Abstract
The varieties of Avena sativa L. var. RO-19 and Avena sativa L. Kent were collected from Birsa Agriculture University, Ranchi, Jharkhand for the studies on karyotype and stomatal characters. The varieties under investigation were reported to show hexaploid set of 42 chromosomes (2n = 2 x = 42) and were asymmetrical in nature. Graminaceous type of stomata were found in these varieties of Avena sativa L. with variation in size and distribution. The stomatal index was found to be maximum in Avena sativa L. var. RO-19 at apex portion of dorsal surface stomatal length and width was found to be maximum in Avena sativa L. var. Kent at apex portion of ventral surface.
