"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.

'복하'품종은 농촌진흥청 국립식량과학원 고령지농업연구소에서 2016년도 육성한 사계성 딸기 신품종이다. '복하'는 '고하' 품종을 모본으로 하고 '새봉3호' 품종을 부본으로 2011년 교배하여, 고온장일조건에서 당도가 높고 꽃대가 연속적으로 출현되는 우수한 사계성 개체를 선발한 것이다. 대관령의 여름재배 작형에서 2014년 생산력 검정, 2015년 특성검정을 거쳐 '새봉 8호'로 계통명을 부여하고, 2016년에 지역적응성 시험을 거쳐 '복하'로 명명하였다. '복하'의 초형은 반개장형이며, 엽형은 타원형이며, 초세가 강하다. 과실모양은 원추형이며, 과색은 연한 붉은색이다. 엽수는 32.7매로 '고하'의 22.8매 보다 9.9매 더 많다. '복하'의 당도는 9.2%로 '고하'의 9.0% 보다 0.2% 더 높다. '복하'의 평균과중은 9.5 g으로 사계성 품종 중에서 큰 크기에 속하는 편이고, 상품수량은 $27,701kg{\cdot}ha^{-1}$으로 '고하' 품종보다 72% 더 많았다. 신품종 사계성 딸기 '복하'는 수량 및 품질이 좋아 열대 및 아열대지역의 고원지대에서 재배가 가능한 사계성 딸기 품종이다.

'열하' 품종은 농촌진흥청 국립식량과학원 고령지농업연구센터에서 2013년도 육성한 사계성 딸기 신품종이다. '열하(Yeolha)'는 '고하(Goha)' 품종을 모본으로 하고 '엘시뇨(Elsinyo)' 품종을 부본으로 2008년 교배하여, 고온장일조건에서 과실이 크고, 화방이 연속적으로 출현되는 우수한 사계성 개체를 선발한 것이다. 고랭지의 여름재배 작형에서 2010-2013년 생산력 검정, 특성검정을 거쳐 '새봉 5호'로 계통명을 부여하고, 2012년에는 2지역 적응성시험을 거쳐 '열하'로 명명하였다. '열하'의 초형은 반개장형이며, 엽형은 타원형이며, 초세가 강한 편이다. 과실모양은 원추형이며, 과색은 붉은 색이다. '열하'의 당도는 8.6%로 '플라멩고'의 8.0%보다 0.6% 더 높다. 그러나 경도는 '플라멩고'보다 낮았다. '열하'의 평균과중은 12.1g으로 사계성 품종 중에서 중간크기에 속하는 편이고, 상품수량은 $28,133kg{\cdot}ha^{-1}$으로 '플라멩고' 품종보다 117% 더 많았다. 병해저항성은 시듦병에 저항성이다. '열하'는 고온장일조건에서도 화방이 연속으로 출뢰하여 다수확용으로 적당한 사계성딸기 품종이다.

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.
