Collapsed endosperm; lethal; cultured embryos green. Large, opaque, variably collapsed, sometimes discolored, nonviable kernel. Endosperm of porous floury starch covered with a thin outer layer of corneous starch. Embryos, varying in size and development, range from degenerate/dry (germless) to near-normal with varyingly degenerate primordia and abnormal (thin, wrinkled or distorted) scutella. Mature embryos lethal. Cultured immature embryos produce light green defective seedlings. Genetic 2005 8 coordinates determined from these recombination and map data: TB-8Lc(8) dek20; see MaizeGDB ID:105601. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
