SurvivorSelectionOperator

class pybrops.breed.op.ssel.SurvivorSelectionOperator.SurvivorSelectionOperator

Bases: object

Abstract class defining interfaces for survivor selection within an entire breeding program.

The purpose of this abstract class is to provide functionality for:

1. Survivor selection for an entire breeding program.

Methods

sselect

Select progeny survivors in a breeding program.

abstract sselect(genome, geno, pheno, bval, gmod, t_cur, t_max, miscout, **kwargs)

Select progeny survivors in a breeding program.

Parameters:

• genome (dict) – Dictionary of genomes for the breeding program.

• geno (dict) – Dictionary of genotypes for the breeding program.

• pheno (dict) – Dictionary of phenotypes for the breeding program.

• bval (dict) – Dictionary of breeding values for the breeding program.

• gmod (dict) – Dictionary of genomic models for the breeding program.

• t_cur (int) – Current time in the breeding program.

• t_max (int) – Deadline time for the breeding program.

• miscout (dict, None) – Pointer to a dictionary for miscellaneous user defined output. If dict, write to dict (may overwrite previously defined fields). If None, user defined output is not calculated or stored.

• kwargs (dict) – Additional keyword arguments.

Returns:

out – A tuple of length 5: (genome, geno, pheno, bval, gmod)

Where:

• genome is a dict of genomes for the breeding program.

• geno is a dict of genotypes for the breeding program.

• pheno is a dict of phenotypes for the breeding program.

• bval is a dict of breeding values for the breeding program.

• gmod is a dict of genomic models for the breeding program.

Return type:

tuple
