  • Fragaria ${\times}$ ananassa (Duch.) cultivars, 'Wongyo 3 115' a nd 'Wongyo 3 116', we re bre d as a n inte rme diate parent l ine using heterosis of $F_1$ hybrids in octoploid strawberry. These two new cultivars were developed as inbred lines ($S_9$ generation) propagated from both seed and runners/stolons. 'Wongyo 3115', an inbred line derived from the 'Benihoppe' cultivar, has a semi-upright plant shape showing a vigorless growth habit, weaker than the original 'Benihoppe' cultivar; it has early flower bud differentiation and produces 10 flowers per cluster when grown from healthy seed. 'Wongyo 3115' has low yields of conical type fruit with pink colored skin; average fruit weight is approximately 11 g. The important characteristic of 'Wongyo 3115' is its excellent fruit firmness, firmer than the original variety. 'Wongyo 3116', an inbred line derived from the 'Doyonoka' cultivar, has an upright plant shape, vigorless growth habit, weaker than that of the original 'Doyonoka' cultivar; it has early flower bud differentiation and produces 8 flowers per cluster when grown from healthy seed. 'Wongyo 3 116' has oblate type fruits with red skin and an ave rage weight of approximately 12 g. The important characteristics of 'Wongyo 3116' are excellent fruit shape and higher yield than other inbred lines, although it produces small fruits compared to the original cultivar. Both cultivars have excellent taste, high sugar/acid ratio, and good texture. In regards to disease and pest resistance, 'Wongyo 3115' and 'Wongyo 3116' have a tendency to be sensitive to powdery mildew, anthracnose and the two-spotted spider mite.

  • In this study, we used the random amplified polymorphic DNA (RAPD) technique to evaluate the genetic relationships among 29 grapevine cultivars (Vitis spp.). Sixty selective primers detected a total of 558 polymorphic bands. By UPGMA (unweighted pair-group method arithmetic average) cluster analysis with 558 polymorphic bands, the 29 grapevine cultivars were divided into six major groups at 58.8% genetic similarity. The "Super Hamburg" was clustered in group I. Group II consisted of "Wonkyo RA-23", "Muscat Hamburg", "Tano Red", and "Tankeumchu". Group III consisted of "Alden", "Wonkyo RA -21", "Wonkyo RA-30", and "Dutchess". Group IV included 14 grapevine cultivars ("Heukgoosul", "Heukbosuk", "Suok", "Wonkyo RA-29", "Wonkyo RA-22", "Kyoho", "Pione", "Beniizu", "Golden Muscat", "Jinok", "Doonuri", "Campbell Early", "Delaware", and "Schuyler"). Group V consisted of "Hongdan", "Tamnara", "Hongisul", and "Himrod seedless". Group VI included 2 cultivars ("Cheongsoo", and "S. 9110").

  • This experiment was carried out to investigate effects of dense planting on the growth and productivity in varieties of hot pepper at open field. Three varieties (Joseng jinheung, Weonkyo No. 304 and Bulam house Putgochu) were sowed on Jan. 30th and transplanted on May 12th. The planting densities used were 3,300, 5,500 and 8,300 plants per 10a. The results obtained are as follows: 1) With higher plant density, the plant shape was changed from open-type to upright-type and the yield was increased, presumably due to the increase of leaf area index. 2) LAI and SLA per unit area were increased by denser planting. Wonkyo No. 304 presented the highest LAI and the lowest SLA. 3) Dry matter weight per unit area was also increased, however the LW/SW ratio was tended to decrease on denser planting. 4) Through crop growth analysis, it was determined that CGR and NAR were increased during the early growth stages and became decreased from last June. 5) Light intensity under the canopy formed by denser planting was decreased by 40% measured at 60 ㎝ above the soil surface. The vertical distribution of fruits became concentrated the upper part of plant. Fruit yield per unit area in denser planting was increased as compared to the conventional planting. The number of fruit setting decreased. 6) Generally, no differences in yield were detected in comparison between denser planting and conventional planting harvested on Aug. 30th and Oct. 15th, respectively. But Weonkyo No. 304 increased yield by 18% in denser planting.

  • Wongyo Lee KwangSa (1705~1777) is a scholar and artist who represented an era in the period of change and revival of Korean culture and art in the 18th century. In 1755 (31st Yeongjo), he was transferred to Sinjido due to the Naju Byeokseo Incident, and died in exile for a total of 23 years. He tried to correct the problems of the flow of calligraphy in common writing and the flow of calligraphy in the Joseon Dynasty, and wrote 『Wonkyo Seogyeol』. By realizing an original artistic state that is evaluated as having completed the 'Dongguk Jinche', which is a unique and subjective and self-conscious calligraphic flow of the Korean people who wants to reestablish the essence of calligraphy, it has had an absolute influence on the Honam area. Wonkyo's calligraphy aesthetics are developed into the beauty of ChanggyeongBalsog based on Shimjin of Yangminghak, Yanggangmi of Power of controlling all the stands of brush hair, and Vitality of Push out the brush with all your might. He recognized free sculpting and energetic, muscular strokes as the key to calligraphy, and suggested honing the old tombstones written in JeonYe. Vibrant stroke means that Cheongi naturally permeates in the midst of Samgwa and Gilgok, and the brush is operated with Push out the brush with all your might of Power of controlling all the stands of brush hair. These calligraphy aesthetics radiated sinchae with geungol and singi, and were expressed in Wongyo font, full of vitality as a living creature, pursuing the unique pilgrimage and pilgrimage unique to our nation, revealing the true nature of nature.

  • BACKGROUND: The scab, which is caused by Venturia nashicola, gives serious damages to pear trees. 'Niitaka' accounts for 82% of areas in pear cultivation. However 'Niitaka' is a scab susceptible cultivar. So, most of Korean farmers who growing pear trees have suffered by economic losses with the scab. In this research, we evaluated the scab resistance among elite pear seedlings to clarify genetics about the scab resistance. And we analyzed photosynthetic features with these seedlings to develop suitable cultivar which is advantageous for producing quality fruits during the growth and development of plants. METHODS AND RESULTS: We measured the rates of scab incidence among seedlings in a field experiment condition and an in-vitro test. An in-vitro test has been done with field experiment-based results. We made plant materials by grafting branches of each seedlings with 'Kongbae' rootstocks. And they had been grown for one month. Then, scab conidia suspension is sprayed to seedlings and sustained for 40 days under the controlled environment. As the results, 6 seedlings displayed lower incidence rates than other seedlings and 'Niitaka'. We also measured instant photosynthetic rates of each seedlings to determine the correlation between photosynthetic rates and fruit characteristics. However, it seemed that there is no correlation between them. CONCLUSION(S): Among the seedlings, 6 seedlings displayed the higher resistance to scab than other seedlings and 'Niitaka'. This characteristics is considered to be come from the gene expression of European pear. And we found that photosynthetic rate in trees rarely does not influence the fruit characteristics. It is considered to be affected by cultivar's own characteristics.

  • Near the Gapcheon, a new suburban city will be developed by the Ministry of Construction and Transportation, and a intracity highway will be constructed by Daejeon Metropolitan City. By these new plans, rapid disruption of environmental conditions near the Gapcheon will be anticipated. The new construction of the city and highway will raise a problem of environmental pollution and disruption of natural status of this area, and will have an adverse influence to environment of the Dunsan area and an industrial complex which are located at the downstream of the Gapcheon. This re-search was conducted on the Gapcheon area, Daejeon (Gasuwongyo to Wonchongyo) from August, 2001 to June, 2002 years. Microorganisms of Gapcheon are three forms, 17 varieties, 105 species, 58 geneva, 31 families, and totalled 125 taxa. And zooidal micro-organisms, one varieties, 16 species, 12 genera, eight families, and totalled 17 taxa. Hydrogen ion concentration of the stream is ranged from 7.10 to 9.98 with great variation, especially high below bridges of Gasuwongyo and Mannyeongyo. The clean water quality of the stream is still maintained very well due to dense distribution of diverse aqua-tic and swamp plants. Furthermore, species diversity of microorganisms in the stream does help to purify the quality of water, and to keep the health of the Gapcheon as natural. More environmentally controlled and continuous efforts to keep the Gapcheon in a natural status and to purify the quality of water should be made by Daejeon Metropolitan City Officials who ave now spending about 6G,5()0 million won for overall conservation plans of the stream (from 1999 to 2003 years).

  • Strawberry is an out-crossed crop that is relatively sensitive to inbreeding, and as a result, most of breeding programmes in strawberry have been based on selection breeding where elite parents are selected from intercrossing. Also, pedigree breeding has been successfully employed in a number of instances to concentrate genes of interest. Therefore, in order to obtain inbred line having the genotype of excellent combining ability by selfing and incrossing to improve breeding efficiency of strawberry, elite varieties were self-pollinated. From the selfing line of "Benihoppe" cultivar, we selected "Wongyo 3111" having excellent horticultural traits such as plant vigor, sugar content and fruit hardness among these progenies. "Wongyo 3111" shows erect plant type, vigorous growth habit, early flower bud differentiation with 16~17 flowers per cluster. Fruits of "Wongyo 3111" are conical type having a bright red skin color, and 17.2 g in an average weight. Also that have a relatively more high sugar/acid ratio and firmness than check cultivars as sugar content of 11.3oBx, acidity of 0.50% and firmness of 21.7 g/$mm^2$. But although yield of "Wongyo 3111" is not significantly different from check cultivars, its marketable yield is remarkably lower than that of check cultivars because of poor fruit-setting under low temperature. Disease and pest reactions of "Wongyo 3111" are more sensitive to powery mildew, anthracnose and spotted spider mites than check cultivars. Therefore, "Wongyo 3111" is suitable for intermediate parent line better than as a cultivation cultivar.

  • In order to select excellent cross parents in strawberry breeding, 11 varieties were self-pollinated and tested their progenies. Among the 11 varieties, 'Akihime', 'Maehyang' and 'Seolhyang' showed superior in plant vigor, disease resistance and yield. Combining ability was tested using 15 progenies obtained from crosses between 3 selected varieties as seed parents and 5 varieties as pollen parents. Plant vigor was the strongest when 'Akihime' was used as a seed parent while ripening time tended to the fastest when 'Seolhyang' as a seed parent. Average fruit weight of the crosses 'Seolhyang' ${\times}$ 'Tochiotome', 'Seolhyang' ${\times}$ 'Geumhyang', 'Seolhyang' ${\times}$ 'Wongyo 3111' and 'Akihime' ${\times}$ 'Wongyo 3111' were above 18 g for marketable fruits. Fruit hardness was superior at crosses of 'Maehyang' as a seed parents to other crosses combinations, especially 'Maehyang' ${\times}$ 'Tochiotome'. Soluble solid contents (SSC) was not significantly different among cross combinations. The best cross combination for marketable yield was 'Akihime' ${\times}$ 'Wongyo 3111', followed by 'Seolhyang' ${\times}$ 'Geumhyang', 'Maehyang' ${\times}$ 'Geumhyang', 'Akihime' ${\times}$ 'Tochiotome', in order.
