Agronomics of New Red-Skinned Potato Cultivars (1999) - 4 pages

Cultivars tested;

Norland - is the standard red-skinned variety for the Canadian Prairies. It is early maturing

with excellent yields of fairly uniform tubers, but its skin tends to fade during

storage.

Cherry Red - this Colorado variety is exceptionally red and holds its color well. This variety

maybe too slow-maturing for local growing conditions.

VO498-4 - is a new release from the potato breeding program at Agriculture Canada

Lethbridge. This variety has produced excellent yields of very uniform tubers

under irrigated conditions but had performed poorly under drought stress.

This trial evaluated the impact of seed piece spacing on the yields and tuber size distribution of

these red-skinned varieties under irrigated and dryland conditions. The spacings tested were

15, 25 and 35 cm (6, 10 and 14"). The 25 cm spacing would represent the norm for Norland

under irrigation while a wider spacing would be more typical in dryland production.
