چکیده
To estimate genetic progress and the variation in agronomic characteristics and phenology in 15 bread wheat (Triticum aestivum L.) cultivars released in Iran between 1952 and 2009, a field experiment was conducted at the Seed and Plant Improvement Institute’s Research Field Station in Karaj, Iran, in the 2009-2010 and 2010-2011 growing seasons. Temporal variation trends of the measured traits revealed that grain yield and related traits have increased in more recently released cultivars, though thousand-grain weight has changed only slightly compared with older cultivars released during 1952-2009. Number of days to heading and to anthesis did not change in modern cultivars, but grain-filling period and days to physiological maturity did increase. Grain number spike-1 and rate of grain growth increased but plant height decreased in more recently released cultivars.
