Cytogenetical studies inSaccharum spontaneum

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

Karyotype and meiosis were studied in several clones ofSaccharum spontaneum with chromosome numbers 2n=40 to 2n=126. Differences in the karyotype was observed between different clones with the same chromosome number. Karyotype symmetry/asymmetry has been indicated. The number of chromosomes in different cells of the same plant varied in many clones at meiosis and first pollen grain mitosis. Occurrence of B chromosomes in pollen mother cells and pollen grains were noticed in a few clones. At meiosis univalents, heteromorphic bivalents, secondary association of bivalents, etc., were noticed and their importance discussed.
