Research on Heat Stress of Rice in China: Progress and Prospect
There have been six times of severe heat damages happened to the mid-season rice in Yangtze River Valley (YRV), China during the past 50 years, with the latest one occurred in 2003. It was estimated that the involved acreage of rice in 2003 was about 3 million ha, with a loss of about 5.18 million rice grain yields. The serious heat stress situation in YRV might be closely correlated with the c...
متن کاملIs early morning flowering an effective trait to minimize heat stress damage during flowering in rice?
Higher spikelet sterility due to heat stress exposure during flowering in rice is becoming a major threat for sustaining productivity in tropical and sub-tropical regions. Therefore, exploiting and incorporating early morning flowering (EMF) trait into ongoing breeding pipelines could be an effective strategy to minimize the damage. In this study, we have focused on quantifying the time of day ...
متن کاملqEMF3, a novel QTL for the early-morning flowering trait from wild rice, Oryza officinalis, to mitigate heat stress damage at flowering in rice, O. sativa
A decline in rice (Oryza sativa L.) production caused by heat stress is one of the biggest concerns resulting from future climate change. Rice spikelets are most susceptible to heat stress at flowering. The early-morning flowering (EMF) trait mitigates heat-induced spikelet sterility at the flowering stage by escaping heat stress during the daytime. We attempted to develop near-isogenic lines (...
متن کاملGenetic Structure of Salinity Tolerance in Rice at Seedling Stage
The Oryza sativa L. F8 population derived from a cross between salt tolerance cv. Ahlemi Tarom and salt sensitive cv. Neda was used in the study. Germinated seeds floated on water for 3 d, and after were transferred to float on Yoshida's nutrient solution for 11 d. two weeks after sowing, the seedling was transferred to nutrient solution containing 51.19 mM NaCl (electrical conductivity 6 dSm-1...
