Information related to genetic resources of castor plant is little known. Molecular approaches can be used to analyze variation of germplasm. Molecular-based analysis is strongly influenced by quantity and purity of DNA sample as template. Therefore, this research aimed to isolate genomic DNA of castor bean using Genomic DNA Mini Kit (Plant) GeneAid. The result showed that extraction DNA total produced DNA bands . Five individuals show thin fragmen and six individuals show thick fragment.enisolation DNADNA totalcastor beanRicinus communis LArticle
