【 摘 要 】

The cross between Black Rice and Mentik Wangi rice varieties was carried out to obtain black rice breeding lines with good palatability and aromatic fragrance. In this research, F4 breeding lines derived from the cross of Black Rice and Mentik Wangi varieties were evaluated for their agronomic performances and selected to be F5 generation. The research was conducted in paddy field of Mersi Village, East Purwokerto District, Banyumas Regency, Indonesia, from July-November 2016. Augmented Complete Randomized Block Design with three replicates was used to arrange the F4 breeding lines and the check varieties of Black Rice, Mentik Wangi, IR 36 and Red Rice varieties. The results showed that plant height, number of productive tillers, number of seeds per panicle and 1000 seed weight of F4 breeding lines are uniform, while the flowering date, total tillers, panicle length and seed weight per hill still transgressively segregate. Based on the segregating agronomic characters, six breeding lines were selected to be continued to become F5 generation, namely: PHMW 48211431, PHMW 482171867, PHMW 48291349, PHMW 48211447, PHMW 4829134102, PHMW 48724850. Analysis on amylose content showed that the selected breeding lines have low to moderate amylose content.
