Hello Ahmad,
For the other 2 breeders I don’t have experience, I bet to PSB to my nectarines collection because in the last years PSB have released really strong varieties with higher rated taste, other breeders are doing well too( taste+resistance) like ASF but unfortunately get ASF varieties is more difficult (at least for me).
I have seen that where you are living , I understand that you suffer from high humidity in the summer, so we are in similar situations and therefore we need more or less the same, it would be also important to know what type of spray management you do in your orchard, this information could make you discard or not discard some varieties,
I do not fumigate to force the selection of what can withstand and to see/check what is the behavior of each variety or I only spray one time in Winter some years , not all years and sometimes not all trees, just I test and see the results…take in consideration in Summer I have more than 80% humidity, it,s too much cloudy, rainy….
So I look for the more resistant trees that can survive and produce with a minimum cares.
So, with that premises, the stronger PSB varieties with very good or excellent taste are Atanais, Tifany, Kinolea and Esmeralda.
That means no cracking, no split pits, no important/high fungal damages, therefore long post-harvest period, no fruit losses for monilia….
For example Atanais is in the same level of PLC resistance as the most old famous varieties to be PLC resistance.
Kinolea and Esmeralda are a bit more resistance in terms of monilia, brown rot …but a bit less regarding PLC
If you spray, open the door to the ones are susceptible to PLC in a medium level damage or let’s say a normal level of most of modern nectarine varieties, for instance Clariss is supposed to be excellent taste( I didn’t eat yet) my tree is young yet, hope to do it this year.
or even Boreal is in the same PLC level than Clariss and taste is rated as excellent, my daughters and wife love it, also there is a big difference if they have 2Brix more, it change from very good to excellent.
I didn’t added in my collection the older PSB varieties, just I added the newest varieties.
Keep in mind in the last few years in commercial productions PSB is the one with higher increase of planted Hectáreas , so this is the fact, looks some PSB nectarine varieties have win a relevant place in commercial level and also valid for our home orchards.
Best Regards
