Abstract

This study was conducted on greenhouse cucumber to generate inbred lines by self-pollination across six generations between 2016 and 2021ina private farm at 10th Ramadan association, Ismailia, Egypt. Ten F1 hybrids were produced by half-diallel crossings between the five inbred lines during 2021/2022 season. The genotypes and a check variety were evaluated during the two consecutive winter seasons 2022/2023 and 2023/2024.Main stem length, internode length, branches number, days until the first female flowering, node of the first female flower, number of female flowers per node, fruit weight, diameter, length and color, fruits number/plant, total yield/plant and weight loss during postharvest shelf-life traits were measured. The results showed highly significant differences among genotypes in all studied traits. Also, highly significant variances were observed for GCA and SCA for all traits during both seasons, which suggested that both additive and non-additive gene action were important in the expression of all characters. Furthermore, the cross P2 × P4 and P4 × P5 exhibited desirable values of SCA effects and heterosis for all studied traits. Mostly, the parentsP2, P4 and P5 could be used in breeding programs to produce parthenocarpicgynoecious hybrids of greenhouse cucumber.
