Abstract

This experiment was conducted on research station farm of Mehregan in kermanshah province using RCBD design with 3 replications and 3 treatments including (irrigation by 7 days interval) versus (irrigation by 10 and 14 days intervals) on CORN single cross (704) in 2006. DROUGHT STRESS was exposed from flowering stage.The results showed that there were direct significant CORRELATIONs between the number of grain pre ear with grain yield pre plot at 1% and ear length, stem diameter and internode with grain yield pre plot at 5% levels in normal condition. There were also direct significant CORRELATIONs between the number of grain pre ear and ear length with grain yield pre plot at 1% and internode with grain yield pre plot at 5% levels in ten days irrigation interval. There were direct significant CORRELATIONs between internode, plant height, stem diameter and the number of grain pre ear with grain yield pre plot at 1% level in 14 days irrigation interval. Stepwise REGRESSION results showed two traits (number of grain pre ear and plant height) in 7 days irrigation interval and one trait (ear length) in 10 days irrigation interval and so the number of grain pre ear, one thousand grain weight, stem diameter in 14 days irrigation interval were inserted to REGRESSION model. In PATH ANALYSIS on the most important traits on grain yield pre plot, the number of grain pre ear, one thousand grain weight in normal condition and ear length, internode in ten days irrigation interval and the number of grain pre ear, one thousand grain weight in 14 days irrigation interval had the most direct effects on dependent variable. It can be concluded in the normal condition the vegetative traits such as stem thickness, internode and some of yield components such as the number of grain pre ear and length ear and so in the stress condition length ear, number and weight of grain are effective on grain yield generally.
