Abstract

In order to investigate the change in morphological and Physiological aspects of different WHEAT CULTIVARS and effect of them on increasing yield potential, an experiment was conducted in 1999 at the farm of agriculture faculty, Ferdowsi University of Mashhad. In this experiment, twelve WHEAT CULTIVARS, which were released during the years of 1951-1995, were experimented in a Randomized Complete Block Design with three replications. The results indicated that Alamo cultivar with yield of 4259 kg/ha and the Omid cultivar with 2963 kg/ha had the highest and lowest yields, respectively and other cultivars had no statistical significant difference in this case. All cultivar differenced in total biomass and in this case Navid cultivar had the highest biomass (16630 kg/ha) and Ghods cultivar had the lowest (10300 kg/ha) while between the cultivars, the highest HARVEST INDEX belong to Ghods and the lowest belong to Omid cultivar. Also in three cultivars, between H.I. and GRAIN YIELD existed high positive correlation (R=0.65) but, GRAIN YIELD did not show any correlation with total biomass. The amount of extinction coefficient (k) was higher in new cultivars compared to old cultivars. So that Azadi and Bezostaya cultivars had the highest (K=0.6) and lowest (K=0.26) respectively. The cultivars of third group had less tillering compared to other groups that indicate densitibility at new cultivars to old cultivars. Leaf Area index and Relative Growth Rate were higher at first group compared to other groups. Chlorophyll amount was difference until an thesis stage but did not exist any difference in an thesis stage. That was negative correlation between wheat heights and releasing year at all groups. Old cultivars had higher stem length and less number of grain in spike than new cultivars, but had no significant difference in grain thousand weights. Analysis between different traits indicated relatively positive correlation between flag leaf area and GRAIN YIELD (R=0.99), high negative correlation between plant height and GRAIN YIELD (R=-0.51) and, high negative correlation (R=-0.99) between number of floret in spike and GRAIN YIELD.
