Claims
- 1. A method for identifying alleles associated with agronomic fitness of soybean comprising:
- a) selecting a sample of current-day elite lines of soybean to form an elite population;
- b) selecting the predominant and earliest known ancestral lines of said elite lines by considering the pedigrees of said elite lines;
- c) conducting a genetic marker survey to determine the genotype of said elite lines and said ancestral lines;
- d) using the pedigrees of said elite lines and genotypes of said ancestral lines to calculate the probability of each elite line inheriting each allele from said ancestral lines;
- e) calculating the expected allele frequency of each allele within said elite population by averaging the probabilities calculated in step d) for each elite line;
- f) calculating the observed allele frequency within said elite population;
- g) comparing said observed allele frequency with said expected allele frequency for each said allele in said elite population to identify alleles at each locus that have been inherited more frequently than expected; and
- h) producing soybean plants with superior agronomic fitness;
- such that said soybean plants with superior agronomic fitness can be efficiently identified with said genetic markers that are diagnostic of said alleles that have been inherited more frequently than expected.
- 2. A method of claim 1, wherein in step c) the genetic marker is selected from the group consisting of 1202, 1443, 1522, 1525, 1596, 1203, 1329, 1529, 1593, 1587, AP5C, AP5G, AP8H, AP6, AP8F, AP4C, and AP5B is used to conduct said genetic marker survey.
- 3. A method for breeding agronomically superior soybean plants, comprising:
- a) identifying the genotype of a number of soybean lines by conducting a genetic marker survey using a genetic marker selected from the group consisting of 1202, 1443, 1522, 1525, 1596, 1203, 1329, 1529, 1593, 1587, AP5C, AP5G, AP8H, AP6, AP8F, AP4C, and AP5B; and
- b) selecting parent soybean lines identified in step a) that, when crossed, produce an ideal segregant containing more favorable alleles than either parent.
- 4. A method of claim 1 wherein step g) is performed using a chi-squared test for the statistical significance of the deviation of observed allele frequency from expected allele frequency.
- 5. A method of claim 1 wherein step g) is performed by computing the distribution of possible allele counts by the generalized binomial distribution, and using said binomial distribution to compute a cumulative probability that provides a statistical measure of the significance of the deviation of observed allele frequency from expected allele frequency.
