Interpretive Summary:

Technical Abstract: The 1997 Rhizoctonia disease nursery, commercial test included 21 entries, with six replications. Plants were scored on a scale of 0 to 4, with 0 = no lesions found, 1 = up to 25% of the root covered with lesions, and 4 = 76 to 100% of the root covered with lesions. Dead or missing plants were scored as 4. The susceptible check was US H20, whereas FC 701/5 and FC 712 served as resistant checks. A few of the entries appear to have resistances to Rhizoctonia that range from better than most, to very good. One entry, designated 96RR, scored as having disease resistance to Rhizoctonia superior to that of any other entry. This line is germplasm selected at East Lansing, MI, and is scheduled for release in 1998.
