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 کاملFlowering Time Genes Heading date 1 and Early heading date 1 Together Control Panicle Development in Rice
Although flowering time is often associated with plant size, little is known about how flowering time genes affect plant architecture. We grew four rice lines having different flowering time genotypes (hd1 ehd1, hd1 Ehd1, Hd1 ehd1 and Hd1 Ehd1) under distinct photoperiod conditions. By using genotype-treatment combinations that resulted in similar flowering times, we were able to compare the ef...
متن کاملGenetic dissection of QTLs and differentiation analysis of alleles for heading date genes in rice
Heading date is an important agronomic trait in rice (Oryza sativa L.); it determines the geographical and seasonal adaptability of the crop. Single segment substitution lines (SSSLs) have become the preferred experimental materials in mapping functional genetic variations as the particular chromosome segments from donor genotypes can be evaluated for their impact on the phenotype in a recurren...
متن کاملImportance of QTL Mapping for Heading Date in Rice
Heading date in rice is one of the most important indices in rice breeding being governed by multiple genes known as quantitative trait loci (QTLs). This character along with grain yield determines the commercial potential of any rice cultivar. In the last three decades the development of DNA markers have led to the precise analysis of QTLs. Various mapping populations are being used to explore...
