Incompatibility in plant breeding pdf
WebSelf-incompatibility or intraspecific incompatibility is a well-designed genetic mechanism by which certain plants recognize and reject their own pollen thus forcing outbreeding. It is … WebSelf-incompatibility (SI) refers to all genetic mechanisms in flowering plants that prevent self-fertilization through the recognition and rejection of self-pollen by the style of a flower ( DeNettancourt, 1977 ). SI is generally classified into two types: heteromorphic and homomorphic SI.
