Differences in pedicel length of tomatoes are comonly observed. Observations made in 1959 at Riverton, New Jersey, revealed that some entries had longer pedicels than others. The entries were adjacent in the field and it did not appear that the differences could be caused by fertility or other environmental factors. Measurements were made from the joint to the attachment surface of detached pedicels from ripe fruit, with the following results:
Pedicel length in millimeters

No crosses have been studied to determine the inheritance pattern, and it is
not known whether or not more than two genotypes will be found. Inspection of
several F2 populations grown for other purposes revealed-pedicel length
differences from 9 to 22 millimeters within populations. Long pedicels were
more distinctly tapered than short pedicels, with the broad end at the fruit
attachment. The symbol "lp" for long pedicel is suggested.
