In this study we established the high throughput screening system of high functional soybean cultivars using PLS modeling from FT-IR spectral data of soybean(Glycine max L) seeds. Crude extract of 20% methanol from soybean seed powders (153 lines) were used for FT-IR spectroscopy. Total fatty acid, carotenoids, flavonoids and phenolic compounds contents from soybean seed powders were analyzed using UV-spectrum and GC analysis respectively. PCA analysis showed that 153 soybean lines formed a single clusters with a few outlier. PC score 1 and 2 represented 39.5, 16.4% of total variation, respectively. And than showed change patten from the middle to outside for PCA plot. We conducted PLS regression analysis between FT-IR spectral data and fatty acids data. Palmitic acid showed the highest regression coefficient (R=0.78). This result implied that the content of palmitic acid could be predicted from FT-IR spectral data from soybean seed powders with relatively high fidelity. PLS modeling of total carotenoids also showed regression coefficient of 0.69. Regression coefficient of total flavnoids and phenolic compounds were 0.44, 0.39, respectively. At present, we are trying to confirm the accuracy of PLS prediction modeling using targeted metabolite analysis (GC-MS, LC-MS) from predicted soybean lines. To increase the accuracy of PLS modeling, we also trying to standardization of spectroscopy and spectral data processing. Furthermore we are going to develop PLS modeling from GC-MS, LC-MS data. The PLS prediction modeling established in this study could be applied for high throughput screening of other leguminous plant.

A new standard rose cultivar ‘Pink Stone’ was bred from the cross between red standard cultivar ‘Red Queen’ and pink standard cultivar ‘Vivaldi’ at the National Horticulture Research Institute. The cross was made in 2001 and ‘Pink Stone’ was finally selected in 2006 after investigating characteristics for three years from 2003 to 2006. ‘Pink Stone’, a deep pink standard cultivar grows vigorously and has powder mildew resistant. The major characteristics of this cultivar are 115.1 stems/m2/year in yield, 77.7 cm in length of cut flower, 10.5 cm in flower diameter, 67.0 in petal number, and 12.0 days in vase life. This cultivar can be propagated by both cutting and grafting. The consumer’s preference of this cultivar is relatively higher than that of control cultivar, ‘Noblesse’.
