An international team of scientists has created the first haplotype map of wheat that gives a detailed description of genetic differences among 62 wheat lines from around the world, says Sci-News.com. Haplotypes are groups of genes that usually are inherited together. Plant breeders often look at the genetic makeup of plants for desirable traits, such as disease or drought resistance, for new varieties of the organism. “The haplotype map gives them quick access to rich, genetic variation data that increases the precision of mapping genes in a plant genome, and improves scientists’ ability to select the best lines in breeding trials,” says Sci-News.com.
