Abstract: Viruses are common plant diseases that cause production and quality loss in the chilli crop. The major reasons responsible for low productivity in chilli include adverse climate, poor quality seeds, diseases, and high incidence of pests. Among the diseases, Chilli leaf curl complex disease is one of the destructive diseases of chilli, which is mainly transferred by chilli whitefly (Bemisia tabaci) causing considerable yield loss. Effective control of leaf curl disease using chemicals is difficult and uneconomical and also the chemical residues may affect the health of the consumer. Therefore, use of tolerant genotypes/varieties is the simplest and more convenient method of virus control. Hence, developing high yielding genotypes tolerant to major viruses is of paramount importance. The present investigation was carried out to evaluate the chilli genotype resistance for leaf curl virus disease during 2019. A total of 59 genotypes were evaluated for leaf curl virus in two seasons and the field experiment was carried out in randomized block design with two replications. All the genotypes used in experiment were studied for yield, quality along with tolerance to the leaf curl disease. Lesser incidence of leaf curl virus was recorded in the genotypes PLR-1, CA-141 and F-5 with 12.97, 14.54 and 15.45% respectively. Among the genotypes evaluated during both the seasons, the genotypes CA-7, CA-116 and F-410 were found to be promising based on yield with moderate resistance to leaf curl viral disease. Therefore, these lines can be used in further breeding programmes.
