In red pepper cultivation for spice production, harvesting the fruits is time consuming and high cost requiring process. Also all the cultivated pepper (Capsicum spp.) fruits for processing have to be separated from the pedicel after or before drying. The pedicel is tightly attached with the calyx to the fruit pod in most pepper cultivar. For this reason fruit detachment force (FDF) is an important trait to improve pepper cultivars suitable for mechanical harvesting. Gene action for FDF was calculated using inter-specific crosses between four C. annuum L. (3.860 to 7.340 N FDF) genotypes and C. chacoense Hunz. (0.199 N FDF), C. annuum variety 'Totolapa’ (0.173 N FDF). FDF values obtained from parents and F1 generation indicated that gene effects for this trait were mostly displayed dominance and additive. No differences were calculated with respect to heterosis both Capsicum species related FDF. Parents could generate hybrids with high degree of negative heterosis varying between 86.56% and 94.50% related with FDF. Except K7 x CC hybrid easily detached from the fruit with 0.153 N, all the hybrids have fruit detachment force over ʻTotolapaʼ.
