Abstract: | The karyotypes of Renanthera storiei and Trichoglottis fasciata and the meiotic behavior in their hybrid were investigated. Considerable differences in chromosome morphology were observed for the two species. The karyotype of R. storiei was more asymmetrical with a lower mean F percentage than that of T. fasciata. Also, variation in the largest pair of chromosomes as well as in the satellite chromosomes was apparent. Meiosis in the hybrid was highly irregular. Observations on karyotypes and meiotic behavior indicate a more distant relationship between Trichoglottis and Renanthera than among Renanthera, Arachnis, and Vandopsis. |
