During the past 20 years of close collaboration with CIAT in the cassava breeding program in the Philippines, much has been achieved, not only in terms of human capacity building but also in the acquisition of improved cassava germplasm. These materials were used in a multy-year selection scheme,...

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...

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...

Dry yield and yield components from 6 multilocational trials of cassava genotypes conducted for 3 years in Nigeria were used to study the nature and magnitude of genotype x environment (G x E) interaction and to determine the optimum resource allocation for cassava yield trials. The effects of en...

Se comparó la productividad de plantaciones de Eucalyptus globulus en 436 parcelas establecidas en la Región del Maule. La comparación se llevó a cabo mediante un análisis de varianza del incremento medio en volumen por hectárea (IMA del volumen). Se consideró como fuente de variación la serie de...
