Glassy, tarnished endosperm; affects soluble starch synthase and branching enzyme IIa. Kernels sometimes shrunken or dented (strongly so in double recessive with wc1). Genetic 2005 10 coordinates determined from these recombination and map data: oy1 -21.3- du1; zn1 TB-10L26 du1 bf2 li1 g1; du1 -0.5- TB-10Lb; zn1 du1 TB-10L22 bf2 li1 g1; zn1 du1 TB-10Lb bf2 li1 ms10 g1; see MaizeGDB ID:9017299; 136868; 935455; 136864; 299163. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
