Second potato reveal from the 2018 TPS seedling plot. This reveal shows seedlings from three different lots of TPS ( true potato seed). The first three seedlings were from a cross between Igorota and Tollocan. Igorota is a late blight resistant white potato developed by the CIP (International Potato Center in Lima, Peru) and is very popular in the Philippines, over 70% of the potato crop there has been Igorota. Tollocan is another blight resistant yellow/white potato that was developed by the Mexican National Potato Program. So this cross is likely to produce mostly white tubers that at least potentially have good blight resistance from both parent varieties. We did not have any blight this season so I can't speak to the blight resistance of these seedlings.
The next group of seedlings shown are from Sarpo Duro crossed with bulk pollen. This seed was produced by my friend Nathan, and I believe he used the same bulk pollen that he used to make the Sarpo crosses in Potato Reveal #1. Sarpo Duro is a variety bred by Tom Wagner and is a descendant of either Sarpo Mira or Sarpo Axona. So while its name is "Sarpo" it is not a potato developed by the Sarvari Trust in the UK.
Finally, we harvested one plant of Muruta TPS. Muruta is another potato developed by the CIP, and it is a popular potato in Burundi in Africa for its high yield potential. It is supposed to be somewhat late blight tolerant and resistant to bacterial wilt and tropical diseases, but highly susceptible to Potato Virus Y.
