Seven bread wheat (<em>Triticum<\/em> <em>aestivum<\/em> L.)\ngenotypes were used viz. Douma 64453, ACSAD 1252, ACSAD 1149, Douma 2, Douma 4,\nJawaher14 and Sham6. Half diallel mating method was followed to get 21 hybrids.\nThe hybrids and their parents were sown in the second season, using a\nrandomized complete block design with three replications to estimate general\ncombining ability, specific combining ability, dominance degree, and both mid and\nbetter parent heterosis for traits; number of days to heading, plant height, number of spikes per plant, number of grains per spike, biological yield per plant, thousand kernel weight, and grain yield per\nplant. The results indicated non-additive gene action in all trait inheritance,\nexcept number of spikes per plant, which was equally controlled by additive and non-additive\ngenes. Three parents had high general combiners for grain yield, i.e.\nDouma64453, ACSAD1252 and Jawaher14. Thus, the derived progenies of these\nparents in the breeding program will have high gene inheritance. Many hybrids\nwith positive specific combining ability were obtained from parents with\npositive general combining ability, which also have both mid and high parent\nheterosis, including (Sham6 x Douma64453), (ACSAD1252\nx Jawahar14), (Jawahar14 x Douma4) and (Sham6 x ACSAD1149). Thus theses hybrids\ncould be used for selection in segregating generations in order to reach high\nyielding wheat lines.&nbsp;&nbsp; <\/p>\n\n\n\n<p><strong>Key words<\/strong>: Bread wheat, Combining ability, Heterosis, Dominance degree.<\/p>\n\n\n\n<p>Full paper in Arabic: <a href=\"http:\/\/agri-research-journal.net\/sjar\/wp-content\/uploads\/2020\/06\/v7n3p17.pdf\">PDF<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mohamed Baker AlAbd AlWahed *(1) Ayman Alarfi (2) \u00a0and Jalal Abboud(3) (1).
