최근 전세계적으로 건강기능식품에 대한 사람들의 관심이 증가함에 따라 식용곤충에 대한 활발한 연구가 진행되고 있다. 국내에서도 식용곤충에 대한 활발한 연구가 진행되고 있으며, 그 중 흰점박이꽃무지는 동의보감에서 효능을 인정받아 식량자원으로써 연구되고 있다. 이에 근거하여 본 연구에서는 흰점박이꽃무지 성충의 먹이에 대한 선호도 조사와 사육키트 설계를 통해 생산성 증대를 꾀하고자 하였다. 흰점박이꽃무지 성충에 대한 먹이 선호도 조사는 단백질의 함량과 당도, 그리고 알부민의 함량을 달리하며 실험을 수행하였다. 단백질 함량의 실험의 경우 0 %, 1 %, 5 %, 10 %에 대한 연구를 진행하여 이 실험을 통해 단백질의 함량은 흰점박이 꽃무지의 먹이 선호도에 영향을 미치지 않는다는 것을 알 수 있었다. 당도의 경우 과일의 당도범위를 기준으로 하여 15 brix, 20 brix, 25 brix, 30 brix에 대한 실험을 진행한 결과, 20 brix가 흰점박이꽃무지가 가장 선호한다는 결론을 얻을 수 있었다. 또한 계란 흰자의 주요 단백질 성분인 알부민의 경우 0 %, 10 %, 15 %, 20 %에 대한 실험을 진행하여 알부민의 함량이 적을수록 선호도가 더 높다는 것을 알 수 있었다. 먹이에 대한 선호도조사를 사육키트 설계에 반영하여 흰점박이꽃무지 성충의 사육키트는 실제 사육장의 인터뷰를 참고하여 온도 28 °C와 습도 40%로 자동으로 조절되도록 설계하였다. 사육키트의 온도는 사육키트의 바닥에 부착된 전기 매트를 통해 조절하고 습도는 사육키트의 측면에 위치한 팬을 통해 조절된다. 또한 먹이를 간편하게 제공할 수 있도록 먹이배급장치를 별도로 설계하였다. 본 연구의 의의는 흰점박이꽃무지의 성충에 대한 먹이 선호도 조사와 사육키트의 설계를 통해 미래 식량자원으로 이용될 수 있는 흰점박이꽃무지의 생산성에 대한 연구를 제안한다는 점에 있다.

This study was conducted to evaluate the the efficacy of mulberry cake mixed diet on larval growth of Protaetia brevitarsis. As a result of adding 3, 5, and 10% mulberry cake to the fermented mulberry sawdust, the development period of the Protaetia brevitarsis larvae was 44.9days, 44.6days, and 41.8days, and the highest weight of larvae was 2.76g, 2.80g, and 2.89g, respectively. As a result of adding 3, 5, and 10% mulberry cake to the fermented oak sawdust, the development period of the Protaetia brevitarsis larvae was 46.7days, 41.6days, and 41.7days, and the highest weight of larvae was 2.65g, 2.65g, and 2.56g, respectively.

Near-isogenic lines (NILs) carrying bacterial blight resistance genes (Xa4, xa5 and Xa21) were developed in japonica rice using Suweon345 as genetic background. NILs were selected by gene specific DNA markers and inoculation of K1 or K3a race. NILs conferring Xa4 were resistant to K1, K2, K3, and moderately resistant to K3a. NILs conferring xa5 were resistant to K1, K2, K3, and K3a. NILs having Xa21 were susceptible to K1, while resistant to K2, K3 and K3a. Target genes of NILs with the genetic background of Suweon345 were also confirmed by using eleven Philippines races and International Rice Bacterial Blight (IRBB) NILs carrying Xa4, xa5 and Xa21. All NILs had no significant difference from their recurrent parents in the major agronomic traits except for panicle length and brown rice 1,000 grain weight. Heading date of NILs ranged from Aug. 10 to Aug. 11, which was similar to that of recurrent parent, Suweon345. Culm length, number of grains per panicle and ratio of ripened grain of NILs were similar to those of Suweon345. Milled rice of NILs was ranged from 4.82 to 4.93MT/ha. These NILs will be useful for improving resistance to K3a race of bacterial blight pathogens in Korean japonica cultivars.

Hopyeongbyeo is an anther culture derived Japonica rice (Oriza sativa L.) cultivar from the cross between Hitomebore and Hwajinbyeo by the rice breeding team of Honam Agricultural Research Institute (HARI), NICS, RDA, in 2003. This cultivar has a about 126 days growth duration from transplanting to harvesting. The short and round grain shape of Hopyeongbyeo is translucent with non-glutinous endosperm. Amylose content of rice grain is about 17.8% and high palatability of cooked rice compared with Nampyeongbyeo. This cultivar shows resistant to bacterial blight pathogenes of K1. The milled rice yield of Hopyeongbyeo is about 5.13MT/ha at ordinary transplanting culture in the local adaptability test. Hopyeongbyeo would be adaptable for the southern plain area of Korea.

A reaction of 214 lines and varieties to BB korean race K1, resistance and moderately resistance was 33 varieties which were bred before in 1990, susceptible were 5 varieties (Milyang23, Dongjinbyeo, Sinseonchalbyeo, Changseongbyeo and Cheongmyeongbyeo). Among bred after in 1990 resistance appeared 58 varieties, 18 varieties were susceptible. Bred after in 2000 were 50 varieties appeared resistance and 5 varieties were susceptible (Manho, Goun, Jinbong, Josaengheugchal, and Manna). Accordingly most varieties bred in south korea seemed to possession resistance to BB korean race K1. As a result of whether or not having Xa1 gene of rice varieties by SNP marker appeared that 43 varieties and the other 10 lines and varieties have Xa1 gene. Varieties bred before in 1990 have 18 (62.1%) varieties out of 29 varieties possession Xa1 gene to showed resistance to BB korean race K1, 19 (47.5%) varieties bred in 1990~2000, 6 (12.8%) varieties (Boseogchal, Daepyong, Hanareumbyeo, Hopyeongbyeo, Jongnam, Kuman) bred after in 2000 seemed to possession Xa1 gene.
