Selecting a core germplasm population using molecular markers: a case study with Eucalyptus pellita grown in common garden trials.

ABSTRACT: Germplasm resources are crucial for revitalizing of the forest industry and plant breeding. Eucalyptus pellita is one of the most widely planted tropical eucalyptus species used for pulp and timber production. Maintaining large field-based germplasm collections for breeding and conservation is expensive. A smaller "core" population, retaining most of genetic diversity, is an efficient strategy. A comparative analysis using the marker-based tools DARwin, CoreFinder, and Core Hunter identified hypothetical subpopulations from 10 to 15% of the source population size, while still capturing the majority of the broader population diversity. Examination of phenotypic data in the source and hypothetical core populations over 34 months allowed comparison of growth and survival, and the effects of m
