Mixtures of different cucumber cultivars or breeding lines (collectively called cultigens) has been used commercially in some parts of the U.S. The objective of this study was to determine whether mixtures of cultigens produce higher yields than pure stands. Three cultigen pairs: Gy 14A+ M 21, Gy 4 + WI 2757 and Regal+ Carolina (higher yielding cultigen listed first) were blended at 0, 25, 50, 75 and 100%, and sown in a spring and summer planting in 1989. Fruit were harvested 6 times in each study and graded according to N. C. standards. Data were collected on yield, earliness, vine size, sex expression and disease resistance. Yields from the spring planting were superior to those from the summer, For maximum fruit weight (Mg/ha), a mixture consisting of 25% of the lower yielding cultigen of each pair should be grown. However, for maximum fruit value ($/ha), the higher yielding cultigen of each pair should be grown in pure stand. We concluded that arbitrary mixtures of cultivars offer no advantage in most cases, although superior mixtures might be produced by evaluating cultigen pairs for complementation.
