%0 Journal Article %T Study of Genetic Architecture of Some Important Agronomic Traits in Durum Wheat (Triticum durum Desf.) %A Muhammad Kashif %A Javed Ahmad %A Muhammad Aslam Chowdhry %A Khalida Perveen %J Asian Journal of Plant Sciences %D 2003 %I %X Gene action and components of variance analysis were made in a 6X6 diallel cross in durum wheat (Triticum durum Desf.). Additive gene effects were more important for all the traits. Complete dominance for yield plant-1 and spike length and over dominance for tillers plant-1 was observed. While plant height, spikelets spike-1, grains spike-1 and 1000-grain weight exhibited partial dominance. Dominant alleles were more frequent in parents for all characters except plant height and 1000-grain weight. Durum wheat genotypes, Altar 84 and Bittern "s" showed relatively higher combining ability. %K wheat %K genetic architecture %U http://docsdrive.com/pdfs/ansinet/ajps/2003/708-712.pdf
