Mutations for chlorophyll deficiency were identified in an experiment designed to -recover new mutations in the Asgrow Mutable line as evidence for transposition of a mobile genetic element. A detailed protocol for the experiment is presented in the preceding research note (Groose and Palmer, 1987). Each of three independent mutations that are described below was discovered in a sandbench test of a different F11 family, each of which had descended from a different F9 plant of the Asgrow Mutable line
