The present invention relates to seed products from seeds having low
starch (e.g., 25-40%) and high .beta.-glucan (e.g., 10-25%), particularly
from seeds with moderate amylose levels, particularly from mutated seeds
(e.g., in which the AGPase gene is mutated), methods of preparing such
products, methods for screening for seeds, .beta.-glucan preparations and
novel seeds having low starch and high .beta.-glucan.
