Abstract

Meiotic behaviour of a monosomic-trisomic (2n−1+1=20) of Coix gigantea (Poaceae) showed that, although there are a few segregational irregularities, it is essentially mostly normal. The plant is healthy and semifertile, and through the formation of viable male and female gametes of variable chromosomal constitution it is expected to produce simple and complex aneuploids in its progeny. The origin is believed to have been through nondisjunction of two bivalents, a large and a small in a diploid.
