Chromosome Counts through Male Meiosis in Seven Species of Genus Elymus L. (Tribe Triticeae: Poaceae) from North West Himalayas, India

摘要

Present study explores the meiotic chromosome numbers in seven species of the genus Elymus from Himachal Pradesh and Uttarakhand, India. The study adds the first chromosome number of E. gangotrianus (n = 14+0-2B), besides adding chromosome numbers for Indian taxa of E. himalayanus (n = 21), E. jacquemontii (n = 14), E. schrenkianus (n = 21) and E. schugnanicus (n = 14). In the genus Elymus polyploidy might have a role in its chromosome evolution.
