An Evaluation of Pickling Cucumber Varieties at Isabela Substation

Abstract

1. Eleven pickling cucumber varieties were planted together with P.R. 39 at Isabela, P.R., on August 25, 1960. 2. The most serious disease encountered was downy mildew. 3. P.R. 39 yielded more than twice as much as Wisconsin SMR 15, the next variety in rank. 4. This yielding superiority of P.R. 39 over the other varieties is attributed to its resistance to downy mildew.
