Focus of the Genetic Diversity module

Characterizing the genetic basis of variation in plants and linking to observable traits will provide an important framework for understanding population structure, evolutionary patterns, and could potentially significantly increase the efficiency of selections made in plant breeding programs. The Genetic Diversity module specializes in storage of genotypes, phenotypes and their environments, germplasm, and association data. We implement the Genomic Diversity and Phenotype Data Model (GDPDM) database schema, which efficiently stores anything from small-scale SSR diversity studies to large-scale SNP/indel-based genotype-phenotype studies with billions of allele calls.
