Abstract: An experiment was conducted during 2016-2017 at Vegetable Research and Demonstration Block of college of horticulture, VCSG Uttarakhand University of Horticulture and Forestry, Bharsar. The experiment was laid out in a Randomized Block Design (RBD) with three replications. Six diverse chilli lines viz. Byadgi Dabbi, Byadgi Kaddi, Arka Lohit, Arka Suphal, G-4 and Pant C-1 used as parents and were crossed in a diallel fashion (excluding reciprocals) to obtain fifteen cross combinations along with one check cultivar Arka Harita. Totally 22 genotypes were evaluated for the estimation of combining ability using six parents. The analysis revealed that parents and crosses differed significantly for general and specific combining ability effects. The relative magnitude of gca variances was higher than the sca variance, indicates the role of additive gene action component in the expression of all the traits. The parents Byadgi Dabbi for average fruit weight. Arka Lohit for fruit diameter, number of fruits /plant, fruit yield per plant and fruit yield per plot were found to be the best general combiner. The crosses Arka Lohit × Arka Suphal and Arka Lohit × Pant C-1 were the best specific crosses for green fruit yield and its contributing traits and can be further utilized commercially in crop breeding programme for the improvement of yield characters in chilli.
