Popis:	This work aimed to estimate genetic parameters in a diallel on in vitro seed germination in ornamental chilli pepper, according to the Haymans method (1954). The experimental design used was a randomized design, with five replications. Each replicate consisted of ten seeds/petri dish containing 30 ml of Murashige and Skoog (1962) (MS) medium. Four parents and their F1 hybrids were evaluated. There were significant differences between genotypes at 5% of probability by F test. The results showed seed germination is determined by dominance effects. The D-H1 showed the overdominance relationship between the alleles. The estimates of genotypic determination coefficient in the broad sense was 0.75 and the heritability in the restrict sense was 0.21. These data corroborate the hypothesis of prevalence of dominance effects. The selection of genotypes in segregating generations, with the greatest percentage of seed germination is difficult to obtain, because the genotypic determination coefficient is high but the main gene effect is dominant.
