Production of haploids from anther culture of banana (Musa balbisiana (BB))
We report here, for the first time, the production of haploid plants of banana #Musa balbisiana# (BB). Callus was induced from anthers in which the majority of the microspores were at the uninucleate stage. The frequency of callus induction was 77%. Callus proliferation usually preceded embryo formation. About 8% of the anthers developed androgenic embryos. Of the 147 plantlets obtained, 41 were haploids (n=x=11). The frequency of haploid production depended on genotypes used: 18 haploid plants were produced from genotype 'Pisang klutuk', 12 from 'Pisang batu', seven from 'Pisang klutuk wulung' and four from 'Tani'. The frequency of regeneration was 1.1%, which was based on the total number of anthers cultured. Diploid plants (2n=2x=22) were also observed in the regenerated plants. The haploid banana plants that were developed will be important material for the improvement of banana through breeding programmes.
