Individual hybrid plants can be produced easily and inexpensively, but what about thousands or millions of them? Varietal purity of the seed is clearly identified from its breeder seed and is genetically pure. Hybrid cultivars: disadvantages. * Hybridization can bring genetic defects in hybrid plants such as the repression of flowering (never bloom), premature death, sterility (the hybrid will produce sterile flowers unable to form viable seeds), hybrid breakage (the hybrid plant is fertile but when leaves offspring, the new characteristics obtained are not transmitted, that is, the .
