成圭秉,柳根燮 한국잠사학회 1990 한국잠사곤충학회지 Vol.32 No.2

To make clear the changes of the amount of reserve substances in the bark of stem and root of mulberry graftages after planting, studies were carried with mulberry graftages classified into three groups of 7.0~7.9mm, 9.0~9.9mm and 11.0~11.9mm in diameter of stems at 3cm above their base. The results obtained were as follows: 1. The dry weight of stem and root bark gradually decreased with growth of new shoots till about five weeks after planting, and from then it increased. 2. The duration of new shoots growth depending on the reserve substance was limited for 6∼7 weeks after planting. In no fertilized group, the length of new shoots increased up to 6~7 weeks, from then decreased. 3. Dry leaf yield three weeks after planting was found to be no difference in the same diameter of saplings between with and without fertilization. 4. The content of chlorophyll in the leaves was higher in thicker group and in fertilized group than thinner and no fertilized one, respectively. 5. There was no difference in the amount of carbohydrates of the bark of stem and root among the stem diameters. There was a transient increase in the amount of total sugar in the bark of stem and root in the first three weeks after plantillg, followed by gradual decline of to five weeks. The amount of reducing sugar in the bark of stem and root increased both in fertilized and in no fertilized group up to three weeks after planting, and then it decreased. There was a gradual decline in the content of starch in the bark of stem and root both in fertilized and in no fertilized group up to five weeks after planting, followed by gradual increase.

New Mulberry Cultivar, Milsungppong, was selected from Fl seedlings obtained by crossing the female, 4X Keomseolppong, and the male, Kaeryangppong. Local adaptability test has been carried out at five Places(Suwon, Chunchun, Cheongju, kongju and Sangju) for four year since 1992. Leaf quality was tested by silkworm rearing for two sildworm rearing seasons(spring and autumn) at Suwon in 1995. From these tests, Milsungppong was found to be superior to control cultivar, Kaeryangppong, in productivity, footability and shoot cold injury. The new cultivar, Milsungppong, has following agronomic characteristics as compared with Kaeryangppong, the most prevailing cultivar in Korea. It is triploid cultivar belonging to Morus bombycis KOIDZ with the leaf shape of five lobes, sprouting in spring nearly the same to the Kaeryangppong (Morus alba L.). high leaf yielding of 25% compared to Kaeryangppong (Morus alba L.) and the medium degree of cold resistance. It is adaptable to every where in Korea except the area cold injury broken out habitually. Milsungppong is recommended to rear silkworms not only in spring but also in autumn besides for young silkworms.

Nucleotide sequence in internal transcribed spacer (ITS) regions of ribosomal DNA among mulberry varieties (Morus species) were analyzed in order to identify the possibility of classification for the species. The variations in the ITS regions were compared among 9 mulberry varieties and doe variety of Cudrania species as an outgroup. ITS 1 region of the varieties ranging from 219 to 220 bp in length was 49-50 bp shorter than ITS 2 region. Of 510 sites in the ITS 1 and 2 regions, 148 sites were potentially variable, of which 52% and 48% sites were distributed in ITS 1 and ITS 2 regions, respectively. By pairwise comparisons on the nucleotide sepuences in the ITS 1 and 2 regions among 9 mulberry varieties, they were lassified into 5 groups. Diergence values of the sequences, however, were considerably low ranging from 0 to 1.3%. Especially, there was no divergence among Backasipmunja, Chungilppong and Milsungppong and Jungyasang, Ssarigol II and Yulbon, respectively.

지금까지 오디는 누에 사육을 위한 뽕나무 재배를 하고 남은 나무에서 생산되는 부산물로 여겨져 왔으나, 2003년부터 오디 생산을 위한 뽕나무 재배기술이 보급되면서 오디의 생산량과 소비가 크게 늘어나 새로운 소득작목으로 정착되어 가고 있다. 그러나 기상재해에 의한 피해로 오디 안정생산이 문제가 되고 있어 농업재해보험 도입이 필요하다. 농업재해 보험 도입을 위한 기초 연구로서 2012년 1차 조사를 하였으며, 2014년에 2차 조사를 통하여 데이터를 보완하기 위하여 오디 생산용 뽕나무 재배양식, 수형, 품종별 결실수, 오디 균핵병 발생양상, 생산량 및 판매가격 등을 조사하였으며, 그 결과는 아래와 같다. 결과모지 1m당 결실 오디수는 동일 품종의 수령별, 동일 품종의 수형별 오디 결실수는 큰 차이가 없는 것으로 나타났고, 오디균핵병 발병은 재배지역, 품종에 따라 차이가 큰 것으로 나타났으며, 수형에 따른 발병에는 일정한 경향이 없었다. 10a당 수확량은 과상2호 품종의 경우 부안지역에서는 식재연차에 따른 수확량에는 일정한 경향이 없었지만, 정읍지역은 식재연차가 증가함에 따라 수확량이 증가하였다. 청일뽕, 익수뽕과 수원뽕은 모두 식재연차가 증가함에 따라 수확량이 증가하는 경향을 보였으며, 청일뽕은 수령이 증가함에 따라 수확량이 크게 증가하였다. 10a당 오디 수확량은 청일뽕, 과상2호, 수원뽕, 익수뽕 순으로 많았으며, 수령별 수확량은 나무수령이 오래될수록 많았으나, 과상 2호는 어린 나무가 많았다. 오디 판매가격은 전라북도 부안지역이 가장 높았으며, 고창지역이 가장 낮았다. 조사지역의 판매방법별 판매비중은 부안, 고창, 정읍지역은 소비자 직접 판매가 가장 높 았으며, 상주지역의 경우는 대규모 판매상 위탁판매 및 예약판매의 비중이 높아 소비자 직접판매는 상대적으로 낮았다. 판매 방법별 kg당 오디 가격은 소비자 직접판매가 높은 경향을 나타내었으며, 상주지역에서 소비자에게 직접 판매하는 수원뽕의 평균가격이 9,418원으로 가장 높게 나타났으며, 판매 비중은 27.5%로 나타났다. 품종별 오디의 평균판매 가격은 과상2호가 높았고, 다음으로 수원뽕, 익수뽕 순으로 높았으며. 고창지역의 청일뽕 오디가 가장 낮은 가격을 형성하였다. 본 연구에서는 주요 오디 생산지역인 부안, 고창, 정읍과 상주지역의 뽕나무의 수형, 품종, 균핵병 발생 양상, 생산량 및 판매 가격 등을 조사 분석함으로써 향후 자연재해로 인한 피해로부터 농가 소득을 보전할 수 있는 방안으로 재해보험 산정의 기초 자료 등으로 활용이 가능할 것으로 사료된다. Though 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 new income crop. But, a stable production of mulberry was issued on damage by the weather disaster, so it is requires that agricultural disaster insurance import. So, in this study as a basic research for a importation of agricultural disaster insurance, the cultivation of mulberry for the production of mulberry fruits, the shape of tree, the number of a bearing fruit from each cultivar, the occurrence of mulberry fruit sclerotic disease, and a yield and the market price of mulberry fruits were investigated and that results obtained were as follows; The number of mulberry tree each 10a was abundant in Buan and Jeongeup region that cultivated a suitable cultivar on low cut shape, however, a large cultivated Gochang region was little. The number of a bearing fruit per 1m on the branch was highest in the variety of Cheongilppong at Gochang. Yield of mulberry fruits each 10a was Cheongilppong at Gochang, followed by Iksuppong at Sangju. Average sale price of the mulberry fruits was high in the order of Gwasang No. 2, Suwonppong, Iksuppong, and Cheongilppong.
