1115BC1F2 --Toiku-223/Tokei-871//Toiku-233--, P1: Toiku-233 (race 3), P2: Tokei-871 (race 1).
“A” indicates the same genotype as “Toiku-233” (race 3), “B” indicates the same genotype as “Tokei-871” (race 1), “H” indicates heterozygous, and “C” indicates the same genotype as Gedenshirazu.
“Ge” indicates “Gedenshirazu”, and “P” indicates “PI84751”.
From our preliminary experiments, it was estimated that all lines exhibit resistance to race 3 in this cross.
