My point is that with Immortality X cyclic rebloomer, Immortality does not add any potential to rebloom that can't be gotten with any vigourous strong growing plant. Even oncers.  Plants with much better characteristics, giving a much higher proportion of quality seedlings.  And just as high a percentage of cyclic rebloomers. More product with less work.

This is because cyclic rebloom genes are dominant. The summer rebloom genes in Immortality are recessive, and will only produce a summer rebloomer if matched with other summer rebloomers. The rebloom factor in Immortality is irrelevant in a cross with a cyclic rebloomers

1)  Cyclic Rebloomers X vigorous plants = cyclic rebloomers
2) Summer rebloomers X vigorous plants =  all oncers (unless they are carriers of summer rebloom genes)
3) Cyclic rebloomers X Summer rebloomers =  cyclic rebloomes (same proportion as #1)
4) Immortality X Cyclic rebloomers = cyclic rebloomers (same as #1 & #3)  but with a small proportion of quality plants.
