Diversity of cucumber accessions in Oman

Twenty-four local accessions of cucumber were collected from the four regions of Oman, to evaluate genetic diversity based on morphological traits. The Shannon-Weaver diversity index analysis revealed the presence of genetic diversity based on morphological traits among the accessions both rationally and regions. The diversity index for agronomic, fruit and seed characters showed that Omani cucumber accessions had higher diversity (H) for all characters. Two main clusters were obtained. One group was further sub-divided into five sub-groups. The results showed significant genetic diversity in Omani cucumber accessions collected from different regions of Oman. This diverse indigenous cucumber gene pool may signify the potential for future cucumber crop improvement in Oman.
