THE EVOLUTION OF CARNATION VARIETIES THAT HAVE BEEN GRANTED PROTECTION IN FRANCE OVER THE LAST FIFTEEN YEARS
Since French Protection of Plant Breeders' Rights was first set up, a total of 450 different varieties of carnations have been forwarded to the French inspection service (G.E.V.E.S.) in the period from 1972 to 1986. Over the years, things have evolved a great deal. From 1980 onwards, mutant varieties of the SIM type were replaced by a wide range of hybrids which in turn went on to engender other varieties, also created through mutation. The number of varieties of spray carnations has increased constantly and in 1983 Italian varieties of the dwarf flowered type began to appear. The fact that Protection has been discontinued in a total of 45% of these varieties seems to be due primarily to their vulnerability to Fusarium oxysporum, which has caused their cultivation to become a highly risky proposition in the Mediterranean region.
