1975년 6월부터 10월 사이에 전남 곡성 서계리에서 개간 재배되고 있는 과수지대를 중심으로 그 주위의 호수나방유예의 식초 분포조사와 발생소장 및 당도를 조사하였다. 그 결과를 요약하면 다음과 같다. 1. 흡수나방 유충의 중요한 식초는 청미래덩굴, 자귀나무, 댕댕이덩, 정의다리, 개굴피나무이며 개굴피나무는 표고 500m 이상 고산지역에 분포되어있는 반면 다른 기주들은 표고 100-300m의 지역에 많이 분포되어있다. 2. 발생소장을 보면 6월 25일부터 발생하기 시작하여 10월 4일까지 출현하였는데 10월 4일까지 출현하는 자두와 복숭아에서의 나방방 최성기는 7月 13日경이며, 포도에서는 8月 310경이였다. 3. 6년 25일-10월 4일 사이에 13종의 흡수나방을 채집하였는데 가장 많이 채집된 것은 무궁화밤나방, 애우묵밤나방, 우묵밤나방, 으름나방으로 전체의 을 차지하였다. 4. 복숭아와 자두의 당도를 보면 당도가 높을 수록 흡수나방의 피해는 컷으나 산도와는 큰 차이가 없었다.

This study was carried out to build a database system for amylose and protein contents of rice germplasm based on NIRS (Near-Infrared Reflectance Spectroscopy) analysis data. The average waxy type amylose contents was 8.7% in landrace, variety and weed type, whereas 10.3% in breeding line. In common rice, the average amylose contents was 22.3% for landrace, 22.7% for variety, 23.6% for weed type and 24.2% for breeding line. Waxy type resources comprised of 5% of the total germplasm collections, whereas low, intermediate and high amylose content resources share 5.5%, 20.5% and 69.0% of total germplasm collections, respectively. The average percent of protein contents was 8.2 for landrace, 8.0 for variety, and 7.9 for weed type and breeding line. The average Variability Index Value was 0.62 in waxy rice, 0.80 in common rice, and 0.51 in protein contents. The accession ratio in arbitrary ranges of landrace was 0.45 in amylose contents ranging from 6.4 to 8.7%, and 0.26 in protein ranging from 7.3 to 8.2%. In the variety, it was 0.32 in amylose ranging from 20.1 to 22.7%, and 0.51 in protein ranging from 6.1 to 8.3%. And also, weed type was 0.67 in amylose ranging from 6.6 to 9.7%, and 0.33 in protein ranging from 7.0 to 7.9%, whereas, in breeding line it was 0.47 in amylose ranging from 10.0 to 12.0%, and 0.26 in protein ranging from 7.0 to 7.9%. These results could be helpful to build database programming system for germplasm management.

There has been known C3G (Cyanidin-3- Glucoside), D3G (Delphinidin-3-Glucoside), and Pt3G (Petunidin- 3-Glucoside) were main anthocyanin pigments in black-seeded soybean. Anthocyanin contents of total 1,032 black-seeded soybean germplasms were analyzed by HPLC. Average of total anthocyanin content was 11.67 mg/g on the all materials ranged from 0.54 to 23.45 mg/g. Mean value of C3G, D3G, and Pt3G contents in all black-seeded soybeans were 8.81, 1.78 and 0.79 mg/g, respectively. Environmental conditions influenced anthocyanin contents during seed development. Delayed flowering, especially of later maturing germplasms, has been showed to result in increased anthocyanin content. So, prolonged maturation period germplasm is generally higher than that of shorten genotypes. It may be concluded that the higher levels of anthocyanin content was associated with the late dates of harvest maturity. Also larger seeds showed high anthocyanin contents than smaller. That inclination is similar in C3G’s occasion because C3G content contribute highly to total anthocyanin content than other pigments.
