Abstract

In order to investigate path analysis of grain yield and yield components, an experiment was carried out with 20 genotypes of wheat in a randomized complete block design with four replications in two places in North Khorasan Province, dry land Research Station of Shirvan and Sisab, Iran. In 2015-2016. During the growth stages and after harvesting, traits like plant height, number of days to heading, numbers of spikes per square meter, number of grains per spike, number of days to maturity, seed weight and seed yield were recorded. according to the analysis of variance, between genotypes in terms of number of days to heading, days to maturity, numbers of spikes per square meter, number of grains per spike and grain yield, differences were significant. According to the comparison of the averages, genotypes 17 and 12 with 2522 and 2364 kg. ha-1 had the highest grain yield respectively and genotype 20 with 1190 kg. ha-1grain yield was the lowest. Based on the path analysis results, the number of spike per square meter (69. 8%), the number of grains per spike (64. 9 %) and grain weight (38. 9 %) had the highest direct effect on grain yield. The Correlation coefficients showed that seed weight and number of grains per spike and number of spikes per square meter had a significant negative correlation and the number of grains per spike and number of spikes per square meter were significant positive correlation with yield.
