Male sterility in Hydrangea

Hydrangea L.

A genetic feature of Hydrangea related to alloplasmic male sterility and the transformation of stamens into petaloid structures, used primarily in breeding to obtain double-flowered forms.

In the reference 37 varieties crop Hydrangea, where this is mentioned in the description.

Male sterility in Hydrangea manifests through morphological changes, such as the conversion of stamens into petaloid or stigmatoid structures. This phenomenon is frequently observed in interspecific hybrids and serves as a breeding tool in the development of ornamental double-flowered cultivars.

To assess pollen fertility, methods involving the analysis of grain viability and morphology are applied, as well as the study of meiosis in microspore cells. The data obtained are used to determine the compatibility of parental pairs; however, standardized agronomic scales for evaluating sterility are absent in production practice.

General information about the subject — on the page Cytoplasmic Male Sterility (CMS).
