Pigeonpea is the most important pulse crop in India. Pod fly, Fusarium wilt and sterility mosaic disease are the major biotic constraints in pigeonpea production. On Farm Trials were conducted on wilt and sterility mosaic disease resistant pigeonpea variety LRG-105 against LRG-41 variety during the year 2019 and 2020 in Chittoor district of Andhra Pradesh. LRG-105 variety was released from Acharya N G Ranga Agricultural University, Guntur, Andhra Pradesh under the name Krishna during the year 2019.

During kharif 2019, 6.38% and 3.42% of sterility mosaic incidence was observed in LRG-105 and LRG-41 respectively whereas during kharif 2020, 5.86% and 5.3% of disease incidence was recorded. Redgram variety LRG-105 recorded an average yield of 409kg/ha and 371kg/ha during 2019 and 2020 respectively whereas LRG-41 recorded 198kg and 158kg per hectare. Rainfall during flowering stage affected crop yield during the year 2020 in both the varieties.
