    Interdependence of seed yield components of pumpkin (Cucurbita pepo L.) genotypes
    (University of Banja Luka Faculty of Agriculture, 2022-05-26) Tomić, Dalibor; Marjanović, Miloš; Radovanovic, M.; Djurović, V.; Lazarević, Đorđe; Stevović, Vladeta; Pavlovic, N.
    The aim of this study was to analyze the interdependence of seed yield components of the pumpkin (Cucurbita pepo L.) genotypes, which are grown in Western and Central Serbia. The experiment was performed in the period 2021-2022. In the initial phase, the fruits of genotypes of pumpkin grown in the villages from Priboj in the south to Šabac in the north, Smederevska Palanka and Krusevac in the east were collected. A total of 81 pumpkin fruits of 27 different genotypes were gathered. The following yield components were analyzed on selected fruits: fruit weight, number of seeds per fruit, dry seed weight per fruit, thousand seed weight, kernel weight per fruit and kernel percentage. Fruit weight was significantly positively correlated with number of seeds per fruit, dry seed weight per fruit, kernel weight per fruit and thousand seed weight, and significantly negatively correlated with kernel percentage (r = -0.44). Fruit weight was not significantly correlated with number of seeds per fruit, while number of seeds per fruit was significantly positively correlated with seeds weight per fruit and kernel weight per fruit. Seeds weight per fruit was in a significant positive correlation with kernel weight per fruit and thousand seed weight. Kernel percentage was significantly positively correlated with the number of seeds per fruit, seeds weight per fruit, kernel weight per fruit and the thousand seed weight. The analyzed genotypes represent an important source of diversity that could be used in plant breeding studies in the future.
