Among the major root and tuber crops, anchote is a potential crop produced in Western parts of Ethiopia. In addition to food source, it takes wide portion in socio-economic, cultural and medicinal value for the farming communities. To study the indigenous knowledge on utilization and conservation of anchote, ethno-botanical survey was conducted in 2012 for continuous three months (February, March and April) in Western part of Ethiopia. The landraces were also collected during survey. Forty nine anchote landraces were tested in 7x7 Simple Lattice Design at Wayu Tuqa District of East Wollega in 2012/013. The survey results showed that most of the respondents had sufficient experiences of growing Coccinia abyssinica (Lam.) Cogn. Socio-economic status of the households and ecological requirements was found to be an important factor affecting the use, management and conservation of the crop. The difference in level of education had no impact on conservation and use of Coccinia abyssinica. It was also observed that the older informants were more knowledgeable than the younger ones, as they knew much more about the different local cultivars and values of use. Data of the mean values of all experimental units were subjected to analysis of variance for RCBD. Flower width (61.22%) showed high heritability and medium heritability was recorded for flower length (52.24%), indicated that such characters were least affected by environmental modifications so that; selection based on phenotypic performance would be reliable. Low heritability were recorded for traits like root length (33.72%), Leaf width (21.53%), total root yield (20.6%), leaf length (17.19%), root diameter (8.33%) and low heritability were recorded for other to indicate environmental effect that constitutes a major portion of the total phenotypic variation signifying that management practice is better than selection to improve those traits. Genetic advance as percentage of the mean ranged from 2.45% for leaf length to 77.08% for flower width. Within these range a relatively high genetic advance as percent of the mean was observed for flower length (57.72%) and flower width (77.08 %). High value for heritability and genetic advance of the characters in current study provide information for the existence of wider genetic diversity among anchote landraces which offers high chances for improving several traits of the crop through simple selection. Cluster analysis showed that four divergent groups were formed. Each cluster known by their highest and lowest mean value and it is helpful for easy selection of parents with the desired traits for hybridization or selection program.
