However, the current plant breeding methods are entirely based on scientific principles of plant sciences. Pedigree breeding is a method of genetic improvement of self-pollinated species […] Plant breeding can be broadly defined as alterations caused in plants as a result of their use by humans, ranging from unintentional changes resulting from the advent of agriculture to the application of molecular tools for precision breeding. Conventional plant breeding has been going on for hundreds of years, and is still commonly used today. Traditional improvement methods are time-consuming and troublesome due to the time of breeding, and there is a problem with the choice of criteria appropriate for breeding purposes. Plant breeders now use molecular and genetic techniques to selectively identify phenotypes and genotypes that are associated with traits of interest. New plant breeding techniques and the dignity of living beings When methods in genetic engineering started to be used in breeding tech-niques, there was considerable con-troversy over whether the genome of animals, plants and other living beings could be interfered with and modified in such a way as had not previously been possible. principles of plant breeding icar ecourse pdf book. Additional improvements in the traditional techniques may be expected to facilitate the breeding process but, it is safe to say that the limits of conventional breeding methods have .

It is a purposeful manipulation of plants to create desired plant types that are better suited for cultivation, give better yield and are disease resistant. Whereas biosafety issues of the application of GM crops were actively and con-troversially discussed in the last decades, the application of other biotechno- plant breeding techniques“ (NPBT), are different to both conventional breeding approaches as well as standard GM developments (LUSSER et al.
