The success or failure of any large-scale crop breeding program should be measured by achievement of the following step-by-step goals:
1) Establishment of a breeding program
2) Building of effective research capability
3) A large number of genotypes produced and evaluated
4) Selection of superior...

Socio-economic contribution of cassava varietal improvement to the small farmer communities in Asia
Before 1985, Gon, H34 and Xanh Vinh Phu were the most popular cassava varieties in Vietnam. From 1986 to 1993, HL20, HL23 and HL24 were selected from the local variety collection by Hung Loc Agricultural Research Center (HARC) and were grown extensively in South Vietnam with annual areas of about...

Cassava varietal dissemination in Vietnam
In Thailand cassava breeding is the responsibility of the Rayong Field Crops Research Center of the Department of Agriculture (DOA), and of Kasetsart University (KU). From 1975 to 1992, six cultivars have been released for industrial use, i.e. Rayong 1, Rayong 3, Rayong 60, Rayong 90, Sri Racha 1...
In recent years (1990-1995) the cassava area in Vietnam has remained stable, or has increased slightly in the south due to the new demand for cassava roots used for starch processing. Therefore, our cassava breeding program, in collaboration with CIAT, has put a high priority on developing new va...
If a wholesale yield improvement of major crops by new high yielding cultivars was the definition of "Green Revolution", it was also a tacit expectation that a success similar to that in rice or wheat would be repeated in cassava when a cassava varietal improvement program was established at CIAT...
Cassava is after maize an important subsidiary crop in Vietnam. The amount of production used for human consumption is now only about 10-20 percent, that for animal feed increased to about 30 percent, for industrial processing about 30-40 percent, while about 20 percent is used for other requirem...
Five cassava cultivars for industrial purposes, Rayong 3, Rayong 60, Sriracha 1, Rayong 90 and Kasetsart 50, were released during 1984-1992. New cultivars were simultaneously evaluated in research stations and farmers' fields in 53 locations during 1991 and 1992. Yields of each cultivar were regr...
