Doubled Haploids in Plant Breeding What is a doubled haploid plant? Cells are the building blocks of plants. A doubled haploid plant has cells containing 2 gene sets which are exactly identical. Each cell contains 2 sets of genetic information which are almost (but not exactly) identical. For example, one gene set may carry a gene for disease resistance when Ho
