Abstract: The present invention provides an inbred corn line designated JH6530, methods for producing a corn plant by crossing plants of the inbred line JH6530 with plants of another corn plant. The invention further encompasses all parts of inbred corn line JH6530, including culturable cells. Additionally provided herein are methods for introducing transgenes into inbred corn line JH6530, and plants produced according to these methods.

Abstract: Provided herein are methods for mapping quantitative trait loci in a connected population of organisms. The invention includes evaluating associations between markers and a trait of interest using network population mapping (NPM). The methods include assembling a network of individual members for association mapping, wherein the members are connected at the allelic level. Members of the network are grouped according to a shared haplotype at one or more marker loci, and the network can be used to identify or validate QTL within the chromosomal region surrounding or flanked by the marker loci. The methods further include a means for estimating and ranking the effects of multiple alleles across the mapping population. Further provided is a novel simple interval mapping model as well as a novel composite interval mapping model for evaluating allele-specific associations across a connected mapping population.
