Si-Yong Kang,Sang Hoon Kim,Wook-Jin Kim,Geung-Joo Lee,Hi-Sup Song,Dong Sub Kim,Jin-Baek Kim 한국원예학회 2009 Horticulture, Environment, and Biotechnology Vol.50 No.6
Genetic diversity and relationship of Hibiscus syriacus L. were analyzed using 127 cultivars and 7 landraces by the amplified fragment length polymorphism (AFLP) and the assessment of morphological characteristics. The AFLP analysis was carried out by using capillary electrophoresis with 28 fluorescent labeled primer combinations. Morphological evaluation was executed by the 11 parameters. A multivariate data analysis was performed using similarity coefficients, Euclidean distance, unweight pair group method with arithmetic averages (UPGMA) clustering method, and principal coordinate analysis (PCoA) of NTSYS-pc program. In the AFLP analysis, a total of 2, 842 bands were produced in the 28 primer sets, and 43.4% (1,236 bands) of them were identified to be polymorphic. Similarity coefficient values ranged between 0.49 and 0.98. Scattered distribution of the 127 cultivars and 7 landraces was identified, and they were divided into three major groups based on PCoA and UPGMA clustering analysis. In the morphological evaluation, Euclidean distance values ranged from 0.28 to 10.32. The distribution showed that there was a little difference compared with the result of AFLP. The pedigrees of several cultivars were cross-correlated using the results of AFLP and morphological analysis.
Evaluation of Root Characters Associated with Lodging Tolerance by Seedling Test in Rice
Si-Yong Kang,Won-Ha Yang,Hyun-Tak Shin 韓國作物學會 1999 Korean journal of crop science Vol.44 No.4
Rice seedling test was conducted to check the loging tolerance at ripening stage through evaluating the root characters. Thirteen Korean and foreign rice cultivars with direct seeding adaptable or high quality characteristics were grown in a cell pot and under submerged paddy. The root characters and pushing resistance of rice hill were determined at seedling and ripening stage, respectively. The diameter of crown root at the 7th and 8th leaf stages was thicker in lodging tolerance cultivars than those of others and showed significant-positive correlation with both pushing resistance and crown root diameter of mature plants. Also, the tensile strength of crown root at the 7th and 8th leaf stage showed highly positive correlation with the tensile strength of crown root of mature plants. The number of crown root at 7th leaf stage was significant-positively correlated with that of mature plant. The diameter of seminal root was not significantly correlated with the diameter of crown root throughout the whole growth stage. These results indicate that the diameter, tensile strength and number of crown root associated with root lodging tolerance can be detected with the seedling at about 7th or 8th leaf stage, and the seedling test using the cell pot is an useful and practical method to select lodging tolerant cultivars or lines of rice based on root characters, especially diameter of crown root.
Comparative Analysis of Root and Shoot Growth between Tongil and Japonica Type Rice
Si-Yong Kang,Shigenori Morita 韓國作物學會 1998 Korean journal of crop science Vol.43 No.3
Root and shoot development of two rice (Oryza sativa L.) cultivars with different genetic backgrounds was studied with reference to their relative growth. Tongil type (indica-japonica hybrid) cultivar 'Kuemkangbyeo' and japonica cultivar 'Koshihikari' were grown in 5000-1 a Wagnar pots under flooded condition. Three plants with roots of both cultivars were taken in every phyllochron through the heading stage to record morphological characteristics of shoot and root system. Compared to Koshihikari, Kuemkangbyeo produced more tillers and had greater shoot weight and leaf area per hill. Length and weight of the root system in both cultivars increased exponentially with time. At the same time, root system development was significantly faster in Kuemkangbyeo than in Koshihikari after the panicle initiation stage. As a result, Kuemkangbyeo has a vigorous root system which consists of larger number of nodal roots compared to Koshihikari. Also, the root length and weight per unit leaf area of Kuemkangbyeo were larger than those of Koshihikari in the later half of growing period, which suggests possible higher physiological activity of the root system of Kuemkangbyeo which is known as a high-yielding cultivar. The relationship between root traits (crown root number, total root length, and root dry weight) and shoot traits (leaf area and leaf+culm dry weight) in both cultivars closely showed allometry until the flag leaf stage.
