Oil yellow
Oily yellow green seedling and plant; many alleles with phenotype & dominance ranging from null deep yellow lethal through white, oil yellow, bright oil yellow green & vigorous yellow green near normal; major effect is absence of chlorophyll b
MaizeGDB reference
Oil yellow
dominant allele: First two leaves of F2 progeny of Oy1-700/+ sibbed (left to right) normal, Oy1 homozygote, and Oy1/+ heterozygote seedlings, showing respectively, normal green, pale yellow lethal and deep yellow green leaves.
oil yellow
First two leaves (left) of dark yellow, oy*-N195, M2 mutant seedling
Oil yellow
allelic interaction: First two leaves of seedlings from the cross of +/oy1 x +/Oy1-700, showing (left to right) yellowgreen; Oy1-700 heterozygote; normal; and bright yellow Oy1-700/oy1 heterozygote.
Oil yellow
Chimera: An immature half-plant chimeric greenish brilliant yellow, Oy1-N1459, M1 mutant origin plant , showing consequence of EMS-induced mutation in two-stranded sperm nucleus of treated pollen grain
Oil Yellow
revertant sector: Two Leaves of an Oy*-N2515/+ heterozygous backcross mutant plant showing yellow green each with a normal green longitudinal chimeral sector indicating some instability of this allele. Possibly of spontaneous origin. Homozygote is yellowish white lethal seedling.
