Evaluation of Tuber Yield and Marketable Quality of Newly Developed Thirty-Two Potato Varieties Grown in Three Different Ecological Zones in South Korea

Abstract

The yield and quality of potato in South Korea vary with different environmental conditions and all induced varieties do not perform well in every location. There are many suggested reasons for this problem; they include soil topography, temperature, rainfall pattern, etc. This study focused on finding certain potato genotypes based on high yield and quality (marketable rate, uniformity, less physiological disorders, resistance to diseases), and suitability for processing in three agro-ecological regions in South Korea. Thirty-two potato genotypes were cultivated in three regions i.e., Chuncheon (low altitude), Yang-gu (middle altitude), and Pyeong-chang (alpine), along with three major cultivars (Atlantic, Shepody, and Superior) as control. All the potato lines were evaluated for three consecutive years. The results showed that a higher tuber yield was obtained from the genotypes Gangwon Valley, Valley 11, Valley 13, and Valley 92 in Chuncheon; while Valley 13, Valley 43, and Valley 92 in Yang-gu; and Valley 43, Gui Valley and Valley 92 in Pyeong-chang region with a high marketable quality, and lower infection rates and physiological disorders. The results also showed that higher chip lightness was manifested by the genotypes Juice Valley, Gangwon Valley, Rose Valley, Valley 43, and Valley 91 among the high yielding genotypes. Besides, Pyeong-chang (alpine), a high-altitude region with longer maturation time was found more suitable for potato cultivation, especially for higher tuber yield and higher quality products for potato chip processing.

Farmers’ Preference, Yield, and GGE-Biplot Analysis-Based Evaluation of Four Sweet Potato (Ipomoea batatas L.) Varieties Grown in Multiple Environments

“…The difference in preference for the varieties on flesh color, taste, texture and fiber stress the importance of doing organoleptic evaluation study particularly to increase the acceptability of varieties and to disseminate the selected varieties to local preferences where possible. These scores back the results of Rahaman et al [17]; BARI Annual Report, 2014-2016 [33] and Islam et al [34].…”

Production of Potato (Solanum tuberosum L.) Seed Tuber under Artificial LED Light Irradiation in Plant Factory

“…Generally, potato seed tubers are produced at high densities in the greenhouse using different substrates and open fields. In the open field condition, potatoes’ growth and productivity depend on soil characteristics and topographic conditions [ 1 ]. Nowadays, there are multiple techniques which have been assayed to produce potato mini tubers such as hydroponic systems [ 2 ] including deep water culture systems [ 3 ], the NFT system, and the ebb and flow system [ 4 ].…”

Effect of Photoperiod and Nutritional-Shock on Increasing the Number of Minitubers from Apical Rooted Cuttings Grown in Coco-Peat

“…The potato area in the world reached 19.30 million hectares, with an average yield of 20.11 tons/ha, with an output of 388.2 million tons [2]. It consits of a high source of carbohydrates, proteins, vitamins, and minerals, so potato is currently consider a solution for feeding more than a billion people [3]. Therefore, enhancing the productivity of this root crop may be a key tool in fulfilling the nutritional requirement and the demand of minitubers for production practices.…”
