...Rosa alba L. also known as the white oil-bearing rose has been cultivated in relatively small areas in Bulgaria during the last century, together with R.damascena. There are no clear historical records on the time of introduction and the origin of the white oil-bearing rose in Bulgaria, but it is considered that the initiation of industrial cultivation of R.alba has probably happened together with R.damascena. The Institute of Roses, Essential and Medical Cultures (IREMC) in Kazanlak, Bulgaria, which is the main supplier of essential oil rose planting material in the country possesses a rich collection of R.alba accessions collected during the last quarter of the 20th century from different rose plantations in the Rose Valley. The oil-bearing R. alba possesses some agricultural advantages over R. damascena, like elevated tolerance to diseases and unfavorable climatic conditions. The composition of essential oil distilled from the ﬂowers of R. alba available in IREMC’s rose collection has already been determined and has been demonstrated to be very similar to that of R. damascena (Nedkov et al., 2009; Dobreva and Kovacheva, 2010; Dobreva and Gerdzhikova, 2013). Since the rose oil distilled from R. alba ﬂowers possesses similar composition to that of R.damascena, in Bulgaria the ﬂowers of R. alba have been traditionally mixed and distilled together with that of R. damascena. However, the ﬂowers of R. alba possess a lower content of rose oil compared to that of R. damascena (Dobreva and Kovacheva, 2010; Kovacheva et al., 2011). This is the main reason the rose growers to cultivate this oil-bearing rose species in small areas in Bulgaria, currently accounting for around 600–1000 decares...
PCA analysis was performed based on the ﬂower biometric data for the 38 analyzed R. alba accessions from IREMC’s genetic resources collection. The obtained PCA plot revealed the existence of two distinct ﬂower pheno groups (Fig.1). The majority of samples, including 31 accessions fell into the group PG:1 [Alba maxima]characterized by higher ﬂower weight, smaller ﬂower diameter, higher number of petals and lower number of anthers (Table1). The other seven accessions characterized by lower ﬂower weight, bigger ﬂower diameter, lower number of petals and higher number of anthers fell into the second group PG:2 [Alba semi-plena]....
As in the case of R. damascena (Rusanov et al., 2005), all analyzed R.alba accessions are clones and originate from a common ancestral genotype together with the well-known European garden rose varieties, R.alba Maxima and R. alba Semiplena. Despite the demonstrated common clonal origin of the analyzed R. alba accessions they differ in the ﬂower phenotype and form two distinct ﬂower phenogroups, PG:1 and PG:2, which ﬁt well to the ﬂower phenotype of R.alba Maxima...and R. alba Semiplena....The micro-satellite analysis also suggests that the accessions possessing one of the observed ﬂower phenotypes, or their clonal ancestors, have derived as a sport from the plants possessing the other phenotype, supporting the view of Thomas (1994) on the origin of R.alba Semiplena as a sport of R. alba Maxima.The genetic base of the observed two ﬂower phenotypes is not clear and could involve changes of expression pattern or functionality of single or small number of genes due to single mutation, transposon jumping and/or epigenetic changes...

‘Alba Maxima’/’Jacobite Rose’/’Double White’/’Cheshire Rose’: Les rosiers Albas – blancs. Parents: Provient probablement d’une mutation de ‘Alba semi-plena’… Les feuilles sont d’un gris-vert, assez clair. La plante vigoureuse émet de forts rejets qui finissent par plier sous le poids des fleurs. Ces rosiers doivent être palissés ou liés autour d’un fort tuteur pour former une belle gerbe de branches souples..
