Abstract:

In the breeding work to improve the characters of“Opaque-2”cornendosperm,it is necessary to analyze the hybrid progeny in order topick out the kernels of hard endosperm which contains high lysine.Thezein content of normal corns is about twice as much as high-lysine corn.The difference of zein content among the kernels can be distinguishedaccurately with the sensitive colorimetric method of Folin-phenol.Sothe high-lysine kernels can be picked out.
