pyramiding genes related to grain quality and resistance through marker assisted selection (mas) is an important approach in rice breeding programs. marker-assisted selection can be used for monitoring the presence or absence of these genes in breeding populations and can be combined with conventional breeding approaches. this study is a part of cultivar development program in iran through inte...
Grain size traits are critical agronomic which directly determine grain yield, but the genetic bases of these still not well understood. In this study, a total 154 chromosome segment substitution lines (CSSLs) population derived from cross between japonica variety Koshihikari and an indica Nona Bokra was used to investigate length (GL), width (GW), length-width ratio (LWR), perimeter (GP), area...
Rice is a vital staple food crop worldwide, providing nutrition and sustenance to significant portion of the global population. The genetic diversity cultivated rice species has been significantly reduced during domestication, resulting in loss favorable alleles. To overcome this limitation, wild have used introgression breeding programs introduce beneficial In study, we performed syntenic phyl...
Reduced temperatures during germination adversely affect rice (Oryza sativa L.) production. Little is known, however, of the genes or genetic loci involved. Here, QTLs were investigated in a recombinant inbred line (RIL) resulting from 02428 (japonica)-YZX (indica) cross. The phenotypes cultivars differ significantly when exposed to low germination. Mapping with high-density bin map identified ...
Reproductive barriers perform a vital role during speciation. Hybrid weakness, the poorer development of hybrids compared with their parents, hinders gene exchange between different species at the postzygotic stage. Here we show that two incompatible dominant loci (Hwi1 and Hwi2) involving three genes are likely to determine the high temperature-dependent expression of hybrid weakness in inters...
The experiment was conducted to investigate the parental diversity along rice genome and understand screen out SSR markers-indicated polymorphism between two indica (Oryza sativa L.) cultivars. Namely K343, most well-liked variety in hill zone of Jammu Region, RML22, a line created at IRRI, Philippines. study is select polymorphic markers (Simple Sequence Repeat- SSR) associated with ecologies ...
