Revolute-Leaf, a New Completely Dominant Mutant in Peanut

A Revolute-Leaf mutant plant was discovered in an advanced Georgia peanut (Arachis hypogaea L.) breeding line, GA 112702. The mutant had leaf margins that curve downward on each of the four small light-green leaflets. Two cross combinations were used to determine the inheritance of this new mutant. F1, F2, and F3 segregation data strongly supported a single completely dominant gene, designated Rev, controlling the inheritance of the Revolute-Leaf mutant. The F2:3 homozygous revolute-leaf individual plants had shorter mainstem heights, narrower leaflet length and width, narrower canopy width, reduced pod and seed weights, but similar SMK percentages compared to the F2:3 homozygous normal leaf plants resulting from the same closely related cross combination (GA 112702 x Revoluted-Leaf mutant).
