Performance of clonal strains of triumph potatoes

Conclusion

Even though differences in strains vary a great deal from year to year, there seem to be a few important consistent differences.

Under the conditions at Alliance with dry land culture, yields have been greatest with the later strains in all years except the very dry or drought years. Early types have produced the smoothest best type tubers that generally cracked slightly less at harvest time. Early strains almost always yielded more No. 2 size tubers, but the late strains generally produced the greatest number No. 3 size tubers.

Apparently the earliest and latest are not the most desirable strains. The midseason strains seemed the most suitable for tuber production under the range of conditions that occurred. During the ten years of these tests climatic conditions varied from one extreme to another as much as they have varied during the last 50 years.
