea lines resistant to sterility mosaic (SM) from different research centres in India were tested at 10 locations (Badnapur, Bangalore, Dholi, Pantnagar, Faizabad, Kanpur, Ludhiana, Patancheru, Vamban and Varanasi) to identify lines with stable and broad-based resistance. The multilocation evaluation was carried out through the joint Indian Council of Agricultural Research and the ICRISAT Uniform Trial for Pigeon Pea Sterility Mosaic Resistance. SM resistant genotypes were identified at each of the 10 locations. Lines ICP 7867, ICP 10976 and ICP 10977 were resistant or tolerant at all 10 locations. These lines are now being used by breeders at ICRISAT as well as in the Indian national programme for developing SM resistant and high yielding cultivars.
