RESISTANCE OF CHINESE VITIS SPECIES TO ELSINOE-AMPELINA (DE-BARY) SHEAR

Resistance to grape anthracnose [Elsino ampelina (de Bary) Shear] was evaluated in 13 known Vitis species and five taxonomically undescribed grapes native to China. One hundred and eight clones of Chinese Vitis species were tested under field conditions between 1990 and 1992. Ber ry infection did not occur in these species. Leaves displayed strong r esistance to anthracnose, although intraspecific variations were obser ved. There was no relationship between anthracnose resistance and geog raphical origin of the species. Results from this study indicate that oriental grape species are useful for disease-resistance breeding.
