Vat and Fn, Two Linked Genes in Muskmelon
Cucurbit Genetics Cooperative Report 5:29-30 (article 15) 1982 M. Pitrat1, H. Lecoq2 and G. Risser1 I.N.R.A., B.P. 94, 84140 Montfavet-Avignon, France Many viruses affecting melon are non-persistently aphid transmitted. Cucumber mosaic virus (CMV) is probably the most widespread, but Watermelon mosaic 1 and 2 (WMV-1 and WMV-2), and in France a third potyvirus tentatively named […]
Effect of Ethylene on Fruit Set in Emasculated and Non-emasculated Flowers of Muskmelon
Cucurbit Genetics Cooperative Report 5:33-34 (article 17) 1982 C. D. Zack and J. B. Loy University of New Hampshire, Durham, NH 03824 Studies by Mann (1) indicated that injury to the flower during emasculation inhibited fruit set.

Loy University of New Hampshire, Durham, N.H. 03824 The bush phenotype facilitates conventional row culture and manageability of winter squash, however, there is little information regarding comparative photosynthgetic efficiency and productivity between bush and vine forms of C. maxima. In 1980 and […]
Update of Cucurbit Gene List and Nomenclature Rules
Cucurbit Genetics Cooperative Report 5:62-66 (article 29) 1982 In order to prevent confusion when genes of one species are transferred to another species, it is recommended that the same symbol not be used for different genes of compatible species. Interspecific crosses are being increasingly used, particularly in squash breeding programs. Therefore, the Cucurbit Gene List […]
