Effects of the combining ability on mirador chili (Capsicum annuum L.) populations native to Veracruz, Mexico

Abstract

Objective: Evaluate the effects of general and specific combining ability in agronomic characters of native populations of mirador pepper and identify genotypes with potential for the genetic improvement of the crop.

Design/methodology/approach: The general and specific combining ability for agronomic and yield characteristics was calculated in five mirador pepper populations, using method 2, Griffing model I, which includes the parents and direct crosses.

Results: The P1, P4 and P3 genotypes presented the highest values, positive and with a significant difference for general combining ability, while for specific combining ability the highest value was observed for the P1xP5 and P4xP5 crosses.

Limitations on study/implications: It was not possible to establish diverse evaluation environments and genomic selection studies using molecular markers.

Findings/conclusions: Information was generated on the yield potential of five mirador pepper populations, of importance for a genetic improvement program and for the selection of the improvement method.
