[Method] Ripe pollen grains of upland cotton were irradiated by 60Co-γ Ray with doses of 5, 10, 15, and 20 Gy, respectively, to learn radiation effect and select appropriate dose. [Result] Most properties of M1 obviously showed variation when dose was over 10 Gy; vitality, growth, and fertility were greatly inhibited when dose was 15 Gy which was almost semi-lethal concentration, and variation species were richest at the same time, which provided materi- als for practical breeding. [Conclusion] 60Co-γ Ray of 15 Gy is more suitable for mutagenesis research on ripe pollen grains of upland cotton.展开更多

Application of nuclear technique in agriculture (Nuclear Agricultural Sci-ences) based on the development of related sci-ence and technology is a high-tech area, and also a significant aspect of non-electrical power appli-cation of nuclear technique. As an important com-ponent of agricultural science and technology, Nu-clear technique application in agricultural field has achieved a lot and made remarkable contributions to the economic, social and ecological develop-ment of China. The current paper reviews the achievements, and presents the situation of the application of nuclear technique in the Chinese a-griculture briefly. The author strongly suggests that Chinese government should pay more attention to the study on the application of nuclear technique in agriculture, in order to promote its development and contribute more to the Chinese society and a-griculture.展开更多
