"Late leaf spot and rust diseases occur together and cause considerable yield loss in groundnut.\r\nCultivation of resistant varieties is the best strategy to stabilize productivity under disease epidemics.\r\nSeveral varieties resistant or moderately resistant to LLS and rust have been developed in groundnut, but\r\nmost of them differ in yield loss even at the same level of disease due to complex interrelationships\r\nbetween disease and yield loss. Crop loss models have been employed to gain insight into these\r\nrelations and to plan sound breeding strategies. In the present study, different empirical models were\r\ntested for their explanatory value for yield loss among 10 groundnut genotypes with varying level of\r\nresistance to late !eafspot and/or rust. Towards yield loss modeling, disease severity at different growth\r\nstages and physiological traits viz., leaf area index (LAI), harvest index (HI), healthy leaf area duration\r\n(HAD), crop and pod growth rates(CGR and PGR) and partitioning coefficient (PC) were considered as\r\nindependent variables, while yield loss as dependent variable in regression models.\r\nSingle pOint models based on disease did not explain the variation in loss completely, but revealed pOd\r\nfill ing as the critical stage in determining yield loss. Multiple point models using disease at different stages\r\nmarginally improved the explanatory value; Inclusion of physiological traits in stepwise regression models\r\nimproved the R2 considerably, revealing their relevance to yield loss. Yield loss varied significantly among\r\nthe genotypes resistant to both LLS and rust (9-17%), moderately resistant to LLS or rust (18-26%) and\r\nsusceptible to LLS and rust (30-42%). Resistant genotype, GPBD-4 had high yield potential with minimum\r\nyield reduction due to Its high partitioning efficiency and pod growth rate. Though highly susceptible,\r\nTAG-24 showed tolerance by early cessation of vegetative growth and efficient translocation of\r\nphotosynthates to pOds leading to high harvest index."^^ .
