Silks salmon color with P1-rr, brown with P1-ww. Classification good in presence of pericarp color, otherwise difficult. See Emerson et al.(1935 Cornell AES 180) for table of interactions. Genetic 2005 6 coordinates determined from these recombination and map data: oro1 su2 sm1 TB-6Lb; (sm1 -4- pt1); pl1 -9- sm1 -14- tan1; see MaizeGDB ID:301239; 935466; 935832. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
