Genetic analysis and validation of quantitative trait loci associated with reproductive-growth traits and grain yield under drought stress in a doubled haploid line population of rice (Oryza sativa L.)

Molecular Mapping and Breeding of Physiological Traits

“…Recently, in Adaysel/IR64-derived populations four major-effect QTLs, qDTY2.2, qDTY4.1, qDTY9.1, and qDTY10.1 have been identified [80]. In addition to this, 23 QTLs linked to plant phenology and production traits under stress using meta-analysis, have also been identified [81]. SNAC1 gene, under drought condition is induced in guard cells mainly which encodes a NAM, ATAF and CUC (NAC) transcription factor with transactivation activity [82][83][84].…”

Development of Drought Resistance in Rice

“…Yield losses ranging from 15 to 50% has been reported (Srividhya et al, 2011). Chronic dry spells even for a short period affects the crop and it becomes more severe when flowering period coincides with the drought period (Boonjung and Fukai, 1996;Saini and Westgate, 2000;Pantuwan et al, 2002;Lanceras et al, 2004;Venuprasad et al, 2008;Sellamuthu et al, 2011;He and Serraj, 2012;Yadaw et al, 2013;Ha et al, 2016).…”

Screening of some rice varieties and landraces cultivated in Nigeria for drought tolerance based on phenotypic traits and their association with SSR polymorphism

“…It is generally valued for its high nutritional benefits apart from being rich in calories, it is high in fibre, vitamins and minerals and low in cholesterol and sodium, suggesting it is a healthy source of energy. Asia is the largest producer and consumer of rice (Khush, 2005;Sellamuthu et al, 2011). In 2009, Nigeria was ranked 12th in the world's list of rice-consuming countries, while it is ranked 17th globally, third in Africa and first in West Africa, as producers of rice (FAO, 2011).…”
