Commercially plant breeding and crop improvement is possible to know heterotic behavior of plant species and heredity of the traits. It is commonly accepted that heterosis has been positively correlated with distance between traits of the parents. Two pepper variety belongs different Capsicum species, non-pungent Santos Flame (Capsicum annuum L.) and Biquinho (Capsicum chinense Jacq.) which had very low capsaicinoid content were crossed to estimate mid parent heterosis, heterobeltiosis and standard heterosis. In this study extraordinary heterosis rates were calculated F1 progeny of two different Capsicum species close to pungency trait but definitely divergent genetically. The capsaicin content of Santos Flame, Biquinho and F1 progeny were 0 mg kg-1, 2.1 mg kg-1 and 217.4 mg kg-1, respectively. The highest mid parent heterosis was estimated from capsaicin content with 20605%. Similarly uncommonly heterobeltiosis and standard heterosis rate was estimated for capsaicin content with 10252% and 237%, respectively. Correlatively extreme heterosis rates were calculated for SHU pungency level, dihydrocapsaicin and total capsaicinoids content.
