Abstract

Rice (Oryza sativa L.) is a staple crop in Indonesia. Despite its main importance for the Indonesia’s food supply, the production is influenced by several factors. One factors which influence rice yield is drought stress. The experiment was conducted in two fields namely Talok village and Jatimulyo village. The parental lines were gogo-dryland and paddy-field rice types. In Talok village, the success rate of hybridization ranged from 47% to 85% while in Jatimulyo village 16.33% to 38.67%. The result of student T-test for the width of brown rice in Talok village field showed a significant difference through Situ Bagendit x Ciherang and Situ Bagendit x Cibogo. While in Jatimulyo village field, student T-test for the length of brown rice showed very significant difference through Inpago x IR64 and Inpago x Ciherang. Besides, the width of brown rice showed very significant difference through Inpago x IR64 and Inpago x Ciherang.
