Development And Characterization Of Rice Genotypes For Water Use Efficiency And Drought Resistance, Anuj Kumar
Development And Characterization Of Rice Genotypes For Water Use Efficiency And Drought Resistance, Anuj Kumar
Graduate Theses and Dissertations
Rice, the second largest staple food crop, uses 30% of global fresh water to complete its life cycle worldwide. Water deficits worldwide have become a serious problem affecting rice growth and ultimately grain yield. To solve the water problem globally, improvement of water use efficiency (WUE) and other drought resistance (DR) traits in rice genotypes would be a useful strategy using advanced genomics tools. In this study, our objectives were to 1) analyze phenotypes of the USDA rice mini-core collection (URMC) for WUE and DR related traits, 2) correlate drought response phenes for physiological traits and grain yield in the …

Disaggregating The Effect Of Drought And Heat Stress During Flowering On Spikelet Fertility In Rice, Lisa Straussberger
Graduate Theses and Dissertations
Due to rice’s wide geographic distribution, extending from 50°N to 35°S, rice is
forecasted to be the most vulnerable crop to warming global climates. Previous studies have
predicted lower rice yields and increasing rice yield variability due to higher frequencies of heat
stress events, and a higher variability in precipitation patterns due to global warming. As such,
understanding the effects of drought and heat stress intensity and frequency on rice yields is of
upmost importance to feeding the growing global population.
Given that drought and high-temperature stress often occur together, it is essential to
disaggregate the two individual stressors and …
