Identification of major and minor genes associated with heading date in an indica × indica cross of rice (Oryza Sativa L.)
In this study, quantitative trait loci (QTLs) controlling rice heading date were detected in a F2:3 population derived from a cross between an indica rice variety, Tarom Mahalli, with early heading date, and an indica variety, Khazar, with late heading date. SSR linkage map was constructed using 74 polymorphic markers and 192 F2 individuals and covered a total of 1231.50 cM of rice genome. QTL ...
متن کاملQTL mapping of heading date and plant height in Barley cross “Azumamugi”דKanto Nakate Gold
To identify quantitative trait loci (QTLs) controlling heading date and plant height, ninety nine F13 recombinant inbred lines (RILs) derived from barley cultivars Azumamugi × Kanto Nakate Gold cross were evaluated. The field trails were conducted at randomized complete block design with two and three replications in 2004 and 2005, respectively. Significant differences and transgrassive segrega...
متن کاملAssociation of functional nucleotide polymorphisms at DTH2 with the northward expansion of rice cultivation in Asia.
Flowering time (i.e., heading date in crops) is an important ecological trait that determines growing seasons and regional adaptability of plants to specific natural environments. Rice (Oryza sativa L.) is a short-day plant that originated in the tropics. Increasing evidence suggests that the northward expansion of cultivated rice was accompanied by human selection of the heading date under non...
متن کاملGiving Rice the Time of Day: Molecular Identification of a Major Photoperiod Sensitivity Quantitative Trait Locus
Daylength controls flowering in many plant species. Early in the twentieth century, Garner and Allard (1920) first described the phenomenon of plants that flower only when daylength is longer or shorter than a particular threshold, named long-day and shortday plants, respectively. Rice is a shortday plant; flowering (termed “heading” in rice and other cereals) is promoted by short daylength. Ho...
