| Summary: | Quality and productivity improvement of the native upland rice cultivars is necessary for more extensively practiced
non-irrigated rice production. This study aimed to genetically and phenotypically characterize the Thai upland rice cultivars that
can serve as potential parents in future rice breeding. Ten upland rice cultivars were morphologically characterized based on their
agronomic traits. The genetic relationship among the rice cultivars was evaluated by HAT-RAPD analysis. The use of arbitrary
primers led to 69.8% of the polymorphic products. Here, we identified some markers that, as a single primer, allowed
differentiation of all cultivars. These markers can be utilized for subsequent investigation of rice diversity. Two dendrograms
constructed based on the phenotypes and polymorphic bands divided the upland rice cultivars of interest into three clusters. This
information will facilitate additional rice breeding programs. |
