Characterization of Plant Genotypes Using a Rapid Tissue Hybridization Method. Plant tissue culture was a new addition to the methods of plant breeding that developed around the 1950s. Plant breeding can enhance existing crops or help evolve new species for our food supply. Biology Article. Feel free to contact the Admin if you have any doubts or quires. This manipulation involves either controlled pollination, genetic engineering, or both. Applications of Molecular Biology in Plant Breeding: The Detection of Genetic Variation and Viral Pathogens. 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. 2 Methods of Plant Breeding 2.1 Conventional Methods. In this four lecture series, we'll first learn about the structure-function of plants and of plant cells. Since the conventional breeding techniques could not fulfil the required demand of crops, tissue culture came around as a grand leap in breeding … PLANT BREEDING & HORTICULTURE. Thus plant breeding toda y is largely a science with litt le involvement of art. Plant breeding is a critical tool in the fight for food security and responsible environmental stewardship in the 21st century. ... Plant Breeding Institute, Trurnpington, Cambridge CB2 2LQ, UK. For the easy navigation, the topics were categorized into modules. Plant breeding is the purposeful manipulation of plant species in order to create desired genotypes and phenotypes for specific purposes. Plant breeding is a discipline of applied plant science that deals with the improvement of crop plants through the production of hybrid crop plants, which are superior to the original plant varieties. Plant Tissue Culture. The Detection of Viral Pathogens By a Molecular Hybridization Assay. i) It produces more productive crop plants and there by improves food production.
