Abstract
The present invention relates to the field of plant breeding. More specifically, the present invention includes a method of using haploid plants for genetic mapping of traits of interest such as disease resistance. Further, the invention includes a method for breeding corn plants containing quantitative trait loci (QTL) that are associated with resistance to Gray Leaf Spot, a fungal disease associated with Cercospora spp.
Claims16
A method of identifying a corn plant comprising at least one allele associated with Gray Leaf Spot (GLS) resistance allele in a corn plant comprising:
- a) genotyping at least one corn plant with the nucleic acid marker of SEQ ID NO:
- 36, and
- b) selecting at least one corn plant comprising an allele of at least one of said markers associated with Gray Leaf Spot (GLS) resistance.
A method of introgressing a Gray Leaf Spot (GLS) resistance QTL allele into a corn plant comprising:
- a) screening a population with at least one nucleic acid marker to determine if one or more corn plants from the population comprise(s) an allele of said marker associated with a Gray Leaf Spot (GLS) resistance QTL associated with marker NC0052741 on chromosome 1;
- and
- b) selecting from said population at least one corn plant comprising an allele of said marker associated with a Gray Leaf Spot (GLS) resistance.
