5. An unusual example of a somatic change was found in a plant heterozygous for the translocation T5-9a. The ear on this plant had approximately half the silks green and half red. Other plants from the same cross had green silks, with the exception of two plants having a few red silks and all others green. Although the ear which was about half red and half green was open pollinated, tests are being made to determine if the change was only in maternal tissue.
