Interpretive Summary:

Technical Abstract: Most Korean vineyards employed spur-pruning type modified-T trellis system. This produce system is suitable to spur-pruning type cultivars. But most European table grape is not adaptable to this produce system because their fruitfulness is sufficient to cane-pruning type system. Total 20 of fruit characters evaluated for finding spur-pruning type germplasm in grape germplasm in NCGR Davis. Total 81 of germplasm identified the spur-pruning type grape cultivars, and their origins are in four different regions (Middle East Asia, East Asia, Europe, and America). In the MVA result, Middle East Asia, Europe, and America were shown same fruit characters. However, East Asia cultivars, such as Campbell Early and Kyoho, had significant differences of berry detachment to Europe or Middle East Asia germplasm. Total 49 of germplasm compared fruit phenotype with shoot phenotypes from NCGR Davis data. The Middle East Asia, Europe, and America cultivars are statistically different to East Asia in OPLS-DA. Shoot color, shoot tip color, and shoot tip anthocyanin were related to the difference between East Asia germplasm and the other origins.
