“…From the pooled value of two consecutive years, it was found that CIP 394600.52 produced the highest yield (31.225 mt/ha) followed by CIP 395443. Seed sized tuber yield determines the economic value of tuber production (Kim et al, 2017). In the present experiment, seed sized tuber rate varied with respect to genotypes.…”

A series of experiments were carried out to evaluate the performance of exotic potato clones including PRP lines at research field of Regional Agricultural Research Station (RARS), Parwanipur, Bara, Nepal during the winter seasons of 2017 and 2018. Thirty-nine potato clones were evaluated in initial evaluation trial and eleven clones were evaluated in coordinated varietal trial with check varieties Khumal Ujjwal and Kufri Jyoti. From the initial varietal trial in 2017, the highest tuber yield (21.54 mt/ha) was found in CIP389660.9 followed by CIP391046.14 (21.38 mt/ha). In 2018, the highest tuber yield (29.72 mt/ha) was produced in CIP392759.1 followed by CIP393085.5 (26.92 mt/ha) and CIP391046.14 (26.64 mt/ha). In 2018, the tuber yield was the highest (26.12 mt/ha) in PRP 266265.15 followed by CIP 393371.159 (24.79 mt/ha). In coordinated varietal trial carried out in 2017/18, the highest tuber yield was noted in CIP394600.52 (42.65 mt/ha) followed by CIP395443.103 (30.83 mt/ha) and CIP395445.16 (24.43 mt/ha) respectively. Whereas in 2018/19, the highest yield was produced by PRP266265.15 (26.12 mt/ha) followed by CIP393371.159 (24.79 mt/ha) and CIP 396012.266 (22.66 mt/ha) respectively. In RARS, Parwanipur conditions, CIP 394600.52, CIP 395443.103, CIP 395445.16 and CIP 304394.56 along with PRP 266265.15 were found to be superior to standard check variety. These potential genotypes need to be further verified in farmers field in additional districts of central Terai region before notifying in the national seed system. Adoption of these clones as variety may increase the potato production and improve the food, and nutritional security in the central Terai region of Nepal.

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

et al. 2020

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.

“…During the early growth phase of potato, the elevated temperature has been reported to facilitate the development of the above-ground portion of the plant [ 13 , 14 , 24 ]. However, when the air temperature deviates from the effective range, the net photosynthetic rate falls at both the leaf and canopy levels and limits the accumulation of assimilates [ 22 , 23 , 57 ]. The activity of PS II, where the photosynthetic reactions occur, has been reported to increase within the effective temperature range for potato (18–20°C) but to decrease at higher temperatures [ 17 , 23 , 24 , 58 , 59 ].…”

The effect of concurrent elevation in CO2 and temperature on the growth, photosynthesis, and yield of potato crops

et al. 2020

Global climate change accompanied by continuous increases in atmospheric carbon dioxide (CO 2) concentration and temperature affects the growth and yield of important crops. The present study investigated the effect of elevated temperature and CO 2 concentrations on the growth, yield, and photosynthesis of potato (Solanum tuberosum L. cv. Superior) crops using Korean Soil-Plant-Atmosphere-Research chambers that allow the regulation of temperature and CO 2 concentration under daylight conditions. Based on the average temperature from 1991 to 2010 in the Jeonju area, South Korea, potato plants were exposed to four different conditions: ambient weather (400 μmol mol-1 , aCaT), elevated temperature (+4˚C, aCeT), elevated CO 2 concentration (800 μmol mol-1 , eCaT), and concurrently elevated CO 2 concentration and temperature (eCeT). Under aCeT conditions, the temperature exceeded the optimal growth temperature range towards the late growth phase that decreased stomatal conductance and canopy net photosynthetic rate and subsequently reduced biomass and tuber yield. Stomatal conductance and chlorophyll concentration were lower under eCaT conditions than under aCaT conditions, whereas late-growth phase biomass and tuber yield were greater. Compared to other conditions, eCeT yielded a distinct increase in growth and development and canopy net photosynthetic rate during tuber initiation and bulking. Consequently, biomass and canopy net photosynthesis increased, and tuber yield increased by 20.3%, which could be attributed to the increased tuber size, rather than increased tuber number. Elevated CO 2 reduced chlorophyll, magnesium, and phosphorus concentrations; reducing nitrogen concentration (by approximately 39.7%) increased the C: N ratio. The data indicate that future climate conditions will likely change nutrient concentration and quality of crops. The present study shows that while elevated temperature may negatively influence the growth and yield of potato crops, especially towards the late-growth phase, the concurrent and appropriate elevation of CO 2 and temperature could promote balanced development of source and sink organs and positively effect potato productivity and quality.
