How can natural hybridisation between self-compatible and self-incompatible species be bidirectional?

C Li, RD Cousens, MB Mesgaran

Journal article  |  2019  |  WEED RESEARCH

Self-compatible (SC) plants often deposit pollen on their own stigmas before flowers open. Thus, if we find natural hybrids betwee..
