Seed Yield and Characteristics in a Half-Diallel Pumpkin Population

Abstract

In addition to fresh and roasted pumpkin seeds used in human nutrition, they are used as an additive to bread, salami, sausage, mayonnaise and many food products because of their high protein content. The most common problem encountered in the cultivation of confectionary pumpkin is the lack of varieties with good seed yield and quality in the market. In this study, it was aimed to reveal the promising hybrids with superior characteristics by determining the yield and seed characteristics of the 13 pumpkin inbred lines (Cucurita pepo) and 74 hybrid lines which are obtained by crossing between inbred lines and two local varieties (3-Hatun Tirnagi and 4-Cercevelik) as control. As a result of the study, the highest positive correlation was found between seed thickness and 1000 seed weight and between seed length and seed width. The crosses of 31x34, 23x28, 13x23, 38x40, 29x37, 30x31 and 23x29, especially 40x29, in the positive region of both components showed superior performance compared to their parents in all parameters. These hybrids have emerged as promising crosses to develop the F 1 hybrid confectionary pumpkin varieties.

“…Kayak et al (2020) reported that the G39 genotype, located in the positive region of both components, showed superior characteristics in terms of yield and fruit quality and could be a promising cultivar candidate in their melon study. Similarly, Seymen (2020) reported that the hybrid cultivar candidates 31x34, 23x28, 13x23, 38x40, 29x37, 30x31 and 23x29 and 40x29, located in the positive region of both components, are promising. In conclusion, with the study, some yield and quality characteristics of 85 hybrid melon cultivar candidates were revealed in Konya ecological conditions.…”

“…In the study, F1 melon cultivar candidates were tried to be defined with the loading plot graph drawn from the first four components because of PCA made from yield and fruit parameters obtained from 85 melon cultivar candidates (Figure 1). Similar methods have been applied in different studies to identify genotypes in a large genetic pool (Seymen et al, 2019;Kayak et al, 2020;Seymen, 2020). When the figure is examined, the positive region of PC1 was the region explained in terms of fruit rind color.…”
