COMPARISON OF FINAL 131 WITH COMMERCIAL CULTIVARS AND PARENTAL PLANTS

(6) Final 131 is similar to its male parent, Sweetheart, in that both have S-alleles S3S4, are self-fertile and have a medium strong tree habit. Final 131 is distinct from Sweetheart by its longer stem length, larger fruit size, and a fruit ripening time that is ten days later. In addition, the fruit color of Final 131 is black-red compared to the more brown black color of the fruit of Sweetheart.

(7) Final 131 is distinct from the Prunus cultivar Tieton (U.S. Pat. No. 11,385), by its S-alleles, which are S3S9 compared to S-alleles S3S4 in Final 131. Final 131 is 20 days later in fruit ripening than Regina (not patented). The fruit shape of Final 131 is heart-shaped compared to Regina, which has a more round-shaped fruit. Final 131 has firmer fruits than Regina. Flowering in Final 131 is medium-early in flowering compared to Regina, which is very late.
