Inheritance of some technical characteristics of second-generation hybrid embryos F2 of crossbreeding in Triticum aestivum L.

Grains of F₂ generation from half diallel crosses between five varieties of bread wheat (<em>Triticum aestivum L.</em>) (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.<br /> 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.<br /> <strong> </strong>
