Plant breeding method
First Claim
1. A method of predicting a value of a phenotypic trait in a target plant population, the method comprising:
- (a) providing an association between at least one genetic marker and the phenotypic trait;
wherein the association is evaluated in a first plant population, the first plant population being an established breeding population or a portion thereof;
wherein the association is evaluated in the first plant population according to a statistical model that incorporates a genotype of the first plant population for a set of genetic markers and a value of the phenotypic trait in the first plant population; and
, (b) providing the value of the phenotypic trait in at least one member of the target plant population, wherein the providing comprises predicting the value from the association of (a) and from a genotype of the at least one member for the at least one genetic marker associated with the phenotypic trait.

Abstract
Methods for using genetic marker genotype (e.g., gene sequence diversity information) to improve the process of developing plant varieties (e.g., single cross hybrids) with improved phenotypic performance are provided. Methods for predicting the value of a phenotypic trait in a plant are provided. The methods use genotypic, phenotypic, and optionally family relationship information for a first plant population to identify an association between at least one genetic marker and the phenotypic trait, and then use the association to predict the value of the phenotypic trait in one or more members of a second, target population of known marker genotype. Methods for identifying new allelic variants affecting the trait are also provided. Plants selected, provided, or produced by any of the methods herein, transgenic plants created by any of the methods herein, and digital systems for performing the methods herein are also provided.

52. A method of selecting a plant, the method comprising:
-
(a) providing an association between at least one genetic marker and the phenotypic trait;
wherein the association is evaluated in a first plant population, the first plant population being an established breeding population or a portion thereof;
wherein the association is evaluated in the first plant population according to a statistical model that incorporates a genotype of the first plant population for a set of genetic markers and a value of the phenotypic trait in the first plant population; and
,(b) providing one or more plants from one or more non-adapted lines, wherein the providing comprises selecting one or more plants for a selected genotype comprising the at least one genetic marker associated with the phenotypic trait. - View Dependent Claims (53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87)
