Genotypes of three resistance loci in parents of RILs and donors of resistance

Cultivar/line	SCN resistance			rhg1		Rhg4		rhg2
	race 1	race 3		Sat_210		Sat_162		Sat_123	Satt453a
PI 84751	R	R		P		P		P	P
Gedenshirazu	S	R		G		G		G	G
P1: Tokei 758	S	S		other		other		other	other
P2: To-8E	R	R		P		P		G	G

P, PI 84751-type; G, Gedenshirazu-type. Note that PI 84751 (resistant to SCN race 1) own rhg1, Rhg4 and rhg2, and that Gedenshirazu (resistant to race 3) own only rhg1 and rhg2.
