Incompatibility in plant breeding
Did you know?
WebSexual reproduction in many flowering plants involves self-incompatibility (SIself-incompatibility), which is one of the most important systems to prevent inbreeding. In many species, the self-/nonself-recognition of SI is controlled by a single polymorphic locus, the S-locus. Molecular dissection of the S-locus revealed that SI represents not one system, but … WebHybrid incompatibility is a phenomenon in plants and animals, wherein offspring produced by the mating of two different species or populations have reduced viability and/or are …

WebIn plant breeding procedures, self-incompatibility is an obstacle for breeding pure lines because of the difficulty of obtaining selfed progenies and hybrid plants of two cultivars having the same S-allele. The latter case is a problem in several vegetatively propagating cultivars, such as fruit trees and the sweet potato.

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 …
WebSexual incompatibility may be a serious drawback for further plant improvement programme. Homozygous individuals have low survival value but are extremely useful to conduct basic genetic studies and undertake plant breeding programme. Homozygous individuals can be obtained in several ways.
