Peditree

Peditree generates tree-shaped visualizations and computes inbreeding coefficients and coefficients of coancestry from structured variety pedigree databases to analyze genetic relationships and trait transmission in plant breeding.

Key Features:

• Tree-Shaped Representation: Generates tree-shaped representations of pedigree data to display genetic relationships within plant populations.
• Visualization and Lookup Options: Provides multiple visualization and lookup modes to inspect pedigree structures and entries.
• Inbreeding and Coancestry Calculations: Calculates inbreeding coefficients within a single pedigree and coefficients of coancestry among different pedigrees.
• Trait Data Integration: Links trait (phenotypic) data to pedigree records and displays trait-related values within the pedigree representation when available.

Scientific Applications:

• Plant Breeding and Genetics Research: Supports analysis of genetic diversity, relatedness, and breeding history in plant breeding and genetics studies.
• Parental Selection: Assists breeders in selecting parent plants that meet specific genetic criteria using inbreeding and coancestry metrics.
• Trait-Based Line Identification: Enables identification of desirable genetic lines by highlighting pedigree entries that meet specified trait criteria.

Methodology:

Queries a structured database of variety pedigree data and performs recursive analysis to construct a pedigree representation, incorporating genetic and phenotypic information where available.
