METHODS FOR IDENTIFYING PECAN TREE CULTIVARS

1 . A method of identifying a cultivar of a pecan tree, comprising detecting a polymorphism listed in Table 3 from a sample of nucleic acids from said pecan tree, wherein the presence of said polymorphism identifies said cultivar of said pecan tree.

2 . The method of claim 1 , wherein said cultivar is Alley, Amling, Apache, Barton, Brooks, Burkett, Byrd, Caddo, Candy, Cape Fear, Carmichael, Carter, Cheyenne, Choctaw, Clark, Creek, Curtis, Dependable 6-2, Dependable 8-3, Desirable 5-2, Eclipse, Elliott, Evers, Excel, Forkert, Gafford, Giles, Halbert, Humble, Jackson BW, Jackson LA, Jenkins, Kanza, Kiowa, Lakota, Mahan, Major, Mohawk, Moreland, Nacono, Oconee, Odom, Pawnee, Podsednik, Riverside, Russell, Schley, Shawnee, Starking Hardy Giant (SHG), Shoshoni, Sioux, Stuart, Success, Summer, Syrup Mill, VC168, W. Schley, Wichita, Witte, or Zinner.

3 . The method of claim 1 , wherein said polymorphism comprises an insertion/deletion or single nucleotide polymorphism detected by amplification of a first nucleic acid segment comprising said first insertion/deletion or single nucleotide polymorphism from said sample of nucleic acids, and analysis of said first nucleic acid segment by high-resolution melting or sequencing to detect said first insertion/deletion or single nucleotide polymorphism.

4 . The method of claim 1 , wherein said polymorphism is within a locus in the genome of said pecan tree having a nucleotide sequence of any one of SEQ ID NOs:33-49.

5 . The method of claim 4 , wherein said polymorphism is flanked by a pair of oligonucleotide primers of sufficient length to hybridize specifically to any one of SEQ ID NOs:33-49.

6 . The method of claim 5 , wherein said pair of oligonucleotide primers is selected from the group consisting of SEQ ID NO:1 and SEQ ID NO:2, SEQ ID NO:3 and SEQ ID NO:4, SEQ ID NO:5 and SEQ ID NO:6, SEQ ID NO:7 and SEQ ID NO:8, SEQ ID NO:9 and SEQ ID NO:10, SEQ ID NO:11 and SEQ ID NO:12, SEQ ID NO:13 and SEQ ID NO:14, SEQ ID NO:15 and SEQ ID NO:16, SEQ ID NO:17 and SEQ ID NO:18, SEQ ID NO:19 and SEQ ID NO:20, SEQ ID NO:21 and SEQ ID NO:22, SEQ ID NO:23 and SEQ ID NO:24, SEQ ID NO:25 and SEQ ID NO:26, SEQ ID NO:27 and SEQ ID NO:28, SEQ ID NO:29 and SEQ ID NO:30, and SEQ ID NO:31 and SEQ ID NO:32.

7 . The method of claim 3 , further comprising detection of a second polymorphism by amplification of a second nucleic acid segment comprising said second single nucleotide polymorphism from said sample of nucleic acids, and analysis of said second nucleic acid segment by high-resolution melting or sequencing to detect said second single nucleotide polymorphism.

8 . The method of claim 7 , further comprising detection of a third single nucleotide polymorphism by amplification of a third nucleic acid segment comprising said third single nucleotide polymorphism from said sample of nucleic acids, and analysis of said third nucleic acid segment by high-resolution melting or sequencing to detect said third single nucleotide polymorphism.

9 . A kit for determining a cultivar of a pecan tree, said kit comprising a pair of oligonucleotide primers of sufficient length to hybridize specifically to any one of SEQ ID NOs:33-49, wherein said cultivar is Alley, Amling, Apache, Barton, Brooks, Burkett, Byrd, Caddo, Candy, Cape Fear, Carmichael, Carter, Cheyenne, Choctaw, Clark, Creek, Curtis, Dependable 6-2, Dependable 8-3, Desirable 5-2, Eclipse, Elliott, Evers, Excel, Forkert, Gafford, Giles, Halbert, Humble, Jackson BW, Jackson LA, Jenkins, Kanza, Kiowa, Lakota, Mahan, Major, Mohawk, Moreland, Nacono, Oconee, Odom, Pawnee, Podsednik, Riverside, Russell, Schley, Shawnee, Starking Hardy Giant (SHG), Shoshoni, Sioux, Stuart, Success, Summer, Syrup Mill, VC168, W. Schley, Wichita, Witte, or Zinner.

10 . The kit of claim 9 , wherein said kit comprising the following oligonucleotide primer sets: SEQ ID NO:1 and SEQ ID NO:2; SEQ ID NO:3 and SEQ ID NO:4; SEQ ID NO:5 and SEQ ID NO:6; SEQ ID NO:7 and SEQ ID NO:8; SEQ ID NO:9 and SEQ ID NO:10; SEQ ID NO:11 and SEQ ID NO:12; SEQ ID NO:13 and SEQ ID NO:14; SEQ ID NO:15 and SEQ ID NO:16; SEQ ID NO:17 and SEQ ID NO:18; SEQ ID NO:19 and SEQ ID NO:20; SEQ ID NO:21 and SEQ ID NO:22; SEQ ID NO:23 and SEQ ID NO:24; SEQ ID NO:25 and SEQ ID NO:26; SEQ ID NO:27 and SEQ ID NO:28; SEQ ID NO:29 and SEQ ID NO:30; and SEQ ID NO:31 and SEQ ID NO:32.

11 . The kit of claim 11 , further comprising instructions for determining said cultivar of said pecan tree.
