Germplasm Phenotype:

• CS92951  — ethanolamine-phosphate cytidylyltransferase activity is reduced to 74%. Seedling phosphatidylethanolamine content is reduced by 20%. Dwarf when grown at 8^oC. Earlier senescence of cotyladons and mature leaves. Pale green and smaller seeds. Delay in embryo maturation. Reduced fertility.
• pect1-6  — embryo lethal. Embryos do not develop beyond the octant stage.
