The experiment was conducted to investigate the performance of three different genotypes (BARI Sarisha-6, BARI Sarisha-8, and BARI Sarisha-11) in two different media viz., MS and B5 with different concentrations of phytohormone (2, 4-D) for callus induction from uninucleate stage anthers of Brassica and subsequent plant regeneration in MS media with different concentrations of phytohormone (BAP and NAA). Among the genotypes, BARI Sarisha-8 showed the best performance for all the parameters of callus induction. The performance of BARI Sarisha-6 was poor compared to others. Maximum rate of callus induction (%) was observed in MS + 0.5 mg/L 2, 4-D followed by B5 + 0.5 mg/L 2,4-D. The media combination MS + 1.0 mg/L BAP 0.3 mg/L 2,4-D showed the best performance for maintenance of calli. Significant variations were observed among the genotypes and media composition for shoot regeneration. Among the genotypes, BARI Sarisha-8 showed the best performance for shoot regeneration followed by BARJ Sarisha-l1. The genotype BARI Sarisha-8 produced higher percent of shoots/calli and required minimum days for shoot initiation. Higher percent calli without shoot were produced by the genotype BARI Sarisha-6. The media combination MS + 2.0 mg/L BAP + 0.5 mg/L NAA showed the best performance for shoot regeneration and required maximum days for shoot initiation.

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 of five varieties of Brassica species, namely BARI Shariaha-7, Tori-7, Agrani, Daulat and Safal were cultured in vitro to observe their regeneration potentiality. Different concentrations and combinations of growth regulators were supplemented in MS medium. The range of callus induction was 12.50-87.50 %. Maximum callus induction (75.00%) was observed on MS +4 mg/L 2, 4-D + 1.0 mg/L BAP. Among the genotypes, BARI Sharisha-7 showed the highest percentage of callus induction (60.42%). Among the treatments, highest percentage of shoot regeneration (75.00%) was observed on MS + 4 mg/L BAP + 1.0 mg/L NAA. BARI Sharisha-7 also showed the highest rate of plant regeneration (66.67%). Root induction was highest (75%) on half strength MS medium supplemented with 1.0 mg/L IBA and 0.5 mg/L NAA. The plantlets with sufficient roots thus obtained were transferred successfully to plastic pots and subsequently to the field. BARI Sharisha-7 and Tori-7 survived easily in the pots as well as in the field but Safal was very poor in survivability both in the pots and in the field.

With different culture conditions and concentrations of growth regulators and supplements, Anther culture technique can be easily employed for the production of haploids under in vitro conditions. Aims: The present study was undertaken with the objective to optimize the development of doubled haploids using anthers for in vitro induction of callus on N6 medium. Place and Duration of Study: The samples (BC2F1 seeds) were raised previously in Skuast-J. From total degree program of 3 years, this work related to tissue culture technique was done in one year from January 2018 to January 2019. Methodology: The effect of levels of 2, 4-dichlorophenoxy acetic acid (2, 4-D) i.e. 0 to 3 mg/L in basal N6 media was observed on callus induction frequency (CIF). The effect of duration of cold pre-treatment was observed on callus induction frequency at 2.5 mg/L of 2, 4-D by giving the cold pre-treatment at 4ºC from 8 to 12 days. Also the effect of different amino acids was checked on callus induction frequency. Results: Highest callus induction frequency of 9.39 per cent was observed in N6 medium fortified with 2.5 mg/L 2, 4-D and lowest callus induction frequency of 2.52 per cent at the concentration of 1.0 mg/L. The cold pre-treatment for 10 days gave highest callus induction frequency of 1.44 per cent and lowest callus induction frequency of 0.44 per cent was obtained at cold pre treatment for 8 days. The highest callus induction frequency of 12.55 per cent was observed in case of media supplemented with 25 mg/L tryptophan and 40 mg/L cysteine and lowest callus induction frequency of 7.18 per cent was observed when media was supplemented with 560 mg/L proline. Conclusion: The cold pre-treatment of 10 days at 4ºC on media supplemented with 2.5 mg/L of 2, 4-D and combination of 25 mg/L tryptophan and 40 mg/L cysteine proves to provide best androgenesis conditions for anthers from BC2F1 population.
