Inbreeding depression in plant breeding

WebThis is known as inbreeding depression. INBREEDING DEPRESSION Plant and animal breeders try to improve their race with respect to certain traits by using the "best" individuals in each generation. Breeders also want homogeneity; they try to achieve this by systematic inbreeding, which increases homozygosity. Webing depression. This is due in large part to the seminal but controversial work of Lande and Schemske (1985) and Schemske and Lande ( 1985). They postulated a direct link between levels of inbreeding depression and the evolution of self-fertilization, providing a rationale for measuring levels of inbreeding depression in plants.
