摘要： Estimates of proportions of parental contribution to germplasm populations are useful to breeders. The objective of this research was to assess the ability of amplified fragment-length polymorphism (AFLP) markers to characterize the contributions of the original parents to later cycles of a soybean [Glycine max (L.) Merr.] population that had undergone recurrent selection, Use of four primer pairs yielded a total of 47 polymorphic bands, Estimates of parental contribution were consistent between primer pairs and between cycles and conformed to those expected based on pedigrees. Standard errors of estimates were 3 to 5%, indicating satisfactory precision. The AFLP markers should provide relatively inexpensive, precise estimates of parental contribution. This marker system may also be useful in tracking genetic changes in populations.
