Correlation and Path Coefficient Analysis in Some Bread Wheat (Triticum aestivum L.) Genotypes

23250

wheat has an important place in human nutrition in the world and our country because of including the basic food groups vitamins, minerals, carbohydrates, fiber and other nutrients. It is also one of the main species of cereals in solving the world hunger problem. The successful of the breeding programs depends on the separating and examining the direct and indirect interaction occurs between yield, yield components and the quality in detail. This study was aimed to determine the direct and indirect effects of some yield components on grain yield using total of 14 wheat genotypes consisted of 9 bread wheat lines, 4 registered varieties and 1 advanced line in two growing seasons. The experiments were conducted using a randomized complete block design with 3 replications pattern in 2013-2014 and 2014-2015 wheat growing seasons. According to the results, it was determined that the correlation between grain yield and 1000 grain weights was significant and negative and the correlations between grain yield and other traits were the insignificant. Path analysis results showed that, the number of spike per m2 and test weight in the first year and plant height and test weight in the second year had the highest direct effects on grain yield. 1000 grain weight had the negative of direct effect on grain yield in both two years. As a result, these traits with direct positive effect on grain yield should be considered as selection criteria and emphasized in future wheat breeding program.
