Capsicum baccatum is one of the main chili peppers cultivated in South America. However, most studies on genetics andbreeding have focused on C. annuum , and not C. baccatum . To gain more insights into C. baccatum genetics and breeding,this work estimated the combinatorial abilities of dedo-de-moça-type chili peppers ( C. baccatum var. pendulum ) in relationto morphoagronomic and biochemical traits, determined the genetic action involved in the expression of these traits, andidentifi ed the superior hybrid combinations. Crosses among the fi ve genotypes in a full diallel mating design resulted in 20F 1 hybrids. Morphoagronomic, phytochemical, and antioxidant data were obtained, and Griffi ng’s diallel model was usedto estimate the general and specifi c combining ability (GCA and SCA, respectively) as well as the reciprocal eff ect (RE). High diversity was observed for all traits among the parents and hybrids. Signifi cant eff ects of GCA, SCA, and RE werealso detected for the majority of traits, indicating that additive, non-additive, and cytoplasmic eff ects are involved in thegenetic control of these traits. The non-additive eff ects were predominant for most traits, and the ‘BRS Mari’ × ‘Mexicali’and ‘BRS Mari’ × ‘Hortivale’ hybrids were the most promising in terms of their yield per plant and their biochemical traits.
