Other claims from this paper (8)
- Observation 37% of Aphanomyces euteiches isolates had high average aggressiveness on pea near-isogenic lines.
- Observation 56% of Aphanomyces euteiches isolates had moderate average aggressiveness on pea near-isogenic lines.
- Observation 7% of Aphanomyces euteiches isolates had low average aggressiveness on pea near-isogenic lines.
- Observation Three clusters of Aphanomyces euteiches isolates were identified, unrelated to geographical origin.
- Observation The pea resistant control line was moderately to highly resistant to all tested isolates.
- Observation Five NILs carrying a major-effect resistance allele at QTL Ae-Ps7.6 had a medium to broad range of effects on the isolates.
- Observation Three NILs carrying minor-effect resistance alleles had a narrow range of effects on the isolates.
- Recommendation QTL pyramiding is needed to raise the level and broaden the range of quantitative resistance against A. euteiches in pea breeding.
