Abstract
Improved molecular breeding methods include a method in which an association data set is developed by associating the phenotypes of a broad population of individuals with the individual genotypes. The association data set is used in conjunction with a growth model in order to select breeding pairs likely to generate offspring with one or more desirable traits.
Claims28
A method for selecting individuals in a breeding program, said method comprising:
- a. growing a genetically diverse population of training individuals;
- b. phenotyping the genetically diverse population of training individuals to generate a phenotype training data set;
- c. associating the phenotype training data set with a genotype training data set comprising genetic information across the genome of each training individual, using a biological model, estimating effects of genotypic markers and linking the estimation of effects of genotypic markers with the biological model to generate an association training data set;
- d. genotyping a genetically diverse population of breeding individuals;
- e. selecting breeding pairs from the genetically diverse population of breeding individuals based plant genotypes using the association training data set and a biological model, estimating effects of genotypic markers and linking the estimation of effects of genotypic markers with the biological model to select breeding pairs likely to generate offspring with one or more desired traits;
- f. crossing the breeding pairs to generate offspring;
- and
- g. growing the offspring with the one or more desired traits.

A method for selecting individuals in a breeding program, said method comprising:
- a. growing a genetically narrow population of training individuals;
- b. phenotyping the genetically narrow population of training individuals to generate a phenotype training data set;

- d. genotyping a genetically narrow population of breeding individuals;
- e. selecting breeding pairs from the genetically narrow population of breeding individuals based plant genotypes using the association training data set and a biological model, estimating effects of genotypic markers and linking the estimation of effects of genotypic markers with the biological model to select breeding pairs likely to generate offspring with one or more desired traits;
- f. crossing the breeding pairs to generate offspring;
- and
- g. growing the offspring with the one or more desired traits.

A method for predicting genetically based disease risk for individuals in a personalized medicine program comprising:
- a. identifying a first set of genetically diverse populations of humans as training individuals;
- b. phenotyping the training individuals for disease status to generate a phenotype training data set;
- c. genotyping the training individuals using a set of genome wide genetic markers to generate a genotype training data set;
- d. associating the phenotype training data set with the genotype training data set;
- e. estimating effects of the genome wide genetic markers from the genotype training data set and linking the estimation of the effects of the genome wide genetic markers with a biological disease model to generate an association training data set;
- f. genotyping a patient using the set of genome wide genetic markers to generate a patient genomic data set;
- and
- g. estimating effects of the genome wide genetic markers from the patient genomic data set and linking the estimation of the effects of the genome wide genetic markers with the biological disease model to predict the patient's disease risk.
