Abstract
This invention relates to methods for identifying wheat plants that having increased fructan/arabinoxylan. The methods use molecular markers to identify and to select plants with increased fructan/arabinoxylan or to identify and deselect plants with decreased fructan/arabinoxylan. Wheat plants generated by the methods of the invention are also a feature of the invention.
Claims18
A method of identifying a wheat plant that comprising at least one allele of a marker locus wherein the method comprises:
- a. obtaining a wheat plant sample;
- and
- b. detecting an increased fructan/arabinoxylan allele of a marker locus located within a chromosomal interval comprising and flanked by a left and right interval marker for QTL 1A, QTL 1B, QTL 2B-1, QTL 2B-2, QTL 2D, QTL 6B, QTL 7A-1, QTL 7A-2, or QTL 7B.
A method of marker assisted selection comprising:
- a. obtaining a first wheat plant having at least one allele of a marker locus for increased fructan/arabinoxylan, wherein the marker locus is located is located within a chromosomal interval comprising and flanked by a left and right interval marker for QTL 1A, QTL 1B, QTL 2B-1, QTL 2B-2, QTL 2D, QTL 6B, QTL 7A-1, QTL 7A-2, or QTL 7B;
- b. crossing the first wheat plant to a second wheat plant;
- c. evaluating the progeny for the at least one allele;
- and
- d. selecting progeny plants that possess the at least one allele.
A wheat crop comprising wheat plants having one or more alleles of marker loci for increased fructan/arabinoxylan flanked by a left and right interval marker for QTL 1A, QTL 1B, QTL 2B-1, QTL 2B-2, QTL 2D, QTL 6B, QTL 7A-1, QTL 7A-2, or QTL 7B.
A method of planting and harvesting a crop of wheat, the method comprising
- a. planting a field with wheat seed, wherein at least 80% of the seed planted in the field comprises one or more alleles of a marker locus for increased fructan/arabinoxylan, wherein each of the one or more marker loci is located is located within a chromosomal interval comprising and flanked by a left and right interval marker for QTL 1A, QTL 1B, QTL 2B-1, QTL 2B-2, QTL 2D, QTL 6B, QTL 7A-1, QTL 7A-2, or QTL 7B;
- b. growing wheat plants from the planted wheat seed;
- and
- c. harvesting the wheat plants from the field and thereby generating a wheat crop.
