Summary

Rice is a major source of global food calories. Increasing population pressure, unpredictable rainfall patterns, shrinking fresh water resources, and increased frequency of severe drought spells in recent years are the reasons behind putting concerted efforts toward breeding drought-tolerant rice cultivars much needed by the rice farmers. Attempts to breed rice for stress environments have made limited progress so far, but success with recent research on identification of major QTL (quantitative trait loci) for grain yield under drought shows that genomics-assisted breeding could be a viable alternative to enhance grain yield under drought. Major QTL with consistent effects on grain yield under drought and different drought-related traits have been mapped on rice chromosome 1, 2, 3, 9, and 12 and search is on for the genes underlying these QTL. Direct selection for yield under drought has emerged as an important criterion for both conventional and molecular breeding approaches. Transgenic rice with overexpression of transcription factors such as DREB1 and SNAC1 has shown considerable promise, but its use in breeding is still impeded.
