Influence of epistasis and QTL x environment interaction on heading date of rice (Oryza sativa L.).
QTLs for heading date of rice (Oryza sativa L.) with additive, epistatic, and QTL x environment (QE) interaction effects were studied using a mixed-model-based composite interval mapping (MCIM) method and a double haploid (DH) population derived from IR64/Azucena in two crop seasons. Fourteen QTLs conferring heading date in rice, which were distributed on ten chromosomes except for chromosomes ...
متن کاملIdentification 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 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...
متن کاملAssociation mapping for yield and grain quality traits in rice (Oryza sativa L.)
Association analysis was applied to a panel of accessions of Embrapa Rice Core Collection (ERiCC) with 86 SSR and field data from two experiments. A clear subdivision between lowland and upland accessions was apparent, thereby indicating the presence of population structure. Thirty-two accessions with admixed ancestry were identified through structure analysis, these being discarded from associ...
متن کاملMapping quantitative trait loci (QTL) associated with cooking quality in rice (Oryza sativa L.)
A mapping population consisting of 236 F2:3 families derived from the cross between two rice varieties, Gharib as female parent (with good cooking quality) and Sepidroud as male parent (with poor cooking quality) was used to analyze the quantitative trait loci (QTLs) associated with amylose content (AC), gelatinisation temperature (GT) and gel consistency (GC). A total of 105 single sequence re...
