Table II.
Rice Material | Disease Indexa | Resistance/Susceptibility |
CO39 (susceptible control) | 75.6 | Highly susceptible |
Mudanjiang 8 (wild type) | 40.0 | Moderately susceptible |
D176UM11 | 14.4 | Resistant |
D176UM34 | 13.3 | Resistant |
Disease index was calculated with the individual leaf ratings using the following formula: disease index = [sum of numerical ratings from all leaves/(number of leaves assessed × maximum lesion rating)] × 100. Data were from 38 and 37 plants in lines D176UM11 and D176UM34, respectively.
