본 연구는 중국 길림성의 인삼재배기술현황과 토양이화학성 등을 조사분석함으로써 FTA 대응 중국삼과 국제경쟁력을 확 보하고 국내인삼산업발전에 기초정보를 제공하기 위하여 수행 하였다. 1. 지역별 인삼재배 형태는 대부분 임야를 개간하여 재배되 었고 평지 재배는 미미하였다. 이식재배가 직파재배보다 많으 며 밀식재배 하였고 종자는 주로 중국재래종을 구입하여 재배 하였고 자가채종도 40% 이상을 점유하였다. 2. 지역별 해가림 시설은 일정한 설치 방향이 없었고 대부 분 아치형 형태로 설치하였으며 한국과 달리 두둑폭이 180 ~ 200cm 로 광폭재배를 하였고, 차광자재는 흑색차광망+ 청색비닐을 사용하였다. 3. 인삼재배농가의 토양이화학성을 분석한 결과, 길림성 북 부(연변자치주)와 남부지역 모두 토성은 양토 ~미사질양토였 으며 pH는 5.2 ~ 5.5범위로 강산성을 보였고 유기물 함량이 매 우 높은 토양이었다. 4. 특히, 인삼재배토양(표토)의 EC가 0.97 ~ 1.11 dS/m로 높 아 인삼생육기 염류피해가, 치환성양이온 중 Ca함량이 8.4 ~ 12.3 cmol+/kg로 높아 양분불균형 피해가 우려되었다.

“Ilyeop” (Perilla frutescens (L.) Britton), a new cultivar for leaf vegetable, was developed from a cross between Ipdeulkkae1 and YCPL187 at the National Yeongnam Agricultural Experiment Station, RDA, in 2001. For the cultivation of leaf vegetable perilla, the plants are grown with a spacing of 10 × 5 cm between rows and plants and all branches are removed to harvest uniform leaves from main stem, indicating that the amount of the next harvesting leaf is a important characteristic for the growth of the plant. “Ilyeop” grows vigorously and yields high quality leaf with higher amount of the next harvesting leaves composed with a check cultivar, “Ipdeulkkae1”. “Ilyeop” has five days of earlier seed maturity (Oct. 24) than that of “Ipdeulkkae1” under natural condition, less chance of frost damage is expected. The flowering date of “Ilyeop” is same with that of “Ipdeulkkae1” in winter cultivation with night break treatment.

“Bora” is a new perilla (Perilla frutescens (L.) Britton) cultivar developed from a cross between Ipdeulkkae1 and YCPL199 at National Yeongnam Agricultural Experiment Station, RDA, in 2001. Purple backside leaf color is one of the most important characteristics for the high quality perilla leaf. “Bora” has purple backside leaf color in all climate condition, while a check variety, Ipdeulkkae1 has too light color during summer season or in high temperature condition. “Bora” matures at October 18th and has 79 cm of the stem length, shorter than that of Ipdeulkkae1. Although leaf yield is 11% less than that of a check variety Ipdeulkkae1, the harvested leaf number of “Bora” is similar with that of Ipdeulkkae1. The cultivar is appropriable in all area of Korea for the leaf harvesting cultivation whereas it is restricted to southern part of Korea South Gyeongsang and South Jeola provinces, for the seed harvesting cultivation.

To ensure the durability of resistance to blast disease in high-quality japonica rice a long-term rice breeding project to develop a few blast-resistant multiline cultivars was carried out from 1987 to 1999. Seven resistance donors were selected based on
