Hybrid rice means more riceSustaining food security and alleviating poverty in the developing countries of tropical Asia require higher rice yields achieved at lower costs. Hybrid rice technology - including well-organized technology-transfer programs and efficient seed production to supply affordable, high-quality seed-can contribute significantly toward attaining this goal. Hybrid rice technology Hybrid rice technology has proved to be a potent technology to increase yield 15–20% (1–1.5 t/ha) above that of the current high-yielding varieties. This technology has been used extensively since 1976 in China, where about 50% of the rice area is covered with rice hybrids producing 60% of the total rice production. Outside China, this technology has been developed during the past 25 years with the help of the International Rice Research Institute (IRRI), which has played a lead role in collaboration with several countries. Since 1998, the Asian Development Bank (ADB) has provided funds to expedite the development and dissemination of this technology in selected member countries. More... Elite CMS lines for the tropics
Better hybrids identified in Vietnam Vietnam, in its search for hybrids better than those on the market today, has identified new promising combinations. More... New publications Two new books that provide useful information for research and training in hybrid rice technology are now available. The first is “Hybrid Rice for Food Security, Poverty Alleviation, and Environmental Protection” (Eds. S.S. Virmani, C.X. Mao, and B. Hardy), Proceedings of the 4th International Symposium on Hybrid Rice held in Hanoi, Vietnam, 14-17 May, 2002. The second is “Two-Line Hybrid Rice Breeding Manual” by S.S. Virmani, Z.X. Sun, T.M. Mou, A. Jauhar Ali, and C.X. Mao, published in collaboration with the China National Rice Research Institute, which conducted a collaborative international training course on hybrid rice breeding in August 2000. The training course was funded by the IRRI-ADB project.

Since
1989, the International Rice Research Institute has been
sharing hybrid rice parental lines developed by its
hybrid rice breeding group. This group, headed by
principal scientist Dr. Sant Virmani, is responsible for
developing parental lines and experimantal rice hybrids
for the tropics.
