2009 journal article

Crossability, cytogenetics, and reproductive pathways in Rudbeckia subgenus Rudbeckia

HortScience, 44(1), 44–48.

By: I. Palmer*, T. Ranney*, N. Lynch* & R. Bir*

author keywords: apomixis; coneflower; cytology; DNA content; flow cytometry; relative genome size; plant breeding; polyploidy; pseudogamy
TL;DR: Although most taxa had low self-fertility, seedlings (with genomic sizes similar to their maternal parent) resulted after interspecific crosspollination, indicating that pseudogamy is one reproductive pathway in Rudbeckia species. (via Semantic Scholar)
