Demand of rice as a staple food in Indonesia continues to increase, but the capacity to produce more rice paddy is limited. Meanwhile, the use of Gogo-dryland rice could help to meet the demand, but the contribution of Gogo-dryland rice was lower than Paddy-field rice. Therefore, need to develop Gogo-dryland rice which have drought tolerance and high yield potential. The objectives of the study were to evaluate the performance of F1 hybrid derived from the crossing of Gogo-dryland rice (Situ Bagendit and Towuti) x Paddy-field rice (Ciherang and Cibogo) and to identify pure hybrid of F1 using simple sequence repeat (SSR). The research was conducted in screen house and plant biotechnology laboratory of Brawijaya University, Malang, Indonesia. Ninety six of F1 plants derived from four combined crosses were evaluated in morphological and agronomic characters. To identify pure hybrid, four primers i.e. RM219, RM260, RM525, and RM318 were used. The result showed that there was significant difference in both morphological and agronomic characters between F1 and their respective female parents except in plant height variable. The F1 hybrids with Situ Bagendit as female parent have similar band with the male parents (Paddy-field rice). In contrast, Towuti as female parent produced F1 hybrids which have similar band with the female parent itself. The F1 hybrids which similar with male parents can be considered as the true hybrid. The information generated from this study can be a valuable information to develop new rice cultivar with drought tolerance and high yield potential. © 2017 author (s).
