ANÁLISE DIALÉLICA DO POTENCIAL ORNAMENTAL EM PIMENTEIRAS

Abstract

Knowledge of the genetic control of traits is very important for efficient breeding programs. Based on the information on combining ability and gene action, the selected lines can be combined to exploit the hybrid vigor by the accumulation of non-additive or cultivars to evolve by the accumulation of additive genetic effects genetic effects. The diallel cross gives a good idea of general and specific combining ability of parents and hybrids The objective of this study was to determine , through a complete diallel , the effects of general combining ability , specific combining ability and reciprocal effects of ornamental pepper . Manual crosses between the parents, and later morphoagronomic of 49 descriptors suggested by IPGRI (1995) were performed. The data were previously submitted to analysis of variance with 1 % probability by F test at 1 % probability cluster medium by the method of Scott - Knott, a 5 % probability and analysis by the method of Griffing diallel. Effects of non-additive gene nature dominance and / or epistasis were predominant than additive for all traits. Parents indicated according to the figures are 349 and 348 hybrid 131 x 348, 132 x 348, 131 x 132 and 449 x 358 reciprocal, 449 x 348 and 348 x 131. According to the qualitative data is indicated 132 x 349 and 132 x 358.
