Utility of SNP markers associated with major soybean plant maturity and growth habit genomic regions

摘要

The invention includes methods and compositions of genomic regions for screening and selecting plants and seeds from the genus Glycine associated with soybean plant maturity and growth habit. The invention also includes methods and compositions for screening plants and seeds from the genus Glycine with markers associated with genomic regions that are related to the plant maturity and plant growth habit of Glycine plants.

1. A method of establishing where a soybean plant or soybean seed should be grown by determining an allelic combination of a soybean plant or soybean seed, comprising:
a. obtaining DNA from said soybean plant or soybean seed; b. determining the genotype of said soybean plant or soybean seed by
i. determining if alleles at a locus within maturity genomic region 1 are homozygous or heterozygous by detecting via an assay a first maturity marker genetically linked to said maturity genomic region 1, and said first maturity marker is located within 20 centiMorgans (cM) of SEQ ID NO: 149;ii. determining if alleles at a locus within maturity genomic region 2 are homozygous or heterozygous by detecting via an assay a second maturity marker genetically linked to said maturity genomic region 2, and said second maturity marker is located within 20 cM of SEQ ID NO: 158;iii. determining if alleles at a locus within maturity genomic region 3 are homozygous or heterozygous by detecting via an assay a third maturity marker genetically linked to said maturity genomic region 3, and said third maturity marker is located within 20 cM of SEQ ID NO: 169; c. determining said allelic combination of said alleles within maturity genomic regions 1, 2, and 3; and d. assigning a maturity group value to said soybean plant or soybean seed based on said allelic combination.
