Karyological Observations in Musa beccarii var. hottana (Musaceae)

Popis výsledku v původním jazyce

The center of diversity of the genus Musa (Musaceae) is in Southeast Asia, a region not studied in detail and where new species and varieties continue to be reported. Recently, a new variety, Musa beccarii var. hottana was described. To improve its characterization, the chromosome number and genome size of varieties hottana and beccarii were analyzed. Variety hottana had a diploid number of 2n = 18, the same as var. beccarii. This is an interesting finding, as other species of Musa section Callimusa, inwhich M. beccarii has traditionally been included, have 2n = 20. Nuclear DNA amounts (2C) of var. beccarii and var. hottana were estimated to be 1.562pg and 1.645 pg, respectively. These are the largest genome sizes reported so far in Musa. The analysisof the genome structure of M. beccarii may contribute to an understanding of the processes at the DNA and chromosomal levels that accompanied the evolution in the genus Musa.
