Abstract
A method is disclosed for forming haploid tomato plants. Plants so formed are normal, flowering plants but are sterile. Methods are taught of doubling the chromosome number of the haploid plants to form fetile, true breeding diploid tomato plants. Such methods are useful in plant breeding programs to produce new assortments of genes in true-breeding lines without the several backcrossing steps otherwise required.
