Mapping QTLs for salt tolerance in rice

Identifying markers associated with yield traits in Nagina22 rice mutants grown in low phosphorus field or in alternate wet/dry conditions

“…Extensive work has been carried out to map QTLs for P uptake and PUE and relevant QTLs have been identified in rice (Wissuwa et al, 1998;Wissuwa et al, 2002;Shimizu et al, 2004;Lang and Buu, 2006;Zhang et al, 2009, Gamuyao et al, 2012Wiel et al, 2016). Phosphorus uptake 1 (Pup1) and phosphorus starvation tolerance 1 (PsTOL1) QTLs lead to efficient P uptake and larger root system under P deficient conditions to take up more phosphorus in Kasalath, an Indian aus variety (Wissuwa et al, 2002;Gamuyao et al, 2012).…”

Identifying QTLs Associated and Marker-Assisted Selection for Salinity Tolerance at the Seedling, Vegetative and Reproductive Stages in Rice (Oryza Sativa L.)

“…Lang et al, [11] reported that salt tolerant genes tagging based on SSR markers with advanced backcross populations (BC2F2) of IR64/ChengHui 448, IR64/OM1706 and IR64/ FR13A derived alleles nearly located at on chromosome 1 while in the population of IR68552-55-3-2/OM1706, the alleles are linked with RM223 on chromosome 8. The major gene for salinity tolerance (Saltol) was mapped on chromosome 1 and chromosome 8 [12,11]. RM223 linked to salt tolerance gene at the distance of 6.3 cM on chromosome 8 at vegetative stage under EC = 10 dS.m -1 from F3 population of IR28/Doc Phung [12].…”

Sustainable Rice Yield in Water-Short Drought-Prone Environments: Conventional and Molecular Approaches

“…Nguyen et al (2004) fine-mapped a QTL (oa3.1) for osmotic adjustment under drought and identified the candidate genes. A major-effect QTL for drought recovery score (DRS) was fine-mapped on chromosome 9 (Lang & Buu, 2008). Efforts were also made at IRRI to fine-map four large-effect grain-yield QTLs under drought such as qDTY 2.1 , qDTY 2.2 , qDTY 9.1 , and qDTY 12.1 in backcross-derived advanced populations (Bernier et al, 2007; www.intechopen.com Venuprasad et al, 2009, Dixit et al, 2011.…”
