버섯의 편중재배 현상을 줄이고 경쟁력있는 품목을 육성하기 위해 재배기간이 짧고, 발이가 안정적이며, 수량이 높은 꽃송이버섯을 개발하고자 하였다. 2016년부터 국내외에서 유전자원을 수집하고 교배하여, 특성검정 및 생산력 검정, 농가실증을 통해 육성된 꽃송이버섯 신품종 '한여울'의 주요 특성은 다음과 같다. 균사생장적온은 22~25℃, 발이 및 생육온도는 19~21℃로 대조품종(너울)과 유사하였다. 재배일수는 생산력 검정(병재배)에서 125일로 대조품종 대비 39일, 농가실증(봉지재배)에서 98~102일로 대조품종 대비 9~12일 짧게 나타났다. 갓 색은 연황백색으로 대조품종과 유사하였고, 갓 끝부분의 형태는 수국형으로 갓의 굴곡 간격이 대조품종 대비 넓었다. 발이율은 생산력 검정(병재배)에서 93.7%, 농가실증(봉지재배)에서 90.2~90.9%로 대조품종 대비 안정적이었다. 수량은 생산력 검정(병재배)에서 1,100 cc(Ø75 mm)병 기준으로 79.1 g 대조품종 대비 22.6%, 농가실증(봉지재배)에서 2.6 kg봉지 기준으로 641.1~689.5 g로 대조품종 대비 5.8~10.4% 높았다. 모본 및 대조품종과 대치배양 시 대치선이 뚜렷하고, 균사체 DNA PCR반응 결과 밴드패턴이 모본 및 대조품종과 다른 양상을 보여 서로 다른 품종임을 확인하였다. 본 연구를 통해 발이율이 높고 재배기간을 단축할 수 있는 꽃송이버섯 품종을 육성하였으며, 맞춤형 재배기술 개발에 대한 지속적인 연구와 관심, 그리고 농가보급이 이어지길 기대한다.

국내산 ‘하파’외 4품종과 일본산 ‘Kaneko외 9품종을 2000년 8월 2일에 일반농가포장에 파종하였다. 국내산과 일본산 비교 재배하여 이 지역에 가장 적합하고 우수한 품질의 당근 품종을 선발하기 위하여 실험을 수행하였다. 초장, 엽수 및 엽중은 국내산인 경우 고정종인 ‘중앙’이 각각 60.7 cm, 9.3매, 72.9 g로 가장 우수하였고 교배종에서는 ‘부러운’이 각각 60.3 cm, 8.9매, 65.42으로 가장 우수하였다. 국내산중 근경, 근장 및 근중은 교배종, 고정종 모두에서 ‘비바리’가 52mm, 15.7cm, 275 g으로 우수하였으며 일본산인 경우 교배종은 ‘Sei’이 56 mm, 14.6 cm, 319 g으로 양호하였고 고정종은 ‘Tokai’가 가장 우수하였다. 상품수량은 국·내산에서 ‘하파’(5,472 kg/10a), 일본산은 ‘Kaneko’(5,736 kg/10a)가 가장 높았고 그 외의 품종들은 국내외산 모두 비슷한 경향을 보였다 열근의 발생율은 ‘부러운’이 15%정도로 높았고 고정종인 ‘중앙’이 10% 정도였다. 기근 발생율은 ‘Hidomi’가 9%로 가장 높았고 ‘Sei’과 ‘Tokai’순으로 각각 2%, 6%로 나타내었다. 이로 미루어 볼 때 당근의 주요 상품성을 결정하는 기근과 열근의 발생율은 국내산보다 일본산이 높아 앞으로 재배법을 좀 더 개발하면 국내산 품종이 더 제주지역의 재배에 유리할 것으로 기대되었다.

This study was conducted to evaluated the nature of the variety Tongil(Suweon 213-1) in resistance to the striped rice borer, Chilo suppressalis Walker, comparing with those of Rexoro(susceptible check) and TKM-6(resistant check) selected at IRRI. 1. The striped rice borer moths much more preferred the variety Tongil for oviposition than the varieties Rexoro and TKM-6. The variety Tongil and more egg masses and number of eggs than the varieties Rexoro and TKM-6, while TKM-6 having more egg masses and more number of eggs than Rexoro. This reaction was consistent throughout the test regardless of the number of tillers per hill. 2. In laboratory, preference of larvae for feeding was studied with 5cm of stem pieces of the varieties. The results showed, in contrast to the case of ovipositional preference, that the striped rice borer larvae least preferred the stems of Tongil among the test varieties, while larvae much more preferred the stems of Rexoro than those of TKM-6. 3. The larval weights at 20 days later infested on the 40 day-old plants were the lowest on Tongil among the test varieties. On the variety Rexoro the larvae had heavier body weights(43.0mg), higher pupation(64.9%) and higher adult emergence(83.3%) than those on Tongil(larval weights 30.3mg, pupation 60%, adult emergence 60.7%) and TKM-6(larval weights 35.7mg, pupation 56.3%, adult emergence 51.9%). The pupal weights, however, were not consistent among the test varieties and/or sexes in comparison with the larval weights, pupation and adult emergence above mentioned. 4. Field experiments indicated that the incidence of dead hearts at 70 days after transplanting was relatively higher on the variety Tongil(11.1%) than those on Rexoro(8.9%) and TKM-6(8.4%), and the incidence of white heads at harvest was, in contrast to the dead hearts, lower on Tongil(9.8%) than those on Rexoro(27.4%) and TKM-6(13.9%). At harvest lower larval survival observed on Tongil (49 larvae/40 hills) than those on the susceptible variety Rexoro(104 larvae/40 hills) and on the resistant variety TKM-6(70 larvae/40 hills). The average larval weights collected from three test varieties at harvest were 80.5mg from Tongil, 83.7mg from TKM-6 and 99.6mg from Rexoro. 5. Increased nitrogen fertilizer application to the variety Tongil, the striped rice borer damage was increased. Also, preference of larvae for feeding significantly increased with the increase of nitrogen fertilizer application. 6. Any specific association between the plant characters and striped rice borer resistance could not be found. The variety Tongil even having large number of tillers, short plant height, large stem, broad leaf, etc, had still high preference of moths for oviposition, low preference of larvae for feeding, low damage, and relatively high antibiosis. 7. Resistance of the variety Tongil to the striped rice borers seemed to be associated with the low feeding preference and the relatively high antibiosis, not associated directly with the ovipositional preference.

유기물 시용 및 벼 기상 생태형별 $CH_4$ 발생양상을 구명하고 이를 근거로 논 토양에서 배출되는 $CH_4$ 배출량을 추정하기 위해 미사질 양토에서 시험한 결과를 요약하면 다음과 같다. 1. 시기별 $CH_4$ 배출은 조생종이 2번의 peak를 나타냈으며 중생종과 만생종은 3번의 peak를 나타냈으며 줄기를 통한 $CH_4$ 배출은 온도가 높을수록 많은 경향이었다. 2. $CH_4$배출량은 조생종에 비하여 중생종과 만생종이 높은 경향이었으며, 볏짚 시용구와 비교해볼 때 볏짚 무시용구에서 46%의 $CH_4$ 배출이 감소되었다. 3. $CH_4$ 배출 계수($gm^{-2}day^{-1}$)는 조생종이 0.394, 중생종이 0.407, 만생종이 0.411이었으며, 볏짚 무시용시 $CH_4$ 배출계수는 조생종이 0.198, 중생종이 0.269, 만생종이 0.273이었다.

Despite the universal recommendation to eat a variety of foods, we still do not know whether and to what extent the variety affects dietary quality. This study was performed to evaluate the dietary variety scores as tools for assessing the dietary quality of Korean young adults. The 1-day dietary intake data were collected from 144 male and 214 female college students (>18 years) using the 24-hour recall method Relative nutrient intake compared to Korean Recommended Dietary Allowance (KRDA) as the nutrient adequacy ratio (NAR), were computed Also, the mean adequacy ratio (MAR) was calculated. Dietary variety score (DVS) was determined by counting the number of food items consumed daily, and the dietary diversity score (DDS) by counting the number of food groups consumed daily. Results showed that DVS, DDS and MAR were significantly correlated to each other. The MAR score significantly increased as DDS increased in both men and women. When different DVS (20$\leqDVS\leq$ 30) was evaluated for its sensitivity, specificity, measured prevalence, true prevalence, and positive and negative predictive values towards MAR, DVS 21 was revealed to be optimal dietary variety score as a cutoff point to differentiate Korean young adults with or without an adequate and balanced diet. Nutrient intakes of subjects who had DVS<21 were significantly lower than those of subjects with DVS$\qeq$ 21. These results indicate that the dietary variety score appeared to be an effective tool for evaluating the adequacy of diet in Korean young adults.

고추 (Capsicum annuum L.)의 일대잡종을 이용하여 모본의 유전자형 및 생태형이 약배양 효율에 미치는 영향을 조사하였다. 모본의 유전자형에 따라 약배양 효율에 차이를 보였다. 또한 약배양 효율은 모본으로 배 발생률이 낮은 계통보다 높은 계통을 사용한 교배조합에서 높아 약배양 효율에 세포질 효과가 있는 것으로 나타났다. 또한 생태형에 따른 배 발생 효율은 재래종$\times$피망 교배조합에서 배 발생률이 17.8~46.1%로 가장 높았고, 피망$\times$재래종 조합은 5.4~8.5%의 배발생률을 보여 가장 낮았다. 재래종 $\times$남방계, 남방계 $\times$재래종, 남방계 $\times$피망, 피망 $\times$남방계 교배조합의 배 발생률은 10.5～23.1%로 비교적 중간값을 보였다.
