Table 2 Infection types and scoring of powdery mildew disease incidence.
From: In vivo and in vitro validation of powdery mildew resistance in garden pea genotypes
Infection type | Reaction | Description |
|---|---|---|
0 | Highly resistant (HR) | No mycelium growth |
1 | Resistant (R) | Sparse mycelium growth with very little sporulation |
2 | Moderately resistant (MR) | Slight growth of mycelium is evident macroscopically. Microscopically slight to moderate growth of mycelium with conidiophores of the fungus |
3 | Moderately susceptible (MS) | Moderate growth of mycelium is evident macroscopically. Microscopically moderate development of mycelium with moderate to heavy sporulation is seen |
4 | Susceptible | Abundant growth of mycelium is evident macroscopically. Microscopically abundant development of mycelium with heavy to very heavy sporulation is visible |
