Courses : Forest Ecology Lecturer :Frischa Adellia Semester : 4thSemester, 2022/2023 Session Selective Breeding Selective breeding is the process of selecting and breeding organisms based on desired traits to be passed on to the next generation. The goal is to increase the presence of certain traits in a population of these organisms. This process has been used widely in agriculture and animal husbandry to produce more productive plant varieties, more resilient livestock, or other types of organisms with desired traits. Selective breeding involves several steps, including: 1. Individual selection: Individuals with desired traits are selected from the existing population. 2. Selective mating: Selected individuals are then selectively mated to combine desired traits. 3. Breeding the next generation: The children resulting from this selective mating are then bred further, by selecting individuals with the desired traits to become the parents of the next generation. 4. Continued evaluation and selection: This process is repeated over and over again, with continuous evaluation of desired traits and selection of appropriate individuals to ensure the desired development is achieved. Selective breeding has become one of the main methods of increasing agricultural yields, increasing the productivity of livestock, and developing other types of organisms with desired traits. Although proven effective, this process requires significant time and effort as well as a deep understanding of the genetics of the organisms involved. The main goal of selective breeding is to increase or maintain desired traits in a population of organisms. Some specific goals include: 1. Increased productivity: Increasing agricultural output or livestock production by producing more productive plant varieties or livestock that are more resilient and produce more yield. 2. Improved quality: Produces organisms of better quality, such as plants with larger fruit, livestock with tastier meat, or flowers with brighter colors. 3. Increased resilience: Developing organisms that are more resistant to disease, pest attacks, or unfavorable environmental conditions, thereby increasing survival and productivity. 4. Adaptation to new environments: Producing varieties of plants or livestock that are better able to survive and adapt to climate changes or other environmental conditions. 5. Increased production efficiency : Creating organisms that require fewer resources for growth and production, thereby reducing costs and increasing sustainability. 6. Development of new traits: Developing organisms with new traits that can provide new economic, environmental, or health benefits. Through selective breeding, breeders can direct the evolution of organisms to achieve various desired goals, which in turn can help increase food production, improve the health of farm animals, and overcome the environmental and climate challenges facing modern agriculture. In conclusion, selective breeding is a process used to improve or maintain desired traits in a population of organisms. The goal is to achieve various goals that include increasing productivity, quality, and resistance of organisms to the environment and disease, as well as adapting to new environmental conditions. Through the process of selecting individuals with desired traits and selective breeding, breeders can create new varieties that are better suited for specific purposes. Selective breeding has become one of the main methods in increasing agricultural yields, livestock production, and the development of other types of organisms. While effective, this process requires time, effort, and a deep understanding of the genetics of the organisms involved. By making judicious use of selective breeding, we can improve agricultural sustainability, increase food availability, and create organisms that are more resilient to the environmental challenges faced in the future.
