Cytogenetics of an interspecific hybrid inArachis

  • Published:
Proceedings / Indian Academy of Sciences

Summary

Interspecific crosses between the cultivatedA. hypogaea and a vegetatively propagated species were effected and the cytology of the hybrids was studied.

Details of meiosis in the wild species have been worked out. A number of phenomena in the nature of (i) extrusion, (ii) non-disjunction and (iii) delayed-separation bridges, were exhibited. The similarity of the genomes ofA. hypogaea with those of the seed-propagated and asexually multiplied wild species has been brought out. The probable evolutionary mechanisms concerned in the origin and differentiation of species have been indicated.
