The green peach aphid was relatively the majority(36.9-72.3% ) among all alate aphids collected from tobacco plants. Density of glatae was relatively lower on varieties Tl 1112 and Br 21 than on Va 115 or Y S A among seven varieties tested. However, no considerable difference was observed in general biology of nymphs produced by alatae on the tobacco varieties. About 55% of alate green peach aphid collected from tobacco fields produced progency, and over 80% of the nymphs became adults on cut tobacco leaves in petri dish. Adult longevity of both alate and apteral green peach aphid was shorter, and numbers of nymphs produced by both types were lower in summer than in autumn. Apterae produced more nymphs than alatae, but the longevity of apterae was shorter.

Present work was attempted to investigate the karyotype, the reciprocal translocation of chromosomes and the geographical distribution of three Paeonia species grown wild in Korea with the aim of elucidating the taxonomical affinities of the species. Prior to conducting these works, it was required to clarify the karyotypes of the cultivated varieties of P. albiflora which has been grown since long time ago in this coundtry for medicinal value. Present report is part of the series of karyotype studies now being extensively conducted using varieties (or lines) of P. albiflora collected across the country. Arm ratio, number of trabant, kind of trabant chromosomes and karyotype formula are different among the six cultivated varieties. Excepting one, five varieties used had invariably trabants on D and E chromosomes while no trabant was found in C chromosome.

본 시험은 자운영(Astragalus sinicus L.)의 월동과 사료생산성을 구명하기 위하여 경기도 남양주 군에 있는 고려대학교 실험농장에서 실시되었다. 수집종 논산, 임실, 장흥, 청남, 중산 및 도입종 PI 241587을 노지와 vinyl mulching 처리조건에서 월동시켜 재배 시험하였다. 얻어진 결과를 요약하면 다음과 같다. Vinyl mulching 처리효과는 통계적 유의성이 없었다. 자운영 품종들의 평균 월동률은 노지조건에서 88%였다. 생초중과 건초중은 5월 6 일과 5월 21일 예취 모두 논산과 임실이 높았다. 노지조건에서 자운영 품종들의 10a당 평균 생초수량은 5월 6일 예취는 1,583 kg이었고 5월 21 일에는 4,017kg이었다. 건초의 평균 조단백질 함량은 5월 6 일 예취는 21.3%였고, 5월 21일 예취에서는 19.2%였다. 그러나 5월 6일 예취된 건초의 평균 조섬유 함량이 5월 21일 예취에 비하여 낮았다.

To analyze their isoflavones contents by HPLC analysis during two years on 60 collected old local traditional soybean varieties from various districts of Korea was conducted. There was a yearly variation in the seed isoflavon concentrations. The total contents on 5 isoflavones were in the range from 16.21mg/g to 25.21 mg/g and from 6.47 mg/g to 15.44 mg/g, in 1997 and 1998, respectively. Collected soybean from Gunsnsi-1(25.21 mg/g) in 1997 and from Gangjingun-3 (16.50 mg/g) in 1998 showed the highest amount of isoflavones as compared with other collected soybean varieties. The highest amount among 5 isoflavones was genistin as 48.45% and 49.73%, in 1997 and 1998, respectively, indicating the genotypic variation in seed isoflavon contents of local soybean cultivar. Our data suggest that it may be feasible for improving soybean variety with higher antioxiadtive activity and substances.

In last study, Genome-Wide Association Studies (GWAS) was conducted for cadmium content of 295 rice varieties including 137 rice core set and 157 Korea breeding varieties collected from Kongju National University. The results showed that 9 varieties had SNP allele and amino acid substitution in exon of chromosome 1. This study was aim to understanding mechanism of cadmium uptake to confirm correlation of cadmium and other mineral nutrients (Cu, Mn, Fe) among 9 rice varieties. Nine varieties were planted on polluted soil of mine in Korea and cadmium content in root, stem, leaf and it's brown rice was analyzed by ICP-MS (Inductively Coupled Plasma Mass spectrometer, Agilent 7700E, US). Results of this study showed that mechanism for cadmium uptake and accumulation was diversity among varieties. Chin-nong and Ho-nong contained higher levels of cadmium in root, but contained relatively lower levels cadmium in brown rice than other varieties. Cheong-nam, Nam-pyeong, Gan-cheok, Suan absorbed high levels of cadmium through root and then accumulated high cadmium to brown rice. Meanwhile, Yeong-deok and Su-kwang absorbed lower cadmium in root, but high cadmium was accumulated in brown rice. Correlations between cadmium and other mineral nutrients (Cu, Mn, Fe) were analyzed by using SPSS statistics 20. The contents of iron in leaf had minus correlation (p<0.05) with cooper and cadmium in root, cadmium in brown rice. Therefore understanding of cadmium uptake mechanism among varieties will be used to basic data for further breeding and phytoremediation.

This experiment was conducted to find out the consumptive use of irrigated water for calculation of duty water in paddy rice. Tall statured Japonica rice varieties, Nongbaek (early), Jinheung (medium) and Akibare (late), and short statured Tongil typed varieties, Josaeng Tongil(early), Suweon 264 (medium) and Suweon 258(late) were planted on the experimental farm of Kon-Kuk University in 1979. The results obtained in this study were as follows: 1. During the experimental period, the daily mean temperature was almost similar, the relative humidity was higher as much as 2.8%, the amount of rain fall was 100mm less and the pan evaporation was 70mm less compared with those of 30 years average, respectively. 2. The paddy soil was silty loam, which was suitable for the rice cultivation. 3. Varietal differences were find out for plant height, culm length, number of tillers, number of panicles, heading date, matured grain ratio, 1000-grain weight and rough rice yield. This difference might he the cause of varietal difference of the consumptive use of irrigated water during the rice growing period. 4. The evapotranspiration was gradually increased after transplanting and showed the peak from booting to heading stage of rice varieties. The average evapotranspiration through the whole growing period was 5.67-5. 80mm/day for tall statured Japonica varieties, and 5.99-6. 39mm/day for short statured Tongil typed varieties. 5. The ratio of evapotranspiration to pan-evaporation through the whole growing period was 1.49-1.50 for Japonica varieties, and 1.60-1.66 for Tongil typed varies. 6. Average amount of percolation in paddy field was 3. 62mm/day through the whole growing period of rice plant. 7. K-value in Blaney & Criddle formula was 0.94-0.98 for Japonica varieties and 1.02-1.08 for Tongil typed varieties, and coefficient consumptive water use (Kc-value) was 0.95-1.02 for Japonica varieties and 1.04-1.12 for Tongil typed varieties in this study. The modified coefficient for consumptive water use, which was calculated from data collected through the country including this study, was as follows;

The status of corn genetic diversity in the uplands of Sarangani in Southern Philippines was investigated using 12 morphological traits subjected to multivariate statistical analyses. Information about traditional farming, post-harvest and storage practices were also elicited especially in relation to losses of traditional varieties, a phenomenon known as genetic erosion. While a handful of farmers still plant traditional corn varieties in the remotest areas, a significant number had already shifted to genetically modified corn. Furthermore, principal component analysis (PCA) reduced the 12 morphological traits into 5 principal components and identified ear length and ear weight to be major contributors to variation. Cluster Analysis, on the other hand, formed two distinct groups but failed to give information about intra-cluster variability among the 32 collected corn accessions. These results warrant that more informative morphological traits and that molecular markers will be used to obtain a better picture of genetic diversity in Sarangani upland corn. Molecular analysis is also needed to establish genetic identities of these cultivars and to detect gene introgression from GM varieties into the gene pool of farmers' corn varieties. These analyses are imperative for the conservation of traditional corn varieties before they disappear in the Sarangani uplands because of shifting priorities of upland farmers.
