        This study compares the quality characteristics of Jeung-pyun prepared by supplementing with rice mash of various cultivars. Results showed high contents of crude protein and crude ash in Saeilmi. The highest and lowest amylose contents were obtained in Goami4 and Baekjinju, respectively. Saeilmi had the highest water absorption index (WAI) of rice flour, whereas the highest water-soluble index (WSI) was obtained in Baekokchal. Maximum viscosity, minimum viscosity, and breakdown were high in Baekjinju, and high cooling viscosity and setback levels were determined in Goami4. The sugar content, total free sugar, and pH of the rice mash were highest in Baekjinju. The highest volume of Jeung-pyun was obtained with Saeilmi supplementation, whereas the specific volume was highest in Baekokchal. Evaluation of L, a, and b color values of Jeung-pyun revealed the maximum L value in Saeilmi, a value in Goami4, and b value in Baekjinju. The physical properties of Jeung-pyun were lower in all supplemented groups compared to the control group for hardness, adhesiveness, and chewiness. The lowest chewiness was obtained in Baekokchal-supplemented Jeung-pyun. We conclude that supplementation with different varieties of rice affects the quality characteristics of Jeung-pyun, which are important factors for manufacturing processed foods.

        본 연구는 allelopathic potential을 지닌 벼의 교잡종을 포장에서 재배하여 그 식물체의 잎을 생물검정에 이용하여 allelopathy 효과 유무를 검정하고, 생물검정으로 선발된 교잡종을 대상으로 phenolic compounds를 조사하여 allelochemical로써의 가능성을 확인하고 나아가 phenolic compounds 생합성에 관여하는 효소의 활성 측정과 이 효소의 작용에 의해 유도되는 phenolic compounds를 구명한 결과는 다음과 같다. 1. 포장상태에서 피를 대상으로 생물검정을 실시한 결과 양친으로는 Kouketsumochi, Woo co chin yu에서 공통적으로 90% 이상의 높은 피뿌리 생장 억제율을 보였고, 교잡종에서는 Kouketsumochi/Woo co chin yu, Dongjinbyeo/Kouketsumochi, Dongjinbyeo/Woo co chin yu 조합에서 80% 이상의 높은 억제율을 나타냈다. 2. Kouketsumochi의 PAL 활성은 protein 1kg당 로 타 공시품종보다 높았다. 또한 Kouketsumochi와의 교잡종도 타교잡종보다 높은 것으로 나타났다. 3. Kouketsumochi의 cinnamate 함량은 생체중 1g당 으로서 다른품종이나 교잡종보다 2~5배 높았고, Kouketsumochi와의 교잡종도 타교잡종보다 높았다.

        벼멸구에 대한 벼품종의 저항성요인으로 주목되고 있는 선호성, 란 및 약충기간, 부화 및 우화률, 성비, 성충의 수명 및 산란력 등을 조사하였다. 식이 및 산란선호성은 동률벼에서 생태형 모두 높은 선호성을 보였으며, 청청벼와 밀양63호에서는 각각 생태형-2와 3에서 약간 높은 선호성을 보였으나, 동률벼에 비해서는 현저히 낮은 선호성이었다. 난 및 약충기간과 부화율, 우화률 및 생장 지수는 생태형-1의 경 우 타 품종에 比해 密陽 23號에 서 짧고, 높았으며 , 또態型-2와 3 은 各各 좁 팍벼 와 密陽 63號에 서 密陽 23號에서와 같이 짧고, 높게 나타났다. 성충의 수명과 산란수도 생태형-1의 경우 타 품종에 비해 밀양 23호에서 길고, 많았으며, 생태형-2와 3은 각각 청청벼와 밀양 6 63호에서 밀양 23호에서와 같이 수명이 길고 산란수도 많았다.

        The organic acids, fuel oil contents and antioxidant activities of Yakju with the addition of rice varieties were investigated. The rice cultivars that were used in this study were Ilmi rice, Hopyung rice, Hopum rice, Hanarum rice, Anda rice and Indica rice. The study results are as follows: the pH values of Ilmi Yakju and Hanarum Yakju were 4.14 and 4.07, respectively, and those of the other Yakjus, 3.92~3.98. The total titratable acid content of the Yakju for which Indica rice was imported from Thailand was highest among the samples. The reducing sugars content of the Yakju for which Indica rice was used was higher than that of the other samples. The ethanol content of the Hanarum Yakju was higher than that of the other Yakjus, and the lowest ethanol content was found for the Indica Yakju. The major organic acid component of the Yakju was lactic acid. The total organic acid content was highest in the Indica rice Yakju. The amounts of the following main fusel oils were highest, in the following order: 2-butyl alcohol, 2-pentanol, N-propyl alcohol, acetaldehyde, ethyl acetate, methyl alcohol and 2-methyl-1-propyl alcohol. The DPPH free radical scavenging activity of the Indica rice Yakju was much higher than that of the Ilmi rice Yakju and the Hanarum rice Yakju. Also, the SOD activity of the Indica rice Yakju was strongest among all the samples. The total polyphenol content of the Indica rice Yakju was the highest among all the samples.
