Background : The most problematic disease in Boxthorn is Anthracnose in open field. New variety with Anthracnose-resistant is good for high yield and Safe fruit production in open field. Therefore it is necessary to develop a new variety with Anthracnose -resistant and high yield. Methods and Results : The new boxthorn line, CB10511-104 was selected from the cross between CB09480-18 and Chunghong (IT258916) to breed new variety with high yield, Anthracnose-resistant and good color in 2011. Its preliminary yield test was performed from 2013 to 2014 and the selected line was named Cheongyang 26. Its regional yield trials were carried out in Cheongyang, Yesan and Jindo for 3 years, from 2015 to 2017. Cheongyang 26 was registered as the new variety, Cheonggang, in 2017. The specific characteristics were summarized as follows. Tree shape is semi-open type and the leaf is lanceolate and green color. The flowers are normal size and purple. The fruit is normal size, round oval and redish. The flowering was June 17 with medium flowering. Number of sprout branch by pruning was generated less than the check variety, Cheongmeong. The infection rates on leaves to Eriophys macrodonis Keifer of Chunggang, 54.4 percent, was higher than the check variety, Cheongmeong. Anthracnose on fruits in open field was slightly strong compared to the check variety, but check variety was Anthracnose-resistant. The content of betaine and free sugar in dried-fruits were higher than that of the check variety. The dried-fruit yield was increased about 26 percent in open field compared Cheongmeong. Conclusion : This variety ‘Cheonggang’ was suitable for cultivation in open field and rain-shelter plastic greenhouse because of Anthracnose-resistant and good color. It is necessary the companion variety because of self-incompatible. It’s suitable ‘Cheonggeum’ in open field, ‘Cheongun’ in rain-shelter plastic greenhouse.

파라핀 왁스를 산화시키고 최적의 반응조건을 찾기 위해 교반기, impeller,공기diffuser, temperature controller, silicon oil bath, silicagel dry trap 등으로 구성된 반응장치를 제작하였다. 촉매인 KMnO₄의 suspension을 형성하고 diffuser를 하향으로 하며 Rushton turbine impeller로 교반함으로써 미세한 공기방울을 형성하는 등 반응 조건을 개선하였다. 촉매의 양 및 성상 조절, 기액접촉 방법의 개선 그리고 반응기의 형태 변형 등을 통해 산화반응물의 비누화가 및 산가를 향상시킬 수 있었다. 반응물 GC/MS분석을 통해서 포화탄화수소의 일부가 지방산으로 분해되었음을 확인할 수 있었다. 이러한 노력에 의해 생성물의 비누화가 193, 산가 85를 주는 산화반응의 최적조건을 얻을 수 있었으며 100ℓpilot 반응기를 이용하여 그 상업적 생산 가능성을 확인하였다. In order to oxidize paraffin wax and to find out optimal reaction condition, reaction apparatus was set up with agitator, impeller, air diffuser, temperature controller, oil bath and silica gel dry trap etc. The catalyst, potassium permanganate, was added in the form of a concentrated aqueous solution, the diffuser head was toward the bottom of the reactor and Rushton turbine type impeller was selected. The saponification number and acid value of oxidation product increased by controling the amount and the state of catalyst, improving gas-liquid contact, and changing the set up of reactor. The analysis of reactants and products by FTIR and GC/MS confirmed the formation of fatty acid. As a result, saponification number of 193 and acid value of 85 were obtained at the optimum condition. Finally, the possibility of its commercial scale-up of the process was found from the experiment in 100ℓpilot reactor.
