qGW, a Stable and Major QTL for Increasing of Grain Weight in Rice (Oryza sativa L.)
In order to analyze the genetic components of agronomic traits among 116 F9 recombinant lines derived from crosses of Ahlamitarom × Sepidroud rice cultivars, an experiment was conducted as a randomized complete block design in research farm of Gonbad Kavous University of Agriculture with three replications in 2016 and 2017. Genetic linkage map provided with 80 SSR markers, 28 iPBS Markers (79 p...
متن کاملA large-effect QTL for grain weight in rice on chromosome 10
Grain yield of the rice can be enhanced through genetic manipulation of the yield components. Thousand grain weight is an important component which can be improved through conventional as well as molecular breeding approach. A major effect novel genomic region, TGW10, for high grain weight was identified through a bulked segregant analysis approach in Azucena × IR64 population. Markers associat...
متن کاملFine mapping of a grain-weight quantitative trait locus in the pericentromeric region of rice chromosome 3.
As the basis for fine mapping of a grain-weight QTL, gw3.1, a set of near isogenic lines (NILs), was developed from an Oryza sativa, cv. Jefferson x O. rufipogon (IRGC105491) population based on five generations of backcrossing and seven generations of selfing. Despite the use of an interspecific cross for mapping and the pericentromeric location of the QTL, we observed no suppression of recomb...
متن کاملQuantitative trait loci (QTL) analysis for rice grain width and fine mapping of an identified QTL allele gw-5 in a recombination hotspot region on chromosome 5.
Rice grain width and shape play a crucial role in determining grain quality and yield. The genetic basis of rice grain width was dissected into six additive quantitative trait loci (QTL) and 11 pairs of epistatic QTL using an F(7) recombinant inbred line (RIL) population derived from a single cross between Asominori (japonica) and IR24 (indica). QTL by environment interactions were evaluated in...
متن کاملQTL mapping of grain length in rice (Oryza sativa L.) using chromosome segment substitution lines.
Chromosome segment substitution (CSS) lines have the potential for use in QTL fine mapping and map-based cloning. The standard t-test used in the idealized case that each CSS line has a single segment from the donor parent is not suitable for non-idealized CSS lines carrying several substituted segments from the donor parent. In this study, we present a likelihood ratio test based on stepwise r...
