Abstract

With the rediscovery of Mendel’s laws in 1900, radical changes took place in plant breeding methods. The new science of genetics contributed new concepts: the gene, the role of chromosomes as gene carriers, gene linkage, the Mendelian basis of continuous variation, heterosis, maternal inheritance, experimental mutagenesis, polyploidy and gene-enzyme relationships. These scientific discoveries rapidly permeated breeding theory, to the point that plant breeding became synonymous with applied genetics. It should, nevertheless, be emphasized that the science of plant breeding has received and continues to assimilate relevant contributions from cytology, systematics, physiology, pathology, entomology, chemistry, statistics, and, more recently, from molecular biology.KeywordsTransgenic PlantPhytic AcidCucumber Mosaic VirusCoffee BerryTransgenic TomatoThese keywords were added by machine and not by the authors.
