Association of Agronomic Traits with SNP Markers in Durum Wheat (Triticum turgidum L. durum (Desf.))
Association mapping is a powerful approach to detect associations between traits of interest and genetic markers based on linkage disequilibrium (LD) in molecular plant breeding. In this study, 150 accessions of worldwide originated durum wheat germplasm (Triticum turgidum spp. durum) were genotyped using 1,366 SNP markers. The extent of LD on each chromosome was evaluated. Association of singl...
متن کاملSNP-based association analysis for seedling traits in durum wheat (Triticum turgidum L. durum (Desf.))
In the present study, 150 accessions of worldwide originated durum wheat germplasm (Triticum turgidum spp. durum) were observed for major seedling traits and their growth. The accessions were evaluated for major seedling traits under controlled conditions of hydroponics at the 13th, 20th, 27th and 34th day-after germination. Biomass traits were measured at the 34th day-after germination. Correl...
متن کاملThe genetic control of the alpha-amylase isozymes of the durum wheat (Triticum durum Desf.).
The hybridological analysis was provided on several durum wheat genotypes with utilizing three F2 populations developed from the crossing between parental forms that differed in the invariable malt-zone triplet on electrophoretic spectrum of alpha-amylase. Three components of this zone are controlled by three genes with an independent way of inheritance: one of them is located on the 6B or 5B c...
متن کاملEffEctivE sElEction critEria for assEssing drought strEss tolErancE in durum whEat (TriTicum durum dEsf.)
Drought is a wide-spread problem seriously influencing durum wheat (Triticum durum Desf.) production and quality, but development of resistant cultivars is hampered by the lack of effective selection criteria. The objective of this study was to evaluate the ability of several selection indices to identify drought resistance cultivars under a variety of environmental conditions. Twenty four duru...
متن کاملGenetic analysis of agronomic and morphological traits of durum wheat [Triticum turgidum L. spp. durum (Desf.)] using generations mean analysis under non-stress and terminal drought stress conditions
Breeders often use generation means analysis to obtain information about inheritance, gene action, and to determine effective breeding methods to improve important agronomic traits, especially under drought stress conditions. To investigate the genetic parameters of agronomic and morphological traits in durum wheat, a field experiment was carried out using F1, F2, BC1 and BC2 generations obtain...
