| Abstract | ||
| Grains of F2 generation from half diallel crosses between five varieties of bread wheat (Triticum aestivum L.) (Intesar, Rabbea'a, Bbu-Greeb-3- A dnanyi and Al-Eaz) were used to estimate general combining ability for parental varieties, specific combining ability for their crosses. Inbreeding depression in F2 generation and Broad sense heritability for the following traits : total flour content, bran content, extracted flour, wet and dry gluten content, Fermentation time. The results indicated that there were additive and non-additive gene effects for all he studied traits. The non-additive gene effects were more important than the additive for determining these characters. Some of hybrids showed significant positive values and others showed significant negative values inbreeding depression in F2 for the studied traits. Broad sense heritability values were high for the all characters. | ||
