Abstract
The present experiment was conducted in 2015/16 season at Sakha Agricultural Research station, Kafr Elsheikh and Nubaria Research Station, Egypt. Four parents (Gemmeiza 9, Sids 12, Sids 1 and Cham 4) and three crosses (Gemmeiza 9 × Sids 12, Gemmeiza 9 × Cham 4 and Sids 1 × Cham 4) were used. Sixty families and 300 plants from each cross were evaluated with their parents at Sakha and Nubaria sites, respectively. The two parents of each of the three crosses were different significantly in most cases for plant height and grain yield and yield components at the two sites. There was sufficient genetic variance among the families at Sakha and among the plants at Nubaria in the studied crosses to estimate the genetic parameters. Gemmeiza 9 and Sids 1 were the highest parents for grain yield at the two sites. The overall F3 means surpassed the parents mean for most studied traits and the ranges of the F3 families outed the corresponding parents for most characters at the two sites. The genetic variances among the F3 families exceeded corresponding environmental variances for most characters at Sakha site. The environmental variances were higher than the corresponding genetic variances among plants within families and selection among individual plants within families could be effective for most characters at Sakha site. Relatively medium to high heritability and expected genetic advance estimates for most characters were recorded at the two sites. Based on selection for plants with grain yield higher than the highest parent, medium height, resistant to the three rusts, seventeen plants from 2700 plants and twenty-six plants from 900 plants were selected at Sakha and Nubaria sites, respectively and will be advanced in the F4.
