摘要

Yield is a complex trait and is under the control of multiple genes in which the environment interfere on the phenotype. The estimation of genetic components, including non-allelic interactions acquire a great importance on the breeding of a crop. The objective of this study was to estimate the genetic parameters for yield, using generation means analysis (P1, P2, F1, F2, BC1 and BC2) derived from the cross of Pimenton Serrano and Aji Cayenne 958 (inbreed lines of Capsicum annuum). The analysis revealed that additive, dominance and the non-allelic interactions components were significantly for the phenotypic expression, indicating the need for a four-parameters model.Additive by additive [i] effects revealed significance for fruit weight. Recessive or double recessive epistasis, was found. Finally, a breeding program based on recurrent selection to increase the average yield in a pepper (Capsicum annuum) population can be used, due to the epistatic interaction can be effectively exploited through the hybridization among promissory lines.
