RESUIS OF POTATO VARIEfT AND SEEDLMNG TRIAL 1965

E. N. McCubbin

Sixteen potato varieties and 8 seedlings were grown in a yield trial at
Hastings in 1965. Seed were obtained mostly from the USDA Potato Breeding Program
at Presque Isle, Maine and Baton Rouge, Louisiana. A seedling is a potentit
potato variety that has never been named. After it is grown and proved acceptable,
a name may be assigned to it.

The variety trial was located on Rutledge fine sand which had been cleared
within the last 5 to 7 years. The plots were fertilized uniformly with 2,663
pounds 6-8-8 por acre and given the same treatment throughout the potato growing
season.

Results: White varieties which yielded significantly less than Sebago, the
standard variety at Hastings, were Haig, Pemn Chip, and seedlings, B4860-5, and
X792-94. Russet seedling ND4192-3 also yielded significantly less than Sebago.
White varieties yielding more than Sebago but not significantly were LaChipper,
Huron, Eaaet, FUndy and Avon. Red seedlings which did not significantly outyield
Sebago were TL8197 and TL8134. Norland, a red variety also yielded more than
Sebago, but this was not significant. The standard Sebago variety was significantly
outyielded in good US1A by four white varieties, Allahanna, Ona, Snawflake, and
Pungo, and seedling B 2894-24. Red varieties TaRouge and Catoosa also yielded
significantly more than Sebago. No red seedlings significantly outyielded Sebago.

In the results of this trial, Sebago produced smoothest, most marketable
potatoes. It is also noted for its chip making qualties. It is doubtful that any
other white potato variety should be grown in place of Sebago in this area at
this time. If one should like to grow another white variety the following may be
tried on a small scale. They are Ona, LaChipper, and Fundy. Pungo is resistant to
Corky Ringspot, and it should be used on soil infested with this virus disease.

Best red varieties for this area when needed are Red LaSoda, Pontiae, and
Catoosa. LaRouge produced the top yield in the trial last year and may also be
tried on a small scale.
