Using mutation breeding to improve plant genetic characteristics
Known as mutation breeding, plant breeders induce inheritable changes in the genetic background of a plant by using irradiation and chemicals, and then select offspring with the characteristics they are looking for.
UN Food and Agriculture Organization (FAO) and International Agricultural Exchange Association (IAEA) scientists have used mutation breeding to improve oil quality by inducing changes in the plant's fatty acid composition, and to raise the yields of important oilseed crops. With sesame, the researchers increased the length of the fruiting zone on the stem, the number of capsules or fruits, the uniformity of ripening and the plant's tolerance to important diseases.
1. The value of plant genetic resources for food and agriculture ultimately lies in their utilization. Promoting plant breeding and improvement is one way of sharing the benefits of these resources.
The Encyclopedia of World Problems and Human Potential is a unique, experimental research work of the Union of International Associations. It is currently published as a searchable online platform with profiles of world problems, action strategies, and human values that are interlinked in novel and innovative ways. These connections are based on a range of relationships such as broader and narrower scope, aggravation, relatedness and more. By concentrating on these links and relationships, the Encyclopedia is uniquely positioned to bring focus to the complex and expansive sphere of global issues and their interconnected nature.
The initial content for the Encyclopedia was seeded from UIA’s Yearbook of International Organizations. UIA’s decades of collected data on the enormous variety of association life provided a broad initial perspective on the myriad problems of humanity. Recognizing that international associations are generally confronting world problems and developing action strategies based on particular values, the initial content was based on the descriptions, aims, titles and profiles of international associations.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
