Relationships and Path Analysis among Traits in Different Grain Corn (Zea mays L.) Varieties

In the study conducted in the Altıeylül district of Balıkesir province, ten different grain hybrid corn varieties were grown with a row spacing of seventy cm and a plant spacing of fifteen cm in the 2022 corn growing season. Seven different characteristics of the varieties used in the study were examined: plant height, cob length, cob weight, cob diameter, cob grain number, cob grain weight and thousand grain weight. Path analysis and correlation analysis were used to examine the relationships between the examined traits and to determine the direct and indirect effects of these traits on grain weight in the cob. Correlation analysis showed that there were positive significant relationships between cob grain weight and cob length (0.775**), cob weight (0.941**), cob diameter (0.587**) and cob grain number (0.809**) traits. According to path analysis, cob weight, thousand grain weight and cob number had the greatest direct effect on cob grain weight trait. It was observed that cob length trait had small but positive effects on cob grain weight trait.
