Path Coefficient and Correlation Analysis in Bread Wheat (Triticum aestivum L.) Varieties for Some Agronomical Traits

Abstract

In this study, the relationships among yield, yield components and quality traits of some bread wheat varieties registered in Turkey were investigated using correlation and path coefficient analysis. Eighteen commercial bread wheat varieties were used in a randomized complete block design experiment with four replications at ecological conditions of Bolu in 2016-17 and 2017-18 cropping seasons. Based on the two-years data, positive and significant relationship was found between grain yield and plant height (0.755 **), and a positive relationship was found among grain yield and heading date (0.118), spike length (0.141), spikelet number per spike (0.210), grain number per spike (0.223), 1000-grain weight (0.015) and gluten content (0.274). According to the path coefficient analysis, plant height (p = 0.8984, 76.73%), heading date (p = 0.3935, 21.53%), grain number per spike (p = 0.6048, 29.33%), test weight (p = 0.9446, 41.06%) and gluten content (p = 0.4310, 28.86%) had direct and positive effects, while spikelet number per spike (p = -0.8489, 38.04%) and protein ratio (p = -0.9257, 39.04%) had negative effects. It was concluded that, yield components and quality traits that were positively related with grain yield could be used as selection criteria in breeding programs in Bolu conditions.
