Recent progress in cassava varietal improvement and agronomy research in Malaysia
Tan, Swee Lian | Chan, S.K.
A total of four sets of seeds (totalling 5526 seeds) were received from CIAT during the period 1990-1993. One set (comprising 1100 hybrid seeds) originated from the Thai-CIAT program in Rayong. Evaluation and selection of seedling clones has progressed satisfactorily, and culminated in the release on August 9, 1992 of an early clone (CM3906-31) named MM 92. This cultivar is capable of yielding 30 t/ha of fresh roots on drained peat after six months, and up to 40 t/ha on mineral soils. Starch content, however, was low at 20 percent. Agronomic research included studies on the effect of spacing and fertilizer rates on the yield of Perintis (released in 1988) and MM 92 grown on peat. A long-term fertility trial on peat has now completed its ninth cropping cycle.
