Abstract

Replacement of non-fragrant-native badh2 gene with mutated badh2 of fragrant rice is an alternative to engineer new fragrant rice varieties with good agronomic traits as those of non-fragrant. Fragrant gene (mutated badh2) of Mentik wangi donor was introgressed into non-fragrant Ciherang host through site-directed crossing. Mentik Wangi was crossed with Ciherang, and the progeny was further backcross until BC3F1. Bradbury marka-assisted PCR was used to select progeny in every cross and backcross generation. Ciherang, Mentik Wangi, and their cross/backcross showed different PCR profiles. The statues of badh2 gene (native/mutated), as well as alleles (homozygote/heterozygote) between samples were identified. Mutated badh2-introgression was also observed within the selected heterozygote cross or backcross progenies (Fl, BCl, BC2, and BC3), indicated successful transfer of mutated badh2 gene from donor to host.

Abstract

This research applied various badh2.7 and badh2.2 fragrant markers (Bradbury et al., 2005b, Lang and Buu 2008, Shi et al., 2008, Sakthivel et al., 2009) on popular Indonesia non-fragrant (Ciherang, Fatmawati) and fragrant (Pandan wangi, Rojo Lele, Mentik Wangi, Gunung Perak, Pulu mandoti, Pare Kembang, Sintanur) rice varieties. For comparison, IR64, Nippon bare and Taipei 309 were included. Rice DNA samples were isolated from young  leaves, and PCR amplified using each of those fragrant markers. Results using all badh2.7 markers were consistently supported the existence of 2 group badh2.7 mutation pattern, while the use of badh2.2 marker indicated that there was no ex on 2 mutation. Badh2.7 sequence analysis of non-fragrant Ciherang, and aromatik member of group 1 (Pandan Wangi), as well as group 2 (Mentik Wangi) showed different mutation pattern.

Abstract

Marker-assisted PCR has been considered as the most potential method for fragrant selection. RM223 is the only suitable marker to identify mutated badh2 gene of Pandan Wangi. This research applies RM223-assisted PCR in the introgression of fragrant gene (mutated badh2) of Pandan Wangi variety, to engineer non-transgenic fragrant variety with good agronomic traits as those of Ciherang.  Gene introduction was carried out through site-directed crossing; Pandan Wangi was crossed and backcrossed to Ciherang until heterozygot BC5F1, followed by selfing to obtain homozygot BC5F2.  RM223-assisted selection was conducted in each cross and backcross generation. RM223 was able to identify native, mutated and heterozygot badh2 of Ciherang, Pandan Wangi, and their cross/backcross progenies, respectively. Therefore, the introgression of mutated badh2 within progenies were observed, as well as the statues of badh2 gene (native/mutated) and alleles (homozygot/heterozygot). Further backcross and selfing to obtain BC5F2 is in progress.
