Description
Summary:The genetic improvement of Indonesian cassava is limited by the lack of knowledge about genetic diversity in circulating cassava clones. Good breeding results require information on the Relationship between the clones used. This study aims to study the genetic relationship between several Jember cassava clones through genotype and phenotype approaches. The genetic relationship between 22 cassava accessions was analyzed using RAPD and phenotypically using the key of determination. The genetic Relationship dendrogram results were obtained from 87 DNA bands and 18 phenotypic characters. The genetic relationships were analyzed using similarity coefficients and phenotypic genetic distances. Relationship analysis of 22 cassava accessions based on phenotypic characters yielded similarity coefficients ranging from 0.39 to 0.83. Relationship analysis of 22 cassava accessions based on RAPD markers, resulted in a similarity coefficient of 0.5-1.0, or 55 to 100%.
