Inheritance of an Albino-Virescent Leaf Mutant in the Cultivated Peanut (Arachis hypogaea L.)

Abstract

An Albino-Virescent Leaf mutant was recently found in an advanced Georgia peanut (Arachis hypogaea L.) breeding line, GA 082524. This breeding line was derived from the cross of ‘Georgia-02C' x (‘Georgia-01R' x ‘COAN'), none of which have exhibited any mutant phenotypes in the past. The Albino-Virescent leaf mutant was selected and reciprocal crosses made with GA 082524 to determine the inheritance of this unusual chlorophyll deficiency. F1 and F2 data indicated a single recessive gene, avl, controlled the Albino-Virescent leaf trait. Chi-square analysis indicated a good fit to the expected 3:1 segregation ratio. No maternal or cytoplasmic effects were detected among the progenies from reciprocal hybridization.
