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.
