My goal this year (2nd year growing potato onions), was to produce seeds from those that were started in 2020. In 2020, I spring planted about 24-25 surviving seedlings that were harvested in August. Then fall planted in October, 2020 at the same time I plant my garlic. About 1/3 of them did not emerge in 2021.
About 6 of them flowered and after cutting the flower stalks/stems and leaving in a glass of water for a few weeks, was able to dry the flower heads and collect seeds.
Yields of the 2020 plants were low, but it gives me seeds to start with in 2022.
I also planted about 15 more seedlings in 2021 and will use these and the 2020 bulbs in 2022 to try to produce better yields. I am thinking of planting about half in the fall and half in the spring to compare how they do.
Segregation from both batches has been ~50% with varying degrees of red or pink, and ~45% yellows. There was 1 white bulb (~2%)
My original seeds were from the Cultivariable Participatory Breeding Project (OSSI pledged), so they are not directly from EFN, but I believe EFN was probably a contributing source.
I am in Rhode Island (USA), on the edge of zone 6b/7a.
