Abstract
The inheritance of six chlorophyll deficlent mutants of lettuce (Lactuca sativa L.) was studied. Chlorophyll deficlent-3 (cd-3) is recessive and epistatic to light green (Ig). Chlorophyll deficlent-4 (cd-4) is recessive and linked to an anthocyanin gene. Previously described virescent (vl) is epistatic to cd-4. Dappied (dap) is a recessive allele. Dappled and sickly (sl) together appear to be lethal. Virescent is epistatic to dappled and dappied is epistatic to light green. Chlorophyll deficient-5, -6, and -7 (cd-5, cd-6, cd-7) appear to be unlinked recessive alleles, although cd-5 and cd-6 may possibly be allelic. Chlorophyll deflclent-5 and/-6 are both epistatic to cd-7.
