- Watermelon lines with gummy stem blight resistance for crossing with the most advanced lines in our progeny selection program.
T. P. M. den Nijs
- In research for resistance to several cucumber diseases (notably Cucumber Green MOttle Mosaic virus, black root rot caused by Phomopsis sclerotoides, and rootknot nematodes) the Institute for Horticultural Plant Breeding has started a program of interspecific hybridization in Cucumis. Despite vigorous acquisition efforts the available Asiatic wild and feral material remains scanty. These accessions deserve much evaluation because less severe hybridization problems are to be expected. Therefore, we request any wild or feral cucumber material of Asiatic origin, including the Turkey-Lebanon area. Screening data, identification, somatic chromosome number and crossing behavior will be supplied.

Stocks for Exchange
W. P. Bemis
- Cucurbita foetidissima, Buffalo gourd, Arizona Hybrid #1 (158 x 142). This hybrid seed has been produced utilizing the gynoecious character segregating in experimental lines of C. foetidissima. It represents a relatively homogeneous seed source when compared to composites of wild collections.
J. M. Crall
- Watermelon lines with large fruit size, combined resistance to wilt and anthracnose, intense red flesh color, and high soluble solids juice; also we could furnish small samples of seed of our mosaic-tolerant lines.
