| 英文摘要 |
Cheesman, Simmonds, Dodds, et. al. have published a series of papers under the subject of ''Genetical and cytological studies of Musa'' in the Journal of Genetics from 1932 on. They also have conducted the breeding program of bananas at Trinidad, British West Indies. Same work has been carried out in Jamaica. Edible bananas are highly vegetatively parthenocarpic and sterile. The parthenocarpy is generally believed due to the higher auxin concentration in the developing. ovary. They belong to the subgenus Eumusa of the genus Musa. White recorded the basic chromosome number of Musa in multiples of 4, while Cheesman and Larter found that the haploid chromosome number in Eumusa is 11. |
