A true-breeding plant is one that, when self-fertilized, only produces offspring with the same traits. True-breeding organisms are genetically identical and have identical alleles for specified traits. It is a kind of breeding wherein the parents would produce offspring that would carry the same phenotype. Basically true means identical or same. Hope this somewhat helped :)
