Predicting the potato leaf?

Greatgardens · August 18, 2017

I'm growing an op version of Burpee's Orange Slice, thanks to the kindness of one of our members here. I planted about 10 seeds, and only one came up with pl foliage. Naturally I planted it. It is a big indeterminate plant with very large orange fruit. The largest was 1.4#, and mostly pretty good-looking fruit that have great flavor. So this is now an F4 (IIRC), and when I save the seeds, can the percent of pl offspring be predicted? I realize that my original ten seeds was a small sample, but I would think that the results of this generation should be more like 25-50%? Or can this be successfully predicted? -GG

Once a potato leaf, always a potato leaf.

The PL leaf trait is recessive, so your PL leaf plant has two copies of that allele - and all offspring (from self-pollination) will inherit the trait.

If RL shows up among the offspring, that would be an indication of out-crossing (to explain the presence of the RL allele).
