Meiotic behavior and chromosomal association of two diploid mulberry varieties, (Moraceae)

Abstract

Two diploid mulberry varieties namely, V₁ and M₅ have been analyzed for detailed meiotic studies. Based on the chromosome configuration and other meiotic behavior x = 14 have been considered as basic number of the genus Morus. Meiosis shows marginal differences. Various meiotic abnormalities like occurrence of one mega chromosome pair at diakinesis, chromosomal bridge and chromosomes grouped more than four poles at anaphase II have been observed.
