2022 Yam morphological characterization
Genetic resources center of the International Institute of Tropical Agriculture characterized significant numbers of Yam accessions 20/08/2022 to 22/1/2023. For each accession five different plants were characterized , in which the mode of qualitative traits were calculated to represent each accession while for quantitative traits the mean of the five plants were calculated to represent each accessions.The vegetative data were captured at two different stages :Young stage, when the plants were two months old after planting and Matured stage at four months after planting. Reason for capturing the data : is to identify the variation within the plants using the IPGRI yam descriptor.
