Abstract:
The present disclosure is in the field of plant breeding. The disclosure provides methods for breeding cotton plants having a staygreen trait using marker-assisted selection. The disclosure further provides germplasm that stays green under high drought stress and provide yield advantage over non-staygreen germplasm. The disclosure also provides genetic markers associated with staygreen QTLs for introgressing these QTLs into elite germplasm in a breeding program and producing novel cotton germplasm that performs better under water-limited conditions.
Abstract:
The present disclosure is in the field of plant breeding and disease resistance. The disclosure provides methods for breeding canola plants having clubroot resistance using marker-assisted selection. The disclosure further provides germplasm resistant to various Plasmodiophora brassicae pathotypes including pathogtype 5x. The disclosure also provides markers associated with clubroot resistance loci for introgressing these loci into elite germplasm in a breeding program, thus producing novel clubroot resistant germplasm, e.g., spring canola varieties resistant to pathogtype 5x.
Abstract:
The present invention relates to methods for breeding cotton plants containing a recombination event such that quantitative trait loci (“QTL”) on chromosome 11 are present, associated with resistance to both root-knot nematode (“RKN”) and reniform nematode (“REN”) infection (“stacked nematode resistance”). The invention further provides germplasm and the use of germplasm containing such stacked nematode resistance as a source of nematode resistance alleles for introgression into elite germplasm in a breeding program, thus producing novel elite germplasm comprising the stacked nematode resistance trait.
