Building Pedigree Table Recursively — build_pedigree

Recursively builds a pedigree table by extracting and tracking parents for each genotype/germplasm in the provided list. The function handles backcross cases and updates the pedigree data frame with parent information for multiple generations.

Usage

build_pedigree_table(
  geno_list = NULL,
  pedigree_list = NULL,
  pedigree_df = NULL
)

Arguments

geno_list: A character vector of genotype/germplasm names.
pedigree_list: A character vector of associated pedigree strings, corresponding to the genotypes in geno_list.
pedigree_df: A data frame of pedigrees from a previous iteration, used to accumulate pedigree data. If NULL, a new data frame is created.

Value

A data frame with three columns: - `Variety`: The identifier for the individual genotype. - `Female`: The identifier for the female parent. - `Male`: The identifier for the male parent. The pedigree is built recursively, with individuals listed before any appearance as a parent.
