Importance 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 کاملConstruction and analysis of 2 reciprocal Arabidopsis introgression line populations.
Two new large reciprocal sets of introgression lines (ILs) were created between the Arabidopsis accessions Col-0 and C24. In both sets (78 ILs with Col-0 background and 62 ILs with C24 background), the donor segments cover almost the entire genome with an average substitution size of 18.3 cM. In addition to the basic sets of ILs, further subILs were developed for 2 genomic regions allowing bett...
متن کاملMapping QTL for Agronomic Traits on Wheat Chromosome 3A and a Comparison of Recombinant Inbred Chromosome Line Populations
Variation for wheat (Triticum aestivum L.) grain yield and agronomic traits was used to map quantitative trait loci (QTL) in a ‘Cheyenne’ (CNN) × [CNN (‘Wichita’ 3A)] recombinant inbred chromosome line (RICL) population consisting of 223 CNN(RICLs3A) and 7 check cultivars that were evaluated in six environments in Nebraska during 2005–2007. A chromosome 3A linkage map spanning 106 cM was constr...
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 کاملQuantitative trait loci in Two Soybean Recombinant Inbred Line Populations Segregating for Yield and Disease Resistance.
Molecular makers linked to quantitative trait loci (QTL) can assist soybean [Glycine max (L.) Merr.] breeders to combine traits of low heritability, such as yield, with disease resistance. The objective of this study was to identify markers linked to yield QTL in two recombinant inbred line (RIL) populations ['Essex' x 'Forrest' (ExF; n = 100) and 'Flyer' x 'Hartwig' (FxH; n = 94)] that also se...
