When cucumber was inoculated with ZYMV at transplanting time, 15, 30, 45, 60, and 75 das after transplanting, vine length, internode length, number of leaf of the plants and marketable ield largel decreased as the cucumber infected earlier. The regression models were obtained between the disease incidence levels at 20 das after transplanting as the inoculation degrees and the marketable ield of cucumber: = 9333.1e 0.0317x (R 2 = 0.8946) at the semi-forcing culture and = 14695e 0.0303x (R 2 = 0.8735) at the retarding culture. And the cucumber ield loss regression models between the smptoms incidence das from the final harvesting time and the rates of ield decrease were expressed as =1.0851x 6.7067 (R 2 = 0.9567) at the semi-forcing culture and=1.0439x + 2.1321 (R 2 = 0.9674) at the retarding culture.
