We bred a mulberry cultivar named Palcheong, through local adaptability test, which is under registration as a new cultivar for fruit production. Local adaptability test had been carried out at four places (Suwon, Kongju, Wanju, and Jinju) for seven years from 2007. This is belonging to (Morus Lhou(Ser.) Koidz.) selected among mulberry genetic resources preserved in Suwon. Its sex expression was hermaphrodite, which can be used for the production of seedling for fruit production by artificial crossing as pollen parent Palchung showed lower yielding in fruit productivity by 16% compared to control cultivar 'Chungil (Morus alba L.)' for five years. Although Palchung was higher in sugar content of mulberry fruits, it was bigger than that of 'Chungil'. It is adaptable to every where except the places where cold damage and sclerotic disease happen frequently.

A total of 520 overwintered sclerotia were collected from surface of soil under mulberry trees in six locations in Korea during February in 2006 and 2007. The collected sclerotia were tested for their germination in vitro and identified based on their morphological characteristics. Out of all sclerotia tested, 52.3% of the sclerotia germinated and produced two types of apothecia. The two types of fungi occurred from the sclerotia at the ratio of 49.8 vs. 50.2. The fungal type with cup-shaped apothecia was identified as Ciboria shiraiana and another type of fungus with club-shaped apothecia as Scleromitrula shiraiana. Taxonomy and distribution of the two sclerotial fungi were described and discussed.

The aim of this study was to evaluate the effects of three different mulberry cultivars extracts on serum lipid contents in ovariectomized estrogen-deficient rats. Sprague-Dawley female rats were randomly assigned to the following groups: sham-operated rats (sham), ovariectomized control rats (OVX-control), ovariectomized rats supplemented with $ 80\% $ ethyl alcohol extracts from various kinds of Tajikistan mulberry (OVX-TM), Korea mulberry (OVX-KM) and China mulberry (OVX-CM) at 200mg/kg bw/day, respectively. The mulberry extracts were orally administrated at 1mL per day. The body weights of OVX rats were significantly heavier than the sham-operated rats at all values (p <0.05). The ovariectomy caused an expected increasing in the levels of serum total cholesterol and triglyceride. The serum HDL-cholesterol level on the OVX-TM, OVX-KM and OVX-CM groups were higher than in the OVX-control group.

We conducted this study to investigate the effect of methanol extract from Mulberry Fruit on the lipid metabolism and liver function in cholesterol-induced hyperlipidemia rats. We used 5 Mulberry Fruit varieties, including Daeryukppong, Kuksang 20, Subongppong, Wild variety and Cataneo. The yield of methanol extract from freezing dried Mulberry Fruits was 43.5-64.6%. Animal treated with Wild variety from Mulberry Fruit showed the decrease in body weight, food efficiency ratios, serum triglyceride (85%), and GOT value (86%). Our results suggest the hypolipidemic action of Wild variety from Mulberry Fruit.

Mulberry fruit is common to keep a frozen storage because of the very high water content. Because freezing-storing cost is generated before the processing or sales, farmers of mulberry fruit production are weighted in financial burden. In addition, mulberry fruit has difficulty in expanding consumption by made in the simple processed products like the mulberry jam, mulberry juice, mulberry enzyme, alcohol, etc. Recent, frozen fruits including frozen blueberries, frozen strawberries, frozen mango, frozen rich, frozen mulberry fruit has been started to sell in the large discount stores and convenience stores. However, there is restricted sales in only special place that have the frozen distribution facilities. So, for the income improvement and consumption promotion of mulberry farmers facing these difficult situations, we developed the processing method of semi-dried mulberry fruit using the vacuum freezing dryer. The frozen mulberry fruit which was stored below $-40^{\circ}C$ is to dry in a vacuum freeze dryer, at $30{\sim}35^{\circ}C$, 23 ~ 24 hours. Semi-dried mulberry fruit seperated respectively. It had soft texture, and maintained shape, size and flavor. In particular, semi-dried mulberry fruit can be stored at room temperature.

BACKGROUND: Globally, mulberry (Morus sp.) is exploited for feeding leaf to silkworms in order to obtain silk fiber or for animal feedstock production. Also, mulberry fruit is known to a by-product that was produced from mulberry tree after harvesting leaves for silkworm rearing, as a yield and consumption of mulberry fruit was increased, it has been fixing to a newincome crop. Mulberry leaves and fruits are used for the health benefits of human beings. Mulberry contains various bioactive components, such as alkaloids and flavonoids. Mulberry flavonoids are an important part of the diet because of their effects on human nutrition. The flavonoids in mulberry leaf and fruit of 'Suhyang'(Morus alba L.) were determined. METHODS AND RESULTS: Flavonoids for mulberry leaf and fruit of 'Suhyang' were analysed using ultrahigh performance liquid chromatography coupled with diode array detection and quadrupole time-of-flight mass spectrometry (UPLC-DAD-QTOF/MS)technique. An UPLC-DAD-QTOF/MS system was used, and identification of mulberry leaves constituents was carried out on the basis of the complementary information obtained from LC spectra, MS ions, and MS/MS fragments. The mulberry leaf (16 flavonoids) and fruit (9 flavonoids) were isolated and analyzed from Suhyang using UPLC-DAD-QTOF/MS chromatogram. To the best of our knowledge, Quercetin 3-O-(6"-O-malonyl) glucoside and quercetin 3-O-rutinoside (rutin) was detected on the highest content in leaf and fruit, respectively and further research will be devoted to evaluate their biological activity. CONCLUSION: Obtaining information about the concentration of functional materials in mulberry leaves could contribute to the development and promotion of processed, functional products and offer possible industrial use of 'Suhyang', holding promises to enhance the overall profitability of sericulture.

For the purpose of developing natural antioxidant, the antioxidative activity of phenolics isolated from Korean Mulberry(Morus) fruits was determined. Optimum extracting condition for phenolics were 60$\%$(v/v) ethanol. The content of rutin and isoquercetrin as flavonoids were 82.83 mg/100 g and 43.23 mg/100 g respectively. The 2,2'-azinobis-3-ethyl benzothiazoline-6-sulfonic acid radical decolorization and antioxidant protection factor (PF) were determined with extracts from Mulberry fruits. Results showed 98$\%$ inhibition on ABTs by 80$\%$ ethanol extract and 1.25 PF on antioxidant protection factor by 60$\%$ ethanol extract. Electron donation ability on DPPH was higher 60$\%$ ethanol extract than other ethanol extracts. Also, hydroxyl radical scavenging activity of extracts was higher 60$\%$ ethanol extract than other extracts.

Vermicompost, manure, compost and organic fertilization are ecofriendly. Nowadays, many products resulted from sericulture consumed by humans such as mulberry leaves, fruits, mulberry tea, silk and natural silk cosmetics. Soil applications of three treatments with vermicompost (0.5, 1 and 2 tons per 0.42 hectare) and recommended rate of mineral fertilizers of nitrogen phosphorus potassium were used for investigation. Impact of fertilization on mulberry plant traits of moisture, number of shoots/tree, total shoots length/tree, number of leaves/shoot, number of leaves/ (100g), leaf yield/tree and leaf yield of fadden/season were recorded. In addition the effect of fertilization on larval and cocoon characters of young instar duration, fifth instar duration, total larval duration, larval mortality percentage, weight of third instar larvae, weight of fourth instar larvae, weight of fifth instar larvae, fresh cocoon weight, fresh shell weight, pupae weight, cocoon shell ratio, silk productivity, cocooning percentage, pupation ratio, number of cocoons/ liter, crop cocoons by number, crop cocoons by weight, fecundity and fertility. Using vermicompost treatment was enhancing plant characters. Treatments of V₃, V₂ and V₁ were shortage young, fifth and larvae durations. Mostly feeding silkworm during the whole larval duration on treated mulberry leaves with vermicompost improving the traits average. Using vermicompost for fertilization by rate of V₃ and V₂ is better than others for cocoon characters for females and males.V₃ and V₂ of vermicompost per 0.42 hectare is recommended for rearing mulberry silkworm instead of mineral fertilization.
