✦ Synopsis

Crossability and F1 hybrid fertility were studied using chromosome races (species or infra-specific taxa) representative of "broad-leaved" fescues in sections bovinae and scariosae. Hybrids were also obtained with Lolium multiflorum. The hybridization results, when considered in relation to morphology, cytology, and geographical distribution, support the idea that the Moroccan fescues studied here are more closely related amongst themselves, than to taxa from outside this region. These findings are discussed in relation to the evolution of the polyploids. Material and Methods Details of the species and chromosome races used in the study are *) Present address Madurai Agricultural College P. 0.. Madurai, Tamil Nadu, India. TABLE 1.
