Male Meiosis in Some Grasses of the Tribe Paniceae

II. Genus Panicum from North-Eastern India

Abstract

Present work includes cytological studies on 13 species of the genus Panicum Linn. from North-Eastern India. Panicum auritum (2n=30, n=30, 36), P. cambogiense (n=9) and P. humidorum (n=18) have been cytologically reported for the first time. New chromosome numbers have been detected in P. notatum (n=36), P. repens (n=30), P. trypheron (n=21) and P. walense (n=18, 36). Evolution of base number x=9 from x=10 and polyploidy in the genus have been discussed.
