Screening Introduced Potato Varieties for Yield, Stability and storability under the Arid Conditions of Sudan

Abstract

A research program was carried out to evaluate eight potato varieties during two seasons during 2017-2019 for yield, stability and storability at three locations (Khartoum, Shendi and Dongola). Potato varieties Alaska, Colombia, Evora, Fortus, Panamera, Challenger, Sagita and Markies, were received from Netherlands by the National Varieties Release Committee (NVRC), Sudan. Experiments were arranged in a randomized complete block design and a completely randomized design for storage parameters. Sagita produced the highest marketable yield in all sites. Moreover, it had the heaviest tuber weight and showed stable performance. However, Challenger had the highest dry matter content (22.5%) and Alaska showed the lowest dry matter content (16.6%). Varieties Sagita, Fortus and Chalenger showed the least weight loss percentage during six months storage period at 4ºC, while Colombia had the highest weight loss percentage.
