Anther culture of the African violet, Saintpaulia ionantha (Gesneriaceae), produces haploid plants directly from anthers at a low frequency. Successful anther culture for either this species or family has not been previously reported. Anthers between 3 mm and 5 mm in diameter are most suitable for culture. Root formation must be induced by the addition of indoleacetic acid to the medium.

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 />

The anther culture response in Solanum commersonii (2n = 2x = 24, 1EBN) and S. chacoense (2n = 2x = 24, 2EBN), two wild potato germplasm resources was studied to obtain haploid plants. Three accessions from each of the two species and 3200 anthers from each genotype were cultured. Authors assessed different culture media; ascorbic acid, L?cysteine and silver nitrate (AgNO3) were included to prevent browning of anther cultures. Addition of AgNO3, was effective to induce embryogenesis. The clones from S. commersonii showed different embryogenic response to androgenesis. However, the three accessions from S. chacoense did not induce any embryo in the same conditions. Ploidy level of the regenerated clones was estimated by flow cytometry and confirmed by chromosome counts. This is the first report of haploid plants obtained from anther culture in S. commersonii, with important implications in sequencing efforts and potato breeding.Plant Tissue Cult. & Biotech. 26(2): 159-173, 2016 (December)
