A genetic map was constructed with 126 polymorphic SSR and EST derived markers, which were distributed across rice genome. QTL analysis using inclusive composite interval mapping (ICIM) method identified a total of 24 major and minor effect QTLs. Among them, twelve major effect QTLs were identified for days to fifty percent flowering (<i>qDFF12-1</i>), total grain yield/plant (<i>qYLD3-1</i> and <i>qYLD6-1</i>), test (1,000) grain weight (<i>qTGW6-1</i> and <i>qTGW7-1</i>), panicle weight (<i>qPW9-1</i>), plant height (<i>qPH12-1</i>), flag leaf len3 BiotechMapping novel QTLs for yield related traits from a popular rice hybrid KRH-2 derived doubled haploid (DH) population.PMC8630253DST/INSPIRE Fellowship/2013/1146Chaitra KSundaram RMBalakrishnan DKale RRAleena DPranathi KDas MAUlaganathan KPrasad ASHBalachandran SMSinha PRekha GHajira SKDilip TKulkarni SRAnila MKousik MBVNPunniakoti EShaik MfalseMapping novel QTLs for yield related traits from a popular rice hybrid KRH-2 derived doubled haploid (DH) population.A doubled haploid (DH) population consisting of 125 DHLs derived from the popular rice hybrid, KRH-2 (IR58025A/KMR3R) was utilized for Quantitative Trait Loci (QTL) mapping to identify novel genomic regions associated with yield related traits.
