  • 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.

  • The experiment was carried out to investigate the adaptability of freezing process with thirteen strawberry varieties cultivated in Suwon, Pusan and Chunju area. Six of these were local varieties and the others were varieties imported from the United States of America. Each strawberries variety was analysed chemically to determine value of soluble solids, acidity (calculated as citric acid) and deepness of color. Frozen products were prepared by a general method adding sugar to $28^{\circ}\;Brix$. Local varieties Haengok, Bokuh, Keikwan and Daehak No. 1 were not suitable for making into frozen products because of excessive white color in their centers. Blakemore, an imported variety, was best as to color. Chemical analysis showed that imported varieties have higher acidity, and lower content of soluble solids. In a sensory test conducted by fifteen members of Agriculture and Fishery Development Corporation, deeper colors of strawberries did not receive a generally favorable response, and it was found that strawberry colors favored by the America were not liked by Korean well.

  • Tobacco leaves cultivated in Korea, U.S A., Greece and Turkey were analyzed for their essential oils that are solanone, nor- solanadione, damascenone, dana scone and mesa stigmatrienone (4- isomer). Regardless of tobacco varieties and cultivated localities, solanone was the most abundant. Among them particularly, Basma has the highest amounts of the solanone than other varieties. Flue-cured tobacco leaf has much higher amounts of damascellone than burley and aromatic tobacco leaf do. U.S. A. flue-cured, U.S. A. burley and Basma clave much higher concentration of solanone than corresponding Korean varieties, but significant differences could not be observed in other components. The order of total amounts of 8 essential oils in tobacco varieties were as follows; Aromatic) Burley) Flue-cured

  • In recent, a demand for sweetpotato cultivation technology to expand the cultivated area of field crops in paddy fields is increasing. This research was carried out to establish suitable varieties and cultivation techniques for mass production of sweetpotato for processing raw materials. For the selection of varieties suitable for cultivation in rice fields for each processing purpose, 12 varieties in 2018 (8 varieties for starch, 4 as dried, chips and beverages), and 6 varieties in 2019 (4 varieties for starch including 'Daeyumi'; chips, semi-dried 'Pungwonmi'; beverage and coloring 'Shinjami') were used. Sweetpotato stems were planted in mid-May and harvested after 120 days to investigate the yield. Results revealed that the yield of sweetpotato (2019) for starch production, varied with variety as 'Gogeonmi' 3,926 > 'Jinhongmi' 3,428 > 'Daeyumi' 2,873 > 'Singeonmi' 2,752 kg/10a. The starch content was 20.2% in 'Daeyumi', 18.2 in 'Gogeonmi', 21.2 in 'Singeonmi', and 20.6% in 'Jinghongmi'. The total amount of starch was higher in 'Daeyumi' (730 kg/10a) and 'Gogeonmi' (731 kg/lOa). The yield of chips and edible varieties 'Pungwonmi' was 4,688 kg/10a. The yield of 'Shinjami' of purple variety such as beverages and powder was 3,139 kg/10a. Aaa result of evaluation sweetpotato yield by waterlogging treatments on different growing stages in paddy fields, the yields of 'Daeyumi' and 'Jinhongmi' varieties treated with waterlogging at the storage root formation stage decreased by 11.8% and 11.7%, respectively, compared to the control. In the case of waterlogging treatment at storage root swelling stage, Both varieties showed the lowest yield reduction at 7.0% and 4.8%, respectively. Based on these results, stable production and substitution effect of processing raw materials can be expected by cultivating sweetpotato varieties suitable for paddy cultivation.

  • Health beneficial properties of soybean [Glycine max (L.) Merr.] isoflavones are well known. The objectives of this study were to determine and compare the isoflavone composition and concentrations of soybean varieties grown in different cultivated regions of Vietnam (i.e., upland and lowland). Total and individual isoflavone composition and concentrations were determined by high-performance liquid chromatography (HPLC). Total isoflavone concentrations varied from 1153 to $6604{\mu}g\;g^{-1}$ and averaging $3354{\mu}g\;g^{-1}$ across environments and varieties. In the lowland region, the highest total isoflavones concentration was observed in M103 cultivar ($5653{\mu}g\;g^{-1}$) and the lowest in VX9-3 ($1153{\mu}g\;g^{-1}$), whereas in the upland region the highest and lowest concentrations were in M103 ($6604{\mu}g\;g^{-1}$) and DT93 ($1938{\mu}g\;g^{-1}$), respectively. Across varieties, average total isoflavones concentration was higher in the upland than lowland region (3728 vs. $2980{\mu}g\;g^{-1}$). The malonylglucosides and acetylglucosides concentrations in upland soybean varieties were higher than those from the lowland region. Despite the presence of Genotype (G) x Environment (E) interactions, varieties with consistently high (M103) and low (VX9-3, DT93) isoflavone concentrations across environments were identified. This is the first report of isoflavones in Vietnamese soybean varieties, revealing large variation in isoflavones concentration and profile among different varieties and cultivated regions. Results will be useful in selecting high-isoflavones soybean varieties for growth in tropical regions.

  • 당근뿌리혹선충(Meloidogyne hapla)에 대한 저항성품종을 선발하고자 175개 고추품종을 대상으로 조사하였다. 그 결과 재래종 15품종(IT 102794, 104806, 105516 등)과 도입종 2품종이 저항성이었고 재배품종 중에서는 홍탑고추, 강산고추, 홍실고추와 부강고추가 중도저항성이었다. 저항성반응을 보인 품종에서는 감수성인것에 비하여 선충의 침입수도 적었고 발육도 부진하였다. 또 에스테라제와 퍼옥시다제의 활력에서 저항성 고추품종의 뿌리는 감수성인 것에 비하여 현저히 높았다.

  • In spite of their inferior quality, pale yellow flue-cured tobacco varieties (N. tabacum L.) are being cultivated as pre-crop of rice in paddy field because of its early leaf maturity. Fertile and male sterile Hicks as green variety , three pale yellow varieties and six single cross $F_1$ hybrids between green and pale yellow varieties, were evaluated. Fertile $F_1$ hybrids were similar to pale yellow varieties in early leaf maturity, curing characters and nicotine contents, where-as they were lower in total nitrogen, higher in reducing sugar comparing to those of the pale yellow varieties.

  • Nine accessions of red rices collected from different regions were tested for germination characteristics in relation to seed maturity and several storage conditions after harvest. No red rice seeds germinated at five days after anthesis (DAA). Wanjuaengmi (long-grain red rice) seeds at 10DAA germinated up to 30% of total samples, producing only abnormal seedlings, whereas 10D-AA-seeds of normal cultivar showed only 3.3% germinability. Some red rice seeds absorbed more water than cultivated varieties, and showed less decrease in germination rate than cultivated varieties when seeds were exposed at -1, -5 or -1$0^{\circ}C$ for up to 60 hours after soaking. Red rice accessions maintained more than 95% germination when stored. indoor for 120 days. Two short-grain red rices showed about 50% germination when overwintered in the field, while other long-grain red rices and cultivated rices germinated less than 10%. Germination of seeds overwintered in clay loam soil was lower than that in loam soil, and seeds on surface germinated less than those in 1~7cm depth.
