Disease reaction of plants with the minimal or large (4.2 Mb) I-3 introgressions challenged with Fol3

Breeding linez	I-3 introgressiony	Total no. plants	Healthy (%)
Fla. 8814	None	119	0
	Large	119	98
	Minimal	118	98
Fla. 7946	Large	126	98
	Minimal	126	100
Horizon	None	128	1
Bonny Best	None	128	0

^ZThe minimal I-3 introgression was backcrossed into Fla. 8814 which has a large I-3 introgression; and the resulting near isogenic line (NIL) was compared with Fla. 8814 and with an Fol3 susceptible NIL of Fla. 8814. The minimal I-3 introgression was also backcrossed into Fla. 7946 which has a large I-3 introgression; and the resulting NIL was compared with Fla. 7946. Horizon and Bonny Best are Fol3 susceptible controls

^y“Large” indicates the NIL homozygous for the large (4.2 Mb) I-3 introgression, “Minimal” indicates the NIL homozygous for the minimal (140 kb) I-3 introgression
