Evaluation of New Canal Point Sugarcane Clones
1997-98 Harvest Season

Summary

The four most promising clones in the CP 93 plant-cane experiments were CP 93-1596, CP 93-1309, CP 93-1634, and CP 93-1382. CP 93-1596 and CP 93-1634 had high TC/H yields and moderately low KS/T yields. CP 93-1309 had moderate TC/H yields with very high KS/T yields. CP 93-1382 had moderately high TC/H yields, low preharvest KS/T yields, and high but unstable harvest KS/T yields.

This year, the CP 92 series was tested at three locations in the plant-cane crop and at seven locations in the first-ratoon crop. CP 92-1666, CP 92-1167, and CP 92-1435 had high overall TS/H yields when combining this year's plant-cane and first-ratoon results with last year's plant-cane results from seven locations. CP 92-1641 had a high mean TS/H yield across the three plant-cane tests this year and across the seven plant-cane tests last year. CP 92-1641 had moderately high TS/H yields this year in the first-ratoon tests; its main attribute was high mean KS/T yields in all tests.

This year, the CP 91 series was tested at three locations in the first-ratoon crop and at seven locations in the second-ratoon crop. CP 91-1914 had the highest mean TS/H yield overall, but its TS/H yields in the second-ratoon experiments, relative to the other clones, were higher than those in the first-ratoon experiments. CP 91-1924 had high yields on successively planted land in the first-ratoon crop; and CP 91-1883 and CP 91-1238 had high first-ratoon yields on the Torry muck soil.

Four years of testing the CP 90 series was completed this year with three second-ratoon experiments. As identified previously for this group of clones, CP 90-1549, CP 90-1222, and CP 90-1464 had high TS/H and TC/H yields. A major drawback for CP 90-1549 and CP 90-1222 has been their moderately low KS/T yields. Uncertain disease susceptibility has been the primary negative characteristic of CP 90-1464.
