ABSTRACT<br /><br />The breeding of rainfed rice tolerant to drought can be accomplished using anther culture. The objectives of this research were to determine regeneration abilities of six F1 anther culture and its acclimatization ability. The experiment was arranged in completely randomized design with 14 replications. The treatments consisted of six F1 derived from crossing:  INPARI 18 x IR83140-B-11-B (G1), INPARI 18 x B12825E-TB-1-25 (G2), INPARI 18 x IR87705-14-11-B-SKI-12 (G3), INPARI 22 x IR83140-B-11-B (G4), Bio-R81 x O18b-1 (G5), Bio-R82-2 x O18b-1 (G6). Media for callus induction was based on N6 medium + 2.0 mg L-1 NAA + 0.5 mg L-1 kinetin + 1.0 mM putresin + 60 g L-1 sucrosa, media for regeneration was based on MS + 0.5 mg L-1 NAA + 2.0 mg L-1 kinetin + 1.0 mM  putresin, and media for rooting was based on  MS + 0.5 mg L-1 IBA + 30 g L-1 sucrosa. The result indicated that all six F1 had different ability in anther culture. Bio-R82-2 x O18-b1 (G6) and  Bio-R81 x O18-b1 (G5) F1 genotype had good response both of callus induction and plant regeneration. These two F1 genotypes also gave the highest ratio of green planlet production to number of anther inoculated (GP:AI) were 5.50% and 4.65%,  respectively. In this research, there were identified doubled haploid plants were developed from 4 F1 derived cross namely G2 (2 plants), G3 (4 plants),  G5 (21 plants), and G6 (26 plants).<br /><br />Keywords: Callus induction, doubled haploid, rice<br /><br />

Anther culture technique is the most viable and efficient method of producing homozygous doubled haploid plants within a short period. However, the practical application of this technology in rice improvement is still limited by various factors that influence culture efficiency. The present study was conducted to determine the effects of two improved anther culture media, Ali-1 (A1) and Ali-2 (A2), a modified N6 medium, to enhance the callus formation and plant regeneration of japonica, indica, and hybrids of indica and japonica cross. The current study demonstrated that genotype and media had a significant impact (p < 0.001) on both callus induction frequency and green plantlet regeneration efficiency. The use of the A1 and A2 medium significantly enhanced callus induction frequency of japonica rice type, Nipponbare, and the hybrids of indica × japonica cross (CXY6, CXY24, and Y2) but not the indica rice type, NSIC Rc480. However, the A1 medium is found superior to the N6 medium as it significantly improved the green plantlet regeneration efficiency of CXY6, CXY24, and Y2 by almost 36%, 118%, and 277%, respectively. Furthermore, it substantially reduced the albino plantlet regeneration of the induced callus in two hybrids (CXY6 and Y2). Therefore, the improved anther culture medium A1 can produce doubled haploid rice plants for indica × japonica, which can be useful in different breeding programs that will enable the speedy development of rice varieties for resource-poor farmers.

Kultur anter merupakan salah satu teknologi haploid penting dalam produksi tanaman haploid ganda dan berhasil diaplikasikan pada berbagai jenis tanaman, namun aplikasi pada Anthurium belum pernah dilaporkan. Penelitian dan pengembangan kultur anter Anthurium yang difokuskan untuk mempelajari pengaruh glutamin dan serin terhadap induksi, pertumbuhan, dan regenerasi kalus dilakukan di Laboratorium Kultur Jaringan Balai Penelitian Tanaman Hias dari bulan Januari sampai dengan September 2008. Tujuan penelitian ialah mengetahui pengaruh kombinasi konsentrasi glutamin dan serin terhadap induksi, pertumbuhan, dan regenerasi kalus pada kultur anter Anthurium. Spadik Anthurium andraeanum cv. Tropical, kalus hasil kultur anter serta medium Winarto dan Teixeira digunakan dalam studi ini. Glutamin dan serin pada konsentrasi 0, 250, 500, dan 750 mg/l diuji dalam percobaan ini. Percobaan disusun menggunakan rancangan acak lengkap pola faktorial dengan empat ulangan. Hasil studi menunjukkan bahwa penambahan glutamin dan serin pada medium terseleksi belum memberikan pengaruh yang signifikan terhadap induksi, pertumbuhan, dan regenerasi kalus. Glutamin pada konsentrasi 250 mg/l menginduksi potensi tumbuh anter hingga 48% dengan 21% anter beregenerasi dan 1,3 anter per perlakuan membentuk kalus. Sementara serin pada 500 mg/l merupakan konsentrasi yang paling potensial dalam induksi kalus dengan 55% potensi tumbuh anter, 24% anter beregenerasi, dan 1,4 anter per perlakuan membentuk kalus. Glutamin 250 mg/l merupakan konsentrasi terbaik dibanding konsentrasi yang lain dalam mendukung pertumbuhan dan regenerasi kalus. Perlakuan tersebut tanpa serin mampu menginduksi potensi pertumbuhan kalus hingga 77% dengan volume kalus mencapai 237 mm3 dan empat tunas dihasilkan per eksplan. Sementara perlakuan serin justru mereduksi pertumbuhan dan regenerasi kalus dan menstimulasi senesensi kalus yang berdampak pada pencoklatan dan kematiannya. Dari hasil penelitian ini dapat disarankan penggunaan glutamin dibanding serin dalam meningkatkan keberhasilan kultur anter Anthurium.<br /><br /><br /><br />Anther culture is one of important haploid technologies in producing double haploid lines and successfully applied in many plants, while the application in Anthurium is not reported yet. Research and development in anther culture of Anthurium focusing on studying the effect of glutamine and serine on callus induction, growth, and its regeneration was conducted at Tissue Culture Laboratory of Indonesian Ornamental Crops Research Institute from January untill September 2008. Objective of this study was to know the effect of glutamine and serine on callus induction, growth, and its regeneration in anther culture of Anthurium. Spadix of Anthurium andraeanum cv. Tropical, callus derived from anther and Winarto and Teixeira medium were utilized in the study. Glutamine and serine of 0, 250, 500, and 750 mg/l were tested in the experiments. Factorial experiment was arranged by completely randomized design with four replications. Results of the study indicate that addition of glutamine and serine in selected culture medium gave moderate significant effect on induction, growth, and regeneration of callus. Glutamine in 250 mg/l induced potential growth of anther up to 48% with 21% regenerated anthers and 1.3 anthers per treatment producing calli, while 500 mg/l of serine was better concentration in callus formation with 55% potential growth of callus, 24% regenerated anthers and 1.4 anthers per treatment producing calli. In growth and regeneration of callus, supplementation of serine reduced callus capacity in growth and production of shoots and stimulated callus senescence causing browning and death of it, while 250 mg/l glutamine exhibited positive effect on them. The treatment without serine was able to induce potential growth of callus up to 77% with 237 mm3 per callus and four shoots produced per explants. Results of the study suggest application of glutamine rather than serine in improving anther culture of Anthurium.<br /><br />
