Seven advanced FHIA lines were evaluated (FHIA-01, FHIA-02, FHIA-17, FHIA-18, FHIA-21, FHIA-23, and FHIA-25)
BLS
Gauhl’s modification of Stover’s scoring system was used to rate BLS severity, where: 0 = no symptoms; 1 = 1%; 2 = 2 to 5%; 3 = 5 to 15%; 4 = 16% to 33%; 5 = 34 to 50%; and 6 = > 50% of leaf area affected. A disease severity index was calculated as: [( nb) / (N-1)T] x100, where n = number of leaves with a given rating, b = rating, N = number of ratings/grades in the scale and T = total number of leaves scored
