Chromosomal aberrants and gene mutations inNicotiana obtained by grafting

  • Dontcho Kostoff
Article

Summary

  1. 1.

    Irregular m⎵oses were observed in the p.m.c.’s of the scions in certain intergeneric graft unions.

     
  2. 2.

    Such scions produced a high percentage of abortive pollen grains and pollen grains with increased numbers of chromosomes.

     
  3. 3.

    Chromosomal aberrants (monosomic, trisomic, triploid, hypertriplont, etc.) and gene mutations were found in the generations following the selling of the flowers of the scions having abortive pollen grains. The controls gave only normal plants.

     

The author is indebted to Mr J. Kendall for revision of the manuscript.
