Potential heterotic groups in hop as determined by AFLP analysis.

Crop Science, September, 2005 by Henning, John A.; Townsend, M. Shaun

Hop (Humulus lupulus L.) is a perennial, dioecious species in which the female inflorescence (cones) are harvested and used in the beer-brewing process to impart bittering and/or flavoring to beer. Hop breeders have typically utilized clonal selection and hybridization to develop new cultivars. The use of genetically diverse parents for the purpose of capturing heterosis in the offspring has received little attention from hop breeders.

The objective of this research was to assign male (N = 80) and female (N = 26) hop genotypes into potential heterotic groups using AFLP-generated molecular ...
