Abstract:

Late leaf spot caused by Phaeoisariopsis personata is the most important disease on groundnut worldwide. Although fungicide treatment is effective, it is uneconomical to use because of high cost, hazardous to environment and insensitivity build up in pathogen. The deployment of resistant cultivars is a better option to control LLS disease in groundnut the investigation was undertaken to determine the mode of genetic inheritance of LLS resistance in two F2 and F3 segregating populations of groundnut. F2 and generation of two cross TG76× GPBD5 and TG76 x ICGV 86699 were sown at MARS, Dharwad in summer and kharif 2016 were resistant under natural as well as artificial epiphytotic screening conditions. The two populations segregated in 3S:1R ratio in F2 and 1:2:1 in F3 generation. Rust resistance. The data had good fit to mendelian inheritance pattern of single recessive gene governing LLS.
