Abstract
Grasses from Thailand closely related to sugarcane have the following chromosome numbers: In Saccharum spontaneum L. 2n=78, 80 and 96. Aneuploid individuals occur in each type. Two plants among 96-chromosome collections have 88 chromosomes and could be hybrids between 96- and 80- chromosome types. In Erianthus arundinaceus (Retz.) Jesw. 2n=60. In Narenga porphyrocoma (Hance) Bor 2n=30. In a species of Sclerostachya not yet described, 2n=30.
Grasses from Vietnam related to sugarcane have the following chromosome numbers: In Saccharum spontaneum 2n=80, and in Erianthus bengalense (Retz.) Stewart 2n=60.
