Abstract
The present invention relates to methods and compositions for identifying, selecting and/or producing a Disease resistant soybean plant or germplasm using markers, genes and chromosomal intervals derived from Glycine tomentella PI441001, PI441008, PI446958, PI509501, PI583970, or PI483224. A soybean plant or germplasm that has been identified, selected and/or produced by any of the methods of the present invention is also provided. Disease resistant soybean seeds, plants and germplasms are also provided.
Claims10
An elite Glycine max plant having in its genome a chromosomal interval from a wild glycine plant, wherein said chromosomal interval confers increased Asian soy rust (ASR) resistance as compared to a control plant not comprising said chromosomal interval, wherein the chromosomal interval comprises SEQ ID NOs:
- 1, 2, 3, 4, 5, or a portion of any thereof.
The plant of claim 3, wherein the chromosomal interval is derived from Glycine tomentella chromosome 5 at an approximate mapping interval of 0.02-1.19 Mb.
A method of producing a Glycine max plant having increased resistance to Asian soybean rust (ASR), the method comprising the steps of:
- a. providing a first Glycine max plant comprising in its genome a chromosomal interval corresponding to any one of SEQ ID NOs:
- 1-5, or a portion thereof, wherein said first Glycine max plant has increased resistance to ASR;
- b. crossing the Glycine max plant of a) with a second Glycine max plant not comprising said chromosomal interval;
- c. selecting a progeny plant from the cross of b) by isolating a nucleic acid from said progeny plant and detecting within said nucleic acid an allele that associates with increased ASR resistance and further wherein said allele is closely linked with or located within the chromosome intervals corresponding to any one of SEQ ID NOs:
- 1-5 or a portion thereof, thereby producing a Glycine max plant having increased resistance to ASR.
A plant produced by the method of claim 10.
A primer diagnostic for ASR resistance, wherein said primer can be used in a PCR reaction to indicate the presence of an allele associated with ASR resistance, wherein said allele is any favorable allele as described in Tables 1-5.
