COMPARISON WITH PARENTAL AND SIMILAR COMMERCIAL VARIETIES

(10) The female parent plant of SWTCOL, cultivar NF 101 (unpatented), is no longer in existence, so a meaningful comparison cannot be made.

(11) The male parent plant of SWTCOL, cultivar NF 302 (unpatented), is no longer in existence, so a meaningful comparison cannot be made.

(12) When SWTCOL is compared to the commercial variety Maxim (U.S. Plant Pat. No. 5,782), SWTCOL has conical shaped fruit, whereas Maxim has round fruit.

(13) When SWTCOL is compared to the commercial variety Alba (unpatented), SWTCOL has a mid-season harvest maturity, whereas Alba has an early harvest maturity.

(14) When SWTCOL is compared to the commercial variety Sweetheart (unpatented), SWTCOL has very large fruit, whereas Sweetheart has medium sized fruit.
