Other claims from this paper (10)
- Association Head bug numbers rose with panicle size in susceptible cultivars CSH 1 and CSH 5.
- Association Grain damage declined with increasing panicle size in CSH 1 and CSH 5.
- Association Changes in bug numbers with panicle size were not significant in resistant genotypes IS 17610 and IS 17645.
- Association Head bug numbers increased with infestation level in CSH 1 and CSH 5.
- Association The increase in head bug numbers with infestation level was not substantial in IS 17610 and IS 17645.
- Observation Grain damage was significantly lower in IS 17610 and IS 17645 than in CSH 1 and CSH 5 across infestation levels.
- Association Head bug population increased faster during rainy than dry season.
- Association Panicle size and infestation level accounted for more variation in grain damage in rainy than dry season.
- Association Panicle size and infestation level accounted for more variation in percentage grain mass loss in rainy than dry season.
- Recommendation The authors recommend testing insect resistance across panicle sizes, infestation levels and seasons.
