I have read lots of contradictory comments on potato leaves and their alledged qualities related to foliar disease resistence.

Last week, late blight set in here and my PL crop is SPOTLESS.

granted, they are at a f3 stage now, the PL gene has been isolated, but it could also be something else in the plant's genotype, so I just can't know....

If anyone has any hard data on this it would be highly appreciated.

My biggest hurdle in accepting this idea without peer reviewed trial data is the simple idea that a recessive gene, generally rare could NOT have taken over the general phenotype of the species if it were so superior to disease resistence - that being said, I also read that wild tomatoes are promisciously pollinated, and therefore human breeders who created all the inbred cultivars today may have had arbitrary reasons for keeping RL in so many of the popular cultivars in circulation.

Thanks in advance,

SK
