Abstract:
Within Rosa section Caninae (dogroses) two different growth types exist, arching (L-type) and erect (D-type). Due to the specific mode of chromosome allocation during meiosis, character inheritance in dogroses is maternally skewed. In this paper we try to assess the mode of inheritance of the 'growth form' in reciprocal hybrids of R. canina L. and R. rubiginosa L. to predict possible ecological niches and radiation processes of hybridogenic offspring. A quantitative analysis of mechanical properties indicates that neither an expected parentally skewed nor an intermediate habit was expressed by the hybrids, but a dominant L-type as in R. canina, regardless of the parental relationship (pollen-parent or seed-parent). Our results implicate two possible scenarios to be further tested: (a) R. canina acts as a species with a dominant allele for the growth form character. If so, this would be the first evidence of a Mendelian character inheritance in the dogroses. (b) 'Growth form' in the dogroses is not a Mendelian character, but a syndrom which realises as an emergent functional property with underlying phenotypic structural differences in stem and wood anatomy.
