PGR, or Plant Genetic Resources, is a field of research that focuses on the conservation, characterization, and utilization of genetic diversity in plants. This includes collecting and storing seeds, tissues, and other plant materials from a wide variety of species in order to preserve their genetic information for future use. PGR research also involves studying the traits and genetic characteristics of different plant varieties to identify potential sources of valuable traits for breeding purposes. By studying and preserving plant genetic resources, researchers aim to improve crop resilience, productivity, and sustainability in agriculture.
