Cytological Studies in the North Indian Grasses

Abstract

Cytological studies in 49 taxa belonging to 27 genera and 39 species of grasses from the plains and hills of North India have been carried out. One species Agropyron striatum has been cytologically investigated for the first time and new chromosome numbers have been made available for 8 more species. These species are: Agrostis semiverticillata (n=21), Helictotrichon virescens (n=21), Dactyloctenium aristatum (n=20), D. sindicum (n=10), Festuca modesta (n=7), Sporobolus.fimbriatus (n=27), Oryzopsis munroi (n=12), and Paspalidium flavidum (2n=44). Accessory chromosomes have been reported for the first time in Phleum himalaicum, Agropyron striatum, Polypogon fugax and phalaris minor.
