| Abstract: |
| Karyotype analysis is first one paper of a series of our cytogenetical research works in sesame with the purpose of identifying the morphologi- cal characteristics of each chromosome bY modified squash techniques using a local variety called Beijing Ba-Wang-Bian as material.The results may be concluded as follows: 1.The sesame karyotype is 2n=2x=26,Among thirteen pairs of homolo- gous chromosomes,one pair carries satellites. 2.The morphological indices of chromosome show that chromosome length, relative len... |
