Abstract

The cultivated pigeon pea (Cajanus cajan) is one of the most important source of protein for worlds marginal and vegetarian population. Sterility mosaic disease (SMD) also known as “green plague of pigeonpea” is one of the severe threats in pigeon pea production causing severe yield loss. Keeping this in view, identification of SMD resistant cultivars with better understanding of inheritance of disease were key consideration for the present study. RILs were screened for SMD resistance with leaf stapling technique at Green house, IBT, PJTSAU during Kharif 2012 and 2013. RILs showed digenic ratio (9S:7R) for SMD resistance, indicating complementary gene action which showed dominance of susceptibility over resistant and based on the per cent disease incidence, the RILs could be broadly classified as resistant (PDI <20%) and susceptible (PDI >20%).The SMD incidence among the 188 RILs ranged from 0 to 100% whereas, the susceptible parent (ICP 8863) showed mean value of 79.17% and resistant parent (ICPL 20097) showed it as 0%. Out of total 188 RILs screened, 90 RILs showed resistant reaction to SMD infection while 98 RILs were susceptible. 33 RILs were identified as resistant lines which consistently showed 0% PDI during screening for both the years.
