Genotype [1] Environment Interaction and Stability Analysis of Selected Cassava Cultivars in South Africa

This is a scientific research report published by the National Agricultural Marketing Council (NAMC) on the performance of selected cassava genotypes across different environments in South Africa. It analyzes genotype × environment interaction (GEI), fresh root yield (FRY), and dry matter content (DMC), identifying stable and high-yielding cassava varieties suitable for farming and industrial use. The study recommends specific genotypes and testing sites for future breeding and evaluation programs.
