The Elite Cassava Genotypes with High Yield and Stability in Diverse Environmental Conditions of Ethiopia | Chapter 10 | Current Topics in Agricultural Sciences Vol. 2

 Cassava is primarily grown in Ethiopia's south area. It does, however, demonstrate expansion to the country's northern, eastern, and western regions. The evaluation of eleven cassava germplasms derived from prior exploratory work was carried out in this study under various agro-climatic conditions. 1038, 869, Umbure, M94/0117, 1554, 1630, 1708, M94/0125, 196/624, Kello (standard check), and Local farmers variety were among the cassava genotypes utilised in the study. These were planted in the 2015/2017 and 2017/2019 growth seasons. The experiment took place in Hawassa, Dilla, Areka, and Jima, among other places. The treatments were duplicated three times in a randomised full block design. Two computer statistical software tools, Gen Stat and SAS, were used to do the statistical study (1999). The analysis of variance was performed using SAS software. The stability of the genotypes across several locales was determined using the Gen Stat computer software. The results revealed that root yield differed significantly between cassava genotypes. Cassava genotypes 1708 and M94/125 were chosen as the best varieties based on genotypic stability index because to their good stability and yield performance in varied environmental circumstances. The correlation coefficient revealed a link between many agronomic traits. Total root yield of cassava was highly significant and positively correlated with stand count (r=0.90), storage root length (r=0.86), and storage root girth (r= -0.04). Total root yield to above ground biomass weight (r=-0.74), plant height (r=-0.77), and storage root girth (r=-0.04) were also highly significant and negatively correlated.
