Comment	See 'Gene_Class : Spelt' for comments regarding the Q, C, and S1 genotypes of hexaploid wheats and the durum and carthlicum groups. Sphaerococcum-like tetraploid wheats have been reported (93, 324, 908, 910), but comparisons between them, or with s2, have not been made. Whereas Schmidt & Johnson (907) reported a single recessive factor controlling the sphaerococcum character in tetraploid wheat, Joppa (442), using the same stock, found that two recessive genes were necessary to produce this phenotype.
