| Abstract | ||
| Seeds of five new bread wheat entries ,Kea, Tr380, 2Ca, Tow”s” and Kvz in addition to the two local varieties, Saberbeg and Abou-Graib-3 were sown during the season 1997/1998 . Complete diallel cross program was applied for the seven parents . In the following season the performance of all the genotypes was evaluated through the study of the characters : number of days to 50% anthesis, plant height, number of spikes / plant, spike length, number of grains / spikes, biological yield / plant, grain yield / plant, harvest index, 1000-grain weight and protein percentage. Highly significant differences between genotypes were detected for the all characters. The entry, Tow”s” was superior for spike length, number of grains/spike, biological yield and 1000-grain weight, while the entry, Kea was exceeded on the others for number of spikes /plant and the reduction of plant height . Heterosis and heterobeltiosis for the two hybrids Abou-Graib-3 × Tr380 and Kvz × Tr380 were found for the number of spikes/plant, number of grains/spike, biological yield , grain yield/plant and 1000- grain weight. | ||
