When typhoon occurs, the meteorological conditions get worse and can cause a large damage from storm and flood . This damage, however, can be minimized if a precise analysis of the runoff characteristics by typhoon tracks is used in the flood contorl This paper aims at the analysis of storm occurrence and runoff characteristics by typhoon tracks in Nakdong river basin. Therefore, the data of 14 typhoons which invaded Nakdong river basin during the period from 1975 to 1991 were collected, analyzed, and studied. The major results of this study are as followings; 1) The frequency of the typhoon occurrence here in Korea was affected by the storms three times a year on the average. The highest-recorded frequency was during the months of July to September. 2) The survey of the track characteristics depending on the forms of the storm in the Nakdong river basin showed that typhoon storm advanced from the south of the basin to the north, while the frontal type storm was most likely to advanced from the west to the north. 3) Typhoon tracks are classified into three categories, 6 predictors with high correlation coefficient are finally selected, and stepwise multiple regression method are used to establish typhoon strom forecasting models. 4) The riview on the directions of progress of the storm made it clear that the storm moving downstream from upstream of the basin could develop into peak discharge for ca short time and lead to more flood damage than in any other direction.

Morphological classification and molecular marker development of white clover (Trifolium repens L.) parents and hybrids

한승섭,Sun Hyeon-Jin,은창호,이효연 한국식물생명공학회 2022 Plant biotechnology reports Vol.16 No.6

White clover (Trifolium repens L.) is a perennial legume with various traits; it grows in temperate regions and has high potential as an ornamental plant. In the present study, four parental varieties (Ladino, Green Ice, William, and Dragon’s Blood) of white clover were classifed based on 11 morphological traits [plant form, leaf shape, leaf edge shape, upper lamina color, lower lamina color, white V mark, midrib color, leaf patterns (front and back), fower color, and peduncle color]. Based on these traits, two hybrids were selected as follows: Ladino×Green Ice [hereafter referred to as Jeju Hapiness-1 (JH-1)] and William×Dragon’s Blood (JH-5). In addition, random amplifed polymorphic DNA (RAPD) analysis was performed to confrm the molecular biological relationship between the parental varieties and hybrids. We confrmed to contain the polymorphic bands of the parental varieties at OPC13, OPD6, and OPG4 operon primers from JH-1, and at OPE10, OPG12, and OPH11 from JH-5. Further, the RAPD patterns from the hybrids were compared with the four parental varieties. A distinguishable RAPD pattern was identifed in OPC13 and OPG4 from JH-1 and in OPG12 and OPH11 from JH-5. In addition, polymorphic DNA fragments in which the genetic relationship between the parental varieties and hybrids was confrmed were converted into sequence characterized amplifed region (SCAR) markers. The morphological classifcation criteria, RAPD pattern, and SCAR marker are all considered useful for the classifcation and breeding of white clover and protecting varieties developed.

In this study, zoysiagrasses found in a major province of the Korean peninsula were collected and identified by molecular techniques. The zoysiagrasses used in this study were collected from mountainous national parks; ‘oreum’ areas; and from inland, coastal and island areas, including marine and coastal national parks on the west, east, and south coasts. Molecular identification was done by means of a cleaved amplified polymorphic sequence (CAPS) marker analysis based on the nrDNA-internal transcribed spacer (ITS) method established by our research team. Additionally, in this study the ITS-based TaqMan single-nucleotide polymorphism (SNP) genotyping assay was developed and used to perform molecular identification more rapidly and accurately. In total, 450 collected zoysiagrass plants were classified into three lines (234 Zoysia japonica plants, 62 Zoysia sinica plants, and 154 Z. japonica and Z. sinica hybrid plants) by molecular identification based on the ITS-based CAPS marker analysis and ITS-based TaqMan SNP genotyping assays. The results of the ITS-based TaqMan SNP genotyping assay were consistent with those of the ITS-based CAPS marker analysis. Both the ITS-based CAPS marker analysis and the ITS-based TaqMan SNP genotyping assay were found to be efficient molecular methods to identify the three species of zoysiagrasses. Specifically, the ITS-based TaqMan SNP genotyping assay method developed inthis study produced results more rapidly compared to the ITS-based CAPS marker analysis method. The habitat distributions of each of the molecularly identified zoysiagrass plants investigated in this study were also assessed. The Z. japonica plants were mainly distributed in mountainous national parks and oreum areas as well as inland and coastal areas. The Z. sinica plants were distributed along the coast and on rocks and stones frequently submerged in seawater. The Z. japonica and Z. sinica hybrid plants were distributed more in the inland, coastal, and island areas than in the mountainous national parks and oreum areas. Findings related to the leaf blade width as a main external morphological classification characteristic of the molecularly identified 450 zoysiagrass plants are described below. The leaf blade width ranged from 4 to 5 mm for the Z. japonica plants, from 2 to 4 mm for the Z. sinica plants, and from 3 to 4 mm for the Z. japonica and Z. sinica hybrid plants. Additionally, some Z. japonica and Z. sinica plants and Z. japonica and Z. sinica hybrid plants with leaf blade widths of 2 to 3, 4 to 5, and from 2 to 3 and 4 to 5 mm, respectively, were also present. Because the ranges of the leaf blade width of each species overlapped, it was difficult to identify the hybrid lines using this metric. The feasibility of the developed molecular identification method for these three species of zoysiagrasses was confirmed in this study 본 연구에서는 한국의 국립공원(산) 및 오름, 서해안 및 동해안, 남해안 부근의 해상국립공원을 포함한 해안 및 섬 등에서 한국잔디류 620점을 수집하였다. 이식, 보존 및 증식 중인 다량의 잔디 450개체는 분자생물학적 분류동정을 수행하였으며, 들잔디(Zj) 234개체, 갯잔디(Zs) 62개체, 들잔디와 갯잔디의 교잡종(H) 154개체로 식별되었다. 본 연구에서 종의 분류 동정 결과는 새로 개발된 ITS 기반 TaqMan SNP genotyping assay 분석과 기존 방법인 ITS 기반 CAPS 분석에서 그 결과가 일치하였으며, ITS 기반의 TaqMan SNP genotyping assay 분석법은 ITS 기반 CAPS 마커 분석법보다 더 신속하게 종 식별 가능함이확인되었다. 분류 동정된 450개체의 들잔디, 갯잔디, 교잡종의 서식환경별 분포를 조사한 결과, 들잔디의 경우 주로 국립공원(산) 및 오름, 내륙, 해안가 등에 분포되었고, 갯잔디의 경우 바닷물에 자주 잠기는 바위나 돌, 해안가의 바닷물이 인접한 부근에서 분포되었으며, 들잔디와 갯잔디의 교잡종은 국립공원 산 및 오름보다 내륙 및 해안가, 섬지역에 걸쳐 다양한 장소에 분포되었다. 기존 외부형태학적으로 주요한 분류 동정의 형질인 잎의 너비(엽폭)가 들잔디와 갯잔디 교잡종의 분류동정에 이용할 수 있는지 분자생물학적으로 분류 동정된 450 개체의 한국잔디류의 주요 외부형태적 분류 특성인 엽폭을 조사한 결과, 엽폭의 크기는대체로 들잔디 4–5mm, 갯잔디 2–4mm, 들잔디와 갯잔디의 교잡종 3–4mm로 분석되었다. 일부 엽폭 크기는 들잔디(2– 3mm)와 갯잔디(4–5mm), 들잔디와 갯잔디의 교잡종(2–3mm과 4–5mm)으로 확인되어 엽폭 크기에 의하여 교잡종을 확실히 분류 동정하기에 쉽지 않았기 때문에 본 연구에서 개발된 신속정확한 분자생물학적 분류 동정법의 필요성을 재확인하였다.
