Resistance code
PVY, PepMoV, TEV, pvr2-1, pvr2-2, pvr4
Affects
Pepper, Tomato

Symptoms

Vein-banding mosaic and puckered young leaves, with stunted plants and small unmarketable pods. Spread by aphids in seconds of probing, which is why insecticides rarely prevent it.

Management

Resistance genes are the practical control, and commercial pepper varieties list potyvirus resistance (PVY, TEV, PepMoV) as a package because the same recessive pvr genes often cover several. Reflective mulch delays aphid arrival; roguing infected plants early limits the within-field spread.

This is the page where the difference matters most, because it is where a variety gets chosen for its resistance. Breeder declared means the claim comes from whoever breeds or sells the seed, which for most resistance genes is the only evidence that exists. Independently observed means an institution with no stake in the sale grew the plant and reported what happened.
