Defective crown; lethal; cultured embryos not obtained. Defective crown, irregularly wrinkled, crumpled and/or dented, opaque, nonviable kernel. Endosperm of floury starch with an uneven layer of corneous starch; degenerate embryo with defective shoot apical meristem is blocked at Abbe and Stein (1954) coleoptilar stage. Cultured embryos produce only scutellar callus. Genetic 2005 2 coordinates determined from these recombination and map data: T1-2(4464) dek23; dek16 -0- dek23; see MaizeGDB ID:104511; 86904. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
