INHERITANCE OF SOME QUANTITATIVE CHARACTERS.IN SOME BREAD WHEAT (Triticum aesuivum L.) CROSSES

Abstract

• One of the most important choices breeders make is the selection of parental materials. The probability of developing new high-yielding lines with other desirable characters is enhanced by • crossing elite high-yielding parents. The major goals of this study are; (i) evaluation of parental genotypes for their yielding ability and leaf rust reaction under Nubaria conditions. (ii) Studying the heterosis, general and specific combining ability, heritability and correlation for yield and yield components. (iii) Detection of genetic polymorphism among parental genotypes. (vi) Assessment the usefulness of microsatellite markers as predictors of the amount of specific combining ability and heterosis. (v) Tagging and mapping of the important leaf rust resistance gene (Lr26) with SSR markers using F2 population.
