The Guangxi Subtropical Crops Research Institute (GSCRI) began their cassava varietal introduction and improvement program in 1981. Since 1985, GSCRI has introduced cassava hybrid seeds as well as promising clones by tissue culture from CIAT/Colombia, from the Thai CIAT program, as well as from o...
During the past 16 years the Chinese Academy of Tropical and Agricultural Sciences (CATAS) has made good progress in developing improved cassava varieties for China. Several improved varieties have been released in south China, of which cv. SC124, with high yield and good cold resistance, is alre...

Different aspects of cassava cultivation in Cuba are described, namely agroclimatic regions, climate, prevailing soils, area and production, production systems, clones, and uses. Although cassava is planted on marginal soils with little availability of irrigation, if any, yields have increased as...
Se describen diferentes aspectos del cultivo de la yuca en Cuba, a saber: regiones agroclimaticas, clima, suelos predominantes, area y produccion, sistemas de produccion, clones y usos. A pesar de que la yuca se siembra en suelos marginales con poca o ninguna disponibilidad de riego, los rendimie...
Cassava varietal improvement in China has historically been conducted by collecting and evaluating local varieties, by introducing and testing of cassava germplasm from abroad, followed by the establishment of a cassava cross-breeding program. Considerable progresses has been made in the followin...

High-yielding varieties, adapted to local conditions and satisfying local preferences, is one of the most important components of improved technologies. Since cassava is propagated vegetatively using farmers’ own planting material, the use of high-yielding varieties will give substantial economic...

The paper reviews cassava breeding and agronomy research carried out by MARDI over the 15-year period, 1984-1999. Evaluation of seedling clones derived from sexual seeds introduced from CIAT/Colombia and the Thai-CIAT program has culminated in the release of two varieties: Perintis (in 1988), whi...

A complementary methodology to select cassava clones in advanced stages of assessment is presented; this methodology should be carried out jointly by farmers and researchers and thus increase the possibility of adoption of the selected clones. An attempt was made to establish feedback between tra...
