Abstract:
The chromosome number and genome size of Musa formosana (Warb.) Hayata were analyzed. M. formosana had a diploid number of 2n = 22 and is placed in section Eumusa to conform to the previous morphological studies. Nuclear DNA content or genome size of M. formosana was estimated to be 1.387 pg or 669.23 Mbp per 2C, which was larger than that of A and B genome by 18% and 26%, respectively. The difference in genome size estimated by flow cytometry can discriminate different genomes, which is reliable to identify species and to predict the genome constitution of their hybrids.
Key words:Musa formosana, Chromosome number, Genome size, Flow cytometry, Wild banana
