4. Possible new genes from sb crosses:

• tw_sh -- an adherent showing in both the seedling (causing it to be twisted) and the tassel. Viability good. Classification good.
• mi_sh -- a semi-dwarf with compact tassel, rather stiff leaves, small seeds. Viability good. Fertility good. Classification good except with lg.
• g_sh -- a vigorous golden, showing golden late. May be g₂, for it showed about 30% recombination with a.
