| Abstract | ||
| Selection is the first step in a successful pepper breeding program of parents and genetic diversity is one of the criteria for selection of parents in hybrid production. Six successive seasons (2019 early spring and autumn and the winter season of 2020, 2021, 2022 and 2023) field experiments on pepper were carried out at Experimental Farm, Fac. Agric., Zagazig Univ., Egypt to improve superior dolma pepper genotypes that are highly adaptive to the local environment, high-yielding, and high-quality. Results indicated that there were three genotypes showed high coefficient of variation (CV%) for yield/ plant. Fourteen genotypes recorded low CV% (Less than 10%) and showed values nearly similar that of the check hybrid (Control). The mean performance of total yield per plant showing that the new selected genotype (BS-5-2) widely varied in this trait. Estimated genetic parameters of the new selected genotypes showed a noticeable amount of environmental effect for total yield per plant. The heritability in broad sense (h2bs) represents the proportion of genotypic variations that is passed from parent to progeny, it was 0.91, 0.92 and 0.95% for average fruit weight, total yield per plant and fruit diameter, respectively. The genotypes (BS-5-2, M-19-4, TOP-4-2 and 90-17-3) were considered the best genotype for yield per plant and could be used in breeding program to develop new local F1 hybrids of dolma pepper. | ||
