Abstract

Begomovirus infection has been reported from various important crops, including chilli pepper. The use of resistant chilli pepper cultivars is considered as the most effective way to control this disease. Study was conducted using two structured families (parental, F1, F2, back cross) derived from IPBC12 x 35C2 and IPBC10 x IPBC14, which IPBC12 (resistance), IPBC10 (moderate resistance), IPBC14 (moderate susceptible), and 35C (susceptible) to Begomovirus. Segunung isolate from Begomovirus infected plants was inoculated to the population using Bemisia tabaci as the vector. Results showed that begomovirus resistance on chili pepper was polygenic in nature, with extra chromosomal effect characterizing the IPBC12 x 35C2 family. For IPBC10 x IPBC14 family, the resistance was full dominant with additive, dominant, additive x additive and dominant x dominant gene actions, whereas for the IPBC12 x 35C2 family was over dominant with additive, dominant and additive x additive gene actions. Broad sense heritability was high on both family, but narrow sense heritability was low on IPBC10 x IPBC14 family. Therefore, recurrent selection should be considered as method for the development of hybrid cultivars with Begomovirus resistant.
