Inheritance of white-spot testa color trait in peanut

摘要

The white-spot testa color trait has occasionally been found among segregating cross populations in die cultivated peanut (Arachis hypogaea L.). Crosses involving one such true-breeding white-spot selection were made both between and within subspecies of tile cultigen to determine the inheritance of this unusual trait. The F_1, F_2, and F_3 data indicated that two duplicate recessive genes, designated wsp_1 and wsp_2, control tile white-spot trait in peanut.
