A Fifth Gene for Male Sterility in Cucumis melo
Cucurbit Genetics Cooperative Report 13:34-35 (article 13) 1990 M. Lecouviour Clause Semences Professionnelles, Mas St Pierre, F-13210 St Rémy, France M. Pitrat and G. Risser INRA, Station d’Amélioration des Plantes, BP 94, F-84143 Montfavet Cedex, France Four genes of male sterility have been described in muskmelon (1,2,3,4). A fifth gene has been observed and used […]
Controversy on Resistance to Fusarium Wilt in ‘Perlita’ (Cucumis melo L.)
Cucurbit Genetics Cooperative Report 10:60-61 (article 32) 1987 G. Risser Institut National de la Recherche Agronomique 84140 Avignon-Montfavet, France In 1985, Zink and Gubler (3) reported that ‘Perlita’ resistance to Fusarium wilt (Fusarium oxysporum f. sp. melonis) races 0 and 2 is conferred by a dominant gene Fom-3 different from the gene Fom-1 that controls […]
Maternal Effect on Growth of Melon Seedlings
Cucurbit Genetics Cooperative Report 9:68-69 (article 21) 1986 G. Risser INRA, Station d’Amelioration des Plantes Maraicheres, 84140 Montfavet, France Seed size varies considerably in melon (Cucumis melo L.). Weight of 100 seeds varies from less than 0.5 g to more than 7 g. This seed size variation influences seedling size and is very troublesome in […]
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 […]
Varietal Differences in Growth of Melon (Cucumis melo L.) at Low Temperature
Cucurbit Genetics Cooperative Report 2:23 (article 14) 1979 G. Risser Station d’Amélioration des Plantes Maraîchères, I.N.R.A. Domaine Saint Maurice, 84140 Montfavet-Avignon, France Melon is known as requiring high temperatures for a good growth, but we did not know differences in varietal reaction occur at low temperature. First, we studied the action of root temperature. For […]
