Review Study on the Maintenance of Improved Crop Varieties for Protecting Their Popularity in Seed Multiplication Systems

Improved crop varieties are the result of important plant breeding techniques, have several benefits, such as higher yields, resistance to pests and diseases, and endurance under adverse conditions like salinity and drought. These varieties are losing their uniqueness and health if they are not properly maintained. This is mostly caused by contaminating and degrading factors, such as genetic drift, outcrossing, volunteer plants, mutation, environmental stressors, and diseases spread by seeds. Proper seed management during seed multiplication can prevent this degeneration. This review study aimed to keep better varieties in seed multiplication systems. It looks at the significance of genetic purity and the variables that influence it. A thorough discussion of the techniques for preserving genetic integrity, including roguing, isolation, and seed certification. It is also stressed that policy support is needed for farmer education, seed certification, and research to preserve the benefits of these varieties. This evaluation offers valuable insights into the optimal management procedures during seed multiplication to guarantee that enhanced crop varieties continue to be useful instruments for boosting agricultural productivity and food security. It accomplishes this by undertaking a detailed examination of current practices and advances.
