“…Interspecific hybridizations have also played an important role in the origin of modern garden roses (Gudin 2000). According to Wylie (1954), the modern garden roses originated from repeated hybridizations among more than ten Rosa species, of which seven made major contributions: R. chinensis Jacq., R. odorata var.…”

Untangling the hybrid origin of the Chinese tea roses: evidence from DNA sequences of single-copy nuclear and chloroplast genes

The tea-scented China roses largely correspond to the three recognized double-petaled Rosa odorata (Andrews) Sweet (Rosoideae, Rosaceae) varieties, which are the ancestors of modern hybrid tea roses and had a definite and permanent influence on the evolution of modern garden roses. Here the hypothesis of a hybrid origin of the tea-scented China roses between R. odorata var. gigantea and R. chinensis was tested. Two single-copy nuclear genes of the cytosolic glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and the chloroplast-expressed glutamine synthetase (ncpGS) together with two plastid loci (trnL-F and psbA-trnH) were sequenced for representative accessions of four R. odorata varieties, R. chinensis, and 28 other Rosa species. Phylogenetic relationships were estimated from two nuclear loci using maximum parsimony and Bayesian analyses, and a haplotype network was constructed on the combined plastid data using NETWORK. For GAPDH and ncpGS loci, the clonal sequences of the three double-petaled varieties were clustered into two clades, one clade with R. odorata var. gigantea, and the other with partial sequences of R. chinensis, which suggested that the tea-scented China roses were hybrids between R. odorata var. gigantea and R. chinensis. Two plastid loci suggested that R. odorata var. gigantea could be the maternal parent and R. chinensis the paternal parent.

The role of plant growth promoting rhizobacteria for growth and rooting in Rosa damascena Mill. cuttings was evaluated in this study. Fifteen distinctive and fast growing rhizobacterial colonies (strains) were chosen to inoculate the Rosa cuttings by dipping in them. Growth parameters like shoot length, new shoot fresh weight, new shoot dry weight, root length, root fresh weight and root dry weight showed highly significant results while mortality percentage of cutting was non-significant. Results of the pot experiments revealed that most of the isolates showed growth promoting activities in Rosa cuttings except the isolates B5 which was proved to be growth limiting strain as it gave 20-40% less result for all parameters. The most prominent results were produced by isolated strains F6 (Pseudomonas fluorescens), LSI19 (Rhizobium leguminosarum) and LC4 (Vibrios vulnificus). Isolate LSI19 showed maximum shoot length, new shoot fresh and dry weights with an increase (over un-inoculated control) of 51.6%, 55.2% and 48.0%, respectively. Root growth was positively influenced by isolate F6 with maximum root length and root fresh and dry weights (173.0%, 68.7% and 124.7%, respectively). All the other strains enhanced cutting growth characters up to 30-60% compared to control. Strains LSI19, F6 and LC4 were proved to be superior strains in all growth attributes. Results on the bases of total score obtained by each strain in all growth parameters showed that strains LSI19, F6 and LC4 got first three positions. Therefore, these three strains (LSI19, F6 and LC4) were selected for further studies.
