The nomenclatural history of Fritillaria eduardii and the correct names of its varieties

Material of a new fritillary was mentioned in four publications by Eduard Regel in 1884, but he used different names for this material. In the first publication it was named Fritillaria eduardii, but in the following publications the material was described as two varieties of F. imperialis L., both odourless, one with purplish flowers and one with yellow or yellow-red flowers. Both colour varieties, but especially the latter, have been taken into cultivation. Morphological observations and crossing experiments have established that both varieties do not belong to F. imperialis and should be accommodated in F. eduardii. New names for these varieties are proposed, following E. Regel's intention as closely as possibl

Phylogenetic relationships within Fritillaria section Petilium based on AFLP fingerprints

Fritillaria sect. Petilium (Fritillaria L., Liliaceae), consists of four species: F. chitralensis, F. eduardii, F. imperialis and F. raddeana. We studied their phylogenetic relationships with AFLP’s, crossing experiments and morphological observations. The AFLP data confirm that F. eduardii is a separate species and not a variety of F. imperialis. Within F. eduardii the two earlier distinguished varieties can indeed be recognised. Our AFLP results also show that F. chitralensis, originally described as F. imperialis var. chitralensis, is different from F. imperialis and is a species in its own right. The results of the AFLP’s and the crossing experiments show that within F. imperialis two varieties can be recognised, one variety containing representatives that possesses the so called ‘foxy’ smell, and a second variety with odourless representatives. A new name for this odourless variety is propose

Screening for resistance to anthracnose (Colletotrichum gloeosporioides) in Allium cepa and its wild relatives

Colletotrichum gloeosporioides is an airborne disease which causes significant yield losses in shallots (A. cepa var. ascalonicum) grown in the tropics. Breeding for resistance to this disease in shallots has been scarcely carried out and has been primarily focussed on Allium cepa material. Wild species related to shallot might provide sources of resistance and therefore a screening of this material was carried out. Three different isolates of C. gloeosporioides originating from Brazil, Nigeria and Indonesia, were used in the screening procedure. The accessions screened of A. cepa and A. oschaninii were most susceptible to the three isolates. Partial resistance was observed in accessions of A. altaicum, A. fistulosum, A. galanthum, A. pskemense and A. roylei. The highest level of resistance was found in accessions of A. galanthum and A. fistulosum. A. roylei was highly resistant to the Brazilian isolate but very susceptible to the Nigerian and Indonesian isolates. A genetic analysis of the resistance present in A. roylei to the Brazilian isolated revealed that it is dominantly inherited and most probably determined by more than one gene

Identification of Carnation varieties using microsatellite markers

As in many ornamentals, also in carnation the number of varieties in common knowledge is large and identification throughout the chain from breeder to consumer using plant material from different stages and organs may be needed. Results in this study on the use of microsatellite markers from Dianthus caryophyllus L. for the characterization of carnation varieties as well as the construction and evaluation of a molecular database show that these markers show potential for identification purpose
