Effect of amounts and time of methanol application on yield and yield components of spring safflower at Farahan

In order to study of some agronomic and phenological attributes, an experiment was conducted in 2010 at the farm of Moghan Agricultural Faculty, univ. of Mohaghegh Ardabili with use 29 spring bread wheat genotypes were planted in a Randomized Complete Block Design with three replications. The analysis of variance showed that among genotypes for grain yield, biological yield, harvest index, flag leaf area, flag leaf cholorophy scale and tillering time had significant difference in level %1 probability but, for flowering time and ripening time had not significant difference. The grain yield showed a significant positive correlation with biological yield, flag leaf area, flag leaf cholorophy scale and harvest index but, showed a negative correlation and significantly with tillering time. The flowering time have positive linkage and significantly with tillering time and showed negative correlation and significantly with havest index. According to the results, Shiroudi, Nick-Nejad & Alborz, cultivars many of agronomic & phenological traits, desirable and than the other genotypes excelled and produced acceptable grain yield. Therefore, can be expressed production in different whead cultivars influenced by its genotypes.
