Beginner Gardening: Yellow Crookneck Squash (bush variety) Question, 1 by Farmerdill

Many of the newer varieties have some resistence to mosaic. It is possible that you have modern version of zucchini which is resistant. That is probably Cucumber mosaic virus which seems attracted to crooknecks and straightnecks. It can be carried on the seeds but is usually transmitted by aphids. Supersett is an example of a resistant crookneck. They still get the disease but are able to fight it off to an appreciable extent.
