Abstract

Three mulberry genotypes viz., MR2, C763 and Morus macroura were analyzed for the stomatal frequency and karyotypic attributes. MR2 and C763 were found to be diploids with somatic chromosome number of 2n=28, while variety Morus cathyana revealed tetraploid chromosome number of 2n=56. Somatic chromosomes measured 1.26 to 2.86 µm in length. Karyotypes of these taxa are symmetric. Only metacentric and sub-metacentric chromosomes are found in the complement. Stomatal frequency was found to be high in diploid mulberry varieties compared to tetraploid variety.
