Potato cultivars or selections included in this report were selected from recently released cultivars, advancing selections with release potential (numbered lines progressing through the trial process), or cultivars that are new to the U.S. Standard potato cultivars used by growers served as checks. The agronomic data presented in Tables 1 and 2 were analyzed statistically. These analyses allow the reader to ascertain, at a predetermined level of confidence, if the differences observed among cultivars/selections are reliable, or if they might be due to error inherent in the experimental process.

At times, potato growers may experience poor emergence of potato plants. There are number of reasons why potato plants may not emerge properly. This article is intended to provide a list of common problems that can cause poor potato emergence and stand. Utilizing this list can help growers more rapidly identify the cause and improve management of the crop and subsequent crops.

Potato cultivars or selections included in this report were selected from recently released cultivars or from advancing selections or cultivars that are new to the United States. In 2019, two trials were conducted to identify traits of red-skinned and yellow-skinned potato cultivars and advanced selections at Hoople, N.D.

The term secondary growth is often described as heat sprouts, tuber chaining and tuber malformations. This physiological disorder decreases yield and quality of all potato tubers. Good management and varietal selection can minimize this.

From time to time there are shortages in the seed supply and some growers want to plant back non-certified seed. The objective of this article is to cover these rules for North Dakota and Minnesota and discuss how to select the best seed tubers.
