Description Sterility mosaic disease (SMD) caused by Pigeonpea sterility mosaic virus and vectored by the eriophyid mite is a serious disease of pigeonpea in almost all pigeonpea-growing areas. In this context, total 976 Pigeonpea genotypes including germplasm accessions and breeding lines was evaluated for SMD resistance under artificial epiphytotic conditions in a disease nursery at ICRISAT, Patancheru during 2003/2004. Based on this evaluation, a set of 166 Pigeonpea genotypes with high levels of SMD resistance was selected and again evaluated for 3 years during 2004/2005–2006/2007 in a disease nursery at Patancheru. Finally, a Pigeonpea Sterility Mosaic Disease Nursery (PSMDN) of the 28 genotypes with the most resistance against SMD was established for multi-environment evaluation. At Bangalore, Dholi and Rahuri locations, all genotypes were susceptible to SMD with mean disease incidence of 71.1, 50.4 and 32.6 % respectively. However, most of the genotypes were resistant at four locations, Akola, Badnapur, Patancheru, and Vamban, and moderately resistant at Coimbatore. The GGE biplot analysis explained about 67.26 % of total variation and identified four genotypes (ICPLs 20094, 20106, 20098, 20115) as the most stable and resistant to SMD.
