Cytological study in some members of tribe paniceae (poaceae) from Rajasthan

Abstract

The present study is a part of our research project on the meiotic studies of some Monocots from the Rajasthan area. Rajasthan, the hot desert of India, has low biodiversity. The present paper deals only with the 19 species of the tribe Paniceae out of these 3 species, viz., B. mutica (n=14), Eriochloa procera (n=27) and Panicum typheron (n=9), are new euploid chromosome reports (two for the world and one for India). Out of these, abnormal meiosis is found in Brachiaria reptans (n=7), B. mutica (n=14), Eriochloa procera (n=27) and Paspalum paspalodes (n=30), whereas meiotic course is normal in the others.
