Looked at the SSE 2003 catalog and see also see lots more warty squash. But as I recall, the yellow crookneck was more warty half century ago than it is now - and today's version also gets wartier late in the season. Blue Hubbard has always been warty. Likewise Turks turban but less than blue Hubbard. Do you suppose the maybe warts had been bred out and the squash are now reverting (evolutionary regression?) due to the emphasis on saving seeds. Seems that enforced self-pollination may have such a result. Not that I have any experience with this - at least not with respect to warty squash. Google search indicates some warts are caused by mosaic diseases. Olin ----- Original Message ----- From: "Margaret Lauterbach" > What's the evolutionary advantage for warty squash?
