The Pedigree Data Management Module supports the plant breeding needs of many types of crops. In addition to self-fertilizing crops, this module also supports clonal crops, crops with cytoplasmic male sterility, cross-pollinating crops, open-pollinated crops, and polycrosses and synthetics common to some grass breeding programs.
The main features are:
A “germplasm” management system where you can define and use traits specific to your crop or breeding program for your parents and populations. Many tools help you to sort, report, group, and perform many other functions with your genetic material.
Multi-trait selection indices (weighted or non-weighted, optional truncation) for parents or populations. Instantly count and view all crosses involving each parent, or a group of parents, in your entire breeding system.
Cross prediction among homozygous self-fertilizing parents for traits where additive genetic variance is most important.
Make crosses among rows or populations of parents, with options for pedigree writing nomenclature.
Make crosses or many other breeding events within a nursery or greenhouse typically where individual plants must be identified in up to 19 (currently) breeding methods, including: selfed selection, selfed bulk, open pollinated selection, open pollinated bulk, bulk cross, sterilization cross, sterilization backcross, emasculated cross, genetic male sterile maintainer cross, genetic sterile backcross, genetic sterile cross, full-sib selection, full-sib bulk, half-sib selection, half-sib bulk, seed increase, regular cross, regular backcross, doubled-haploid.
Many options for specifying text strings for pedigree or selection history updates for all methods, as well as choices in crossing symbols.
Dendograms of treatments, parents, and populations showing the development of genetic material as well as the flow of data. Development of segregating populations from F1 to Fn, and /or clonal stages.
Immediate display and tracking of histories over generations or clonal stages, including past nursery data and data of parents for each population. A “progeny analysis” tool to view the number of descendants from crosses, populations, or parents across generations, as well as their average value and percentage of occurrence for any given trait(s) plus other statistics. Monitor response to selection for, say, days to maturity or stem rust resistance from the F2 to F5 for all or some crosses or parents or specific populations.
Ability to conform naming conventions for populations and even parents to most breeding programs through flexible renaming tools. Tracking of clonal stages each year for each genotype in nurseries or in replicated yield trials.
Nurseries laid out as non-replicated designs with or without checks, or as replicated designs like RCBD or lattices wherein selections may be tracked in replications if desired.
Special ‘Grid’ nursery where repeating check(s) are planted in a grid (columns) down the field, with optional buffers and fillers.
Analysis of data in nurseries for non-replicated or replicated designs, including incomplete block designs.
Relational view of parental descriptor traits for each population as well as with similar traits for all previous generations.
