collapsed opaque kernel Selfed yellow flint ear segregating for variably collapsed and opaque cpo*-N627D dek6 mutant kernels. Weak green seedling viable only in embryo culture.

collapsed opaque kernel Two colorless flinty selfed ears segregating for, cp*-N931, (dek18). Top, mature ear showing collapsed floury mutant kernels. Bottom, immature ear (17 days) showing small mutant kernels with translucent endosperms. Drying produces varieable amounts of collapsing

collapsed opaque kernel excised immature dek18-N931A mutant embryos cultured on normal kernel extract, basal, enriched, or ammonia free enriched media showing green amorphous callus tissue on all media and a few roots and primitive shoots on ammonia free enriched medium.

collapsed opaque kernel Excised immature, o*-N627D dek6, defective embryos grown on kernel extract, basal and enriched media, showing poor variable growth on all three media, but little root growth in enriched
