| Abstract | ||
| Four bread wheat cultivars, namely; Sakha 93, Misr1, Gemmeiza 9 and Sids 12 were gown in two different environments in Wheat Research Department, Sakha station (North Egypt) and Asouyt station (South Egypt) during two growing seasons; 2010/2011 and 2011/2012. Data were recorded for yield and its components (grain yield, no. of kernels/spikes, no. of spikes/m2 and kernels weight) as well as some morphological characters (days to heading, days to maturity, grain filling period, grain filling rate and plant height). The results appeared that Sids 12 and Misr1 were the highest cultivars in grain yield at Asouyt station (South Egypt), while Misr1 was the greatest in grain yield at Sakha station (North Egypt). Grain yield, plant height, no. of kernels/spikes, no. of spike/m2 and days to maturity were decreased at South Egypt than at Sakha station. Therefore, the current study concluded that it is possible to utilize wheat yield and its components as a good indicator to estimate the impact of heat on the wheat productivity, tolerant and characteristics. | ||
