Some runner-up F2s

These are not homozygous for gf.  But they have a 2/3 chance of being heterozygous; if so 1/4 of F3s will be gf/gf.   Otherwise they are big, or at least medium-big, and have good purpling - worth a try at the F3 stage.  In addition to these, note #s 20 and 49 which produced at least 1 rather large fruit, approaching 1 lb; and #28 which was a prolific cherry!
