  • "Doha" is a new strawberry (Fragaria x ananassa Duch.) variety, which was released by the Highland Agriculture Research Institute in 2021. The "Doha" variety originates from a 2014 cross between "Saebong No. 3" and "Yeolha," both of which exhibited excellent ever-bearing characteristics, including continuous flowering and large fruits under long-day and high temperature conditions. This new cultivar was initially named "Saebong No. 13" after examining its characteristics and productivity during summer cultivation between 2015 and 2018. After regional adaptability tests, "Doha" was selected from "Saebong No. 13" as an elite cultivar. The general characteristics of "Doha" include spreading, elliptic leaves, and strong growth. The fruits are long and conical and of a red color. The plant height of "Doha" was similar to that of "Goha," but the number of leaves was lower. The number of flower clusters of "Doha" was 8.6, which was 2.8 fewer than that of the control variety, "Goha," with 11.4. The average fruit weight of "Doha" was 13.9 g, which was 4.9 g heavier than that of "Goha." The fruit hardness of "Doha" was 35.5 g·mm-2, which was 9.4 g·mm-2 harder than that of "Goha." The marketable yield of "Doha" was 26,971 kg·ha-1, 125% more than that of "Goha" with 21,479 kg·ha-1. The findings of this study suggest that "Doha" is a hard fruit and high-yielding variety of ever-bearing strawberries that could increase farming income when distributing to farmers.

  • 'Bokha' is a new strawberry (Fragaria x ananassa Duch.) cultivar, which was released by the Highland Agriculture Research Institute in 2016. The 'Bokha' cultivar originated from a cross between 'Goha' and 'Saebong No. 3' that showed excellent ever-bearing characteristics, including continuous flowering habit and high soluble-solids contents under long-day and high temperature conditions in 2011. This cultivar was initially named 'Saebong No. 8' after examining its characteristics and productivity in summer culture from 2013 to 2015. After regional adaptability tests in 2016, 'Bokha' was selected from Saebong No. 8 as an elite cultivar. The general characteristics of 'Bokha' include semispreading type, elliptical leaves, and moderately vigorous growth. The fruits are conical in shape, and red in color. 'Bokha' plants have 32.7 leaves, 9.9 more than 'Goha' plants. The soluble-solids content of 'Bokha' was 9.2%, which was 0.2% higher than that of 'Goha'. The average fruit weight of 'Bokha' was about 9.5g and the marketable yield was $27,701kg{\cdot}ha^{-1}$, 72% higher than 'Goha'. 'Bokha' is suitable for tropical and subtropical zone cultivation as a high soluble solids contents cultivar, because it shows continuous flowering habit under long-day and high temperature conditions.

  • This work characterizes 'Yeolha', a new strawberry (Fragaria ${\times}$ ananassa Duch.) cultivar that was released by the Highland Agriculture Research Center, RDA, in 2013. This cultivar originated from a 2008 cross between 'Goha' and 'Elsinyo' and showed excellent ever-bearing characteristics including continuous a flowering habit under long-day and high temperature conditions. It was originally named 'Saebong No. 5' after examining its characteristics and productivity in summer culture from 2010 to 2013. After two regional adaptability tests in 2012, it was selected as an elite cultivar and renamed 'Yeolha'. The general characteristics of 'Yeolha' include a semi-spreading plant type, elliptic leaves, and strong vigor in growth. Its fruit is conical and red. T he s oluble s olids content of 'Yeolha' is 8 .6%, w hich is 0.6% h ig her than t hat of 'Flamenco', b ut f ruit hardness is lower than that of 'Flamenco'. The average fruit weight of 'Yeolha' is about 12.1 g and the marketable yield is $28,133kg{\cdot}ha^{-1}$, which is 117% higher than that of 'Flamenco'. 'Yeolha' is resistant against Fusarium wilt. In addition, 'Yeolha' is suitable for four-season cultivation as a high harvesting cultivar because it shows continuous flowering under long-day and high temperature conditions.

  • As the demand for processing potatoes increases, imports of raw potatoes and potato products are increasing, so it is necessary to expand potato production as raw materials for processing in Korea. Potato varieties for processing that can be grown in fall have been developed, but research on cultivation technology and processing quality management technology to improve chip processing quality is very insufficient. Therefore, this study was conducted to investigate the optimal harvest time by investigating the quantity and chipping characteristics of potato chips during autumn cultivation. As the test varieties, the chip processing varieties "Saebong", "Eunsun", and "Geumnaru" were used, and the potato cultivation site was the Seocheon-gun Test field (214 Gaeya-ri) of the Chungcheongnam-do. The test treatment was at harvest time after spring cultivation, and the potatoes were harvested at 70, 80, 90, and 100 days after sowing based on the sowing time. The investigation items were potato productivity (total yield, yield of standard processing, and number of tubers) and chip-processing characteristics (chip color, dry matter content, glucose content, etc.). As a result of examining the yield characteristics according to the harvest time, statistical significance was not found according to the treatment. The total yield (ton/ha) was 27.5 to 30.5, and there was no significant difference depending on the time of 70 to 100 days after harvest. The standard quantity for processing (yield of 81-250g potatoes per unit) also showed a similar trend. In chipping characteristics according to harvest time, statistical significance was high in specific gravity and glucose content. The specific gravity was highest at 1.077 at 70 days after harvest, and the glucose (mg/dL) content was the lowest at 37.5 at 80 days after harvest. Statistical significance was not recognized, but chip color (L value) was the highest at 64.4 at 70 days after harvest. Therefore, it is judged that the optimal harvesting time for chip processing is 70 to 80 days after sowing.
