Incompatibility in plant breeding
WebNov 29, 2024 · Self-incompatibility affects not only the formation of seeds, but also the evolution of species diversity. A robust understanding of the molecular mechanisms of self-incompatibility is essential for breeding efforts, as well as conservation biology research. In recent years, phenotypic and multiple … 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.

WebSexual reproduction in many flowering plants involves self-incompatibility (SI), 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.
