Association mapping of drought tolerance and agronomic traits in rice (Oryza sativa L.) landraces

Abstract: Background Asian cultivars were predominantly represented in global rice panel selected for sequencing and to identify novel alleles for drought tolerance. Diverse genetic resources adapted to Indian subcontinent were not represented much in spite harboring useful alleles that could improve agronomic traits, stress resilience and productivity. These rice accessions are valuable genetic resource in developing rice varieties suited to different rice ecosystem that experiences varying drought stre… Show more

“…Other examples for terrestrial plants with high growth rates are annuals and biennials that also complete their life cycle in a relatively short period of time and grow where they can maintain access to water. These species may employ evasive approaches to keep internal water content high, e.g., by performing osmotic adjustment to maintain metabolic activity [48] and increasing their investment in water-mining root structures [49] (Table 1). These terrestrial plants do not put the brakes on growth until water becomes scarce, and then switch to seed production-reminiscent of the production of vegetative storage forms (turions) in Lemnaceae.…”

“…The outbreeding mating system and its ploidy level made conventional breeding challenging tasks in improving various agronomic traits in alfalfa ( Zhou et al, 2011 ) was reviewed recently by Stacy et al (2018) . Crop wild relatives are viewed as novel genetic resources and identified key traits to improve stress resilience in other major legume species ( Manavalan et al, 2015 ; Prince et al, 2015b , 2020 ; Beena et al, 2021 ). In this study, different alfalfa genotypes adapted to a mild desert climate (PI478573) and a cold region with a prolonged winter (PI502521) along with cultivar Bulldog805 were evaluated to identify beneficial leaf and root traits in alfalfa to increase productivity under water limitation.…”

“…is the most economically important crop, and a staple food for more than half of the global population [ 1 ]. Rice yield is frequently limited by several abiotic factors such as cold, flood, and drought caused by climate change [ 2 ]. Climate related diverse abiotic stresses are the principal sources of risk and uncertainties in agriculture and caused wide fluctuations in agricultural output [ 3 ].…”
