Abstract
Phleum pratense L., the only species of Phleum that is of economic importance, is found in all temperate regions of the world.
Cytogenetic evidence, in some cases, indicates the autopolyploid nature of P. pratense.
Several anomalous cytological behaviors such as heavy walled coenocytes, neocentric chromosomes, uncoiled chromosomes, "cross-bridges" at second division, "globular" bodies, and B-chromosomes have been reported in timothy. Some of these behaviors appear to be related to sterility.
Genetic work involving a study of chlorophyll deficiencies suggests hexasomic and tetradisomic modes of inheritance.
Relationships among height, vigor, and fertility following cross- and self-pollination are discussed.
