Induced Variation in Tetraploid Rudbeckia subtomentosa ‘Henry Eilers’ Regenerated from Gamma-irradiated Callus

Oates, K. M., Touchell, D. H., & Ranney, T. G. (2013, July 1). HortScience.

By: K. Oates n, D. Touchell n & T. Ranney n 

author keywords: Asteraceae; autotetraploid; black-eyed Susan; coneflower; induced mutation; plant breeding
topics (OpenAlex): Plant Pathogens and Resistance; Plant Genetic and Mutation Studies; Plant tissue culture and regeneration
TL;DR: Investigating the effect of gamma radiation dose on in vitro survival and development, and ex vitro fertility, phenology, and morphology of tetraploid Rudbeckia subtomentosa ‘Henry Eilers’ found flower morphology, flower number, and plant overwintering survival were often negatively affected with increasing radiation dose.

Influence of Induced Polyploidy on Fertility and Morphology of Rudbeckia Species and Hybrids

Oates, K. M., Ranney, T. G., & Touchell, D. H. (2012, September 1). HortScience, Vol. 47, pp. 1217–1221.

author keywords: Asteraceae; autotetraploid; allotetraploid; blackeyed Susan; chromosome doubling; coneflower; whole genome duplication; plant breeding
topics (OpenAlex): Plant Pathogens and Resistance; Plant tissue culture and regeneration; Powdery Mildew Fungal Diseases
TL;DR: Fertility, morphology, phenology of flowering, and perennialness (overwintering survival) for lines of diploid and induced allotetraploids of R. subtomentosa 'Henry Eilers' were evaluated and some polyploidy lines varied significantly in certain morpholog- ical traits. (via Semantic Scholar)
