Genetic mapping of the qSBN7 locus, a QTL controlling secondary branch number per panicle in rice
Secondary branch number (SBN) is an important component affecting spikelet number per panicle (SPP) and yield in rice. During recurrent backcross breeding, four BC2F4 populations derived from the high-yield donor parent IR65598-112-2 and the recurrent parent Tainan 13 (a local japonica cultivar) showed discontinuous variations of SPP and SBN within populations. Genetic analysis of 92 BC2F4 indi...
متن کاملQuantitative trait loci mapping of panicle traits in rice
In this study 90 individuals of recombinant inbred lines (RILs) were developed by crossing subspecies of japonica rice cultivar, ‘Nagdong’ and an indica type cultivar, ‘Cheongcheong’. These individuals were used to identify the quantitative trait loci of panicle traits using SSR markers. A genetic linkage map was constructed using one hundred fifty four simple sequence repeat ...

متن کاملQuantitative trait loci mapping of the stigma exertion rate and spikelet number per panicle in rice (Oryza sativa L.).
The stigma exertion rate is a polygenic inherited trait that is important for increased seed yield in hybrid rice breeding. To identify quantitative trait loci (QTL) associated with high stigma exertion rate, we conducted QTL mapping using 134 recombinant inbred lines derived from XieqingzaoB and Zhonghui9308, which have high and low stigma exertion rates, respectively. A total of eight QTLs (q...
متن کاملDetection of QTLs on panicle and grain number in rice (Oryza sativaL): a review
Effective panicle number, grain number, and grain weight are the three components of rice yield, of which grain number shows the highest variation and makes the largest contribution to yield output.Rice panicle number per plant is a grain yield component that directly influences rice yield. The identification of the genes controlling panicle number will play a vital role in high-yield rice bree...
