SINCE the determination ofsomatic chromosome number as2n=24 in tomato by Winkler
(1909) extensive studies have been made of the pachytene chromosomes of tomato by
several workers (Lesley and Lesley, 1935; Lesley, 1938; Brown, 1949; Barton, 1950;
Gottschalk, 1951, 1954). However, very little attention has been given to the study of
somatic chromosomes of cultivated tomato and related species as the somatic chromosomes are small, the largest being about 3fJ (Rick and Butler, 1956), and do not lend
themselves to critical study of their morphology. Utilizing a squash technique, which
gives preparations revealing clearly the morphology of the chromosomes, karyotypes of
some Lycopersicon species have been studied and the results and conclusions are
presented in this paper.
