Genetic self‐compatibility in a South American species of <i>Ourisia</i> (Scrophulariaceae)

Abstract

Abstract Controlled hand self‐ and cross‐pollination and emasculations were performed on Ourisia poeppigii Benth. (Scrophulariaceae) from the Chilean Patagonia. Ourisia poeppigii is highly self‐compatible and strongly autogamous. No evidence of obligate agamospermy was seen. This first breeding system record for a South American species of the genus Ourisia accords with a report of self‐compatibility provided by Schlessman (1986) for Ourisia macrocarpa Hook. f. ssp. calycina (Col.) Arroyo from New Zealand. However, O. poeppigii is potentially more strongly autogamous than the New Zealand species.
