Mutation Breeding 

Interest in induced mutation breeding has spiked in China. The technology has been increasingly applied for crop improvement. Research in this field has been a joint effort spanning many sectors, including agriculture, research institutions and universities. More than 40 entities are involved. Cooperation and coordination have yielded remarkable results, placing China at the forefront of research on the application of this technology. As a member of the Steering Committee of the Plant Mutation Breeding Network for Asia and the Pacific, China has long been taking a leading role in implementing cooperative projects under the framework of the Regional Co-operative Agreement for Research, Development and Training Related to Nuclear Science and Technology. 

A total of 1,050 mutant crop varieties have been developed in China by using radiation mutation breeding, accounting for one fourth of all mutants currently listed in the IAEA/FAO's database of mutant varieties produced worldwide. Annually, about 8-10% of the main crop varieties used in agricultural production come from a radiation-induced mutation process. An attempt was made to leverage space technologies in seed breeding, through 17 space trips and the launch on September 9, 2006 of China's seed-breeding satellite, Shijian-8, leading to the development of new types of high-quality germplasm, including dozens of new crop (rice, wheat, tomato, green pepper and sesame) varieties. 

農(nóng)作物誘變育種

中國(guó)農(nóng)作物誘變育種技術(shù)研究發(fā)展迅速，在研究和發(fā)展誘變技術(shù)的同時(shí)，將該技術(shù)與農(nóng)作物改良密切結(jié)合。通過(guò)組織全國(guó)農(nóng)、科、教行業(yè)大聯(lián)合、大協(xié)作，形成了一支包括40多個(gè)單位的國(guó)家核輻射誘變技術(shù)育種研發(fā)隊(duì)伍，促進(jìn)了核輻射誘變技術(shù)育種的持續(xù)發(fā)展，使中國(guó)的核輻射誘變技術(shù)及其育種應(yīng)用研究一直走在世界前列，為國(guó)際原子能機(jī)構(gòu)亞太地區(qū)植物誘變育種項(xiàng)目的牽頭國(guó)、亞太區(qū)域植物突變研究協(xié)作網(wǎng)依托國(guó)。

中國(guó)利用核技術(shù)誘變已育成了1050個(gè)突變品種，占國(guó)際原子能機(jī)構(gòu) /糧農(nóng)組織全球突變品種數(shù)據(jù)庫(kù)所列突變品種的1/4。每年在生產(chǎn)上應(yīng)用的主要農(nóng)作物品種數(shù)量、播種面積里，8%～10%來(lái)自輻射誘變育種。通過(guò)17次太空搭載和2006年9月9日實(shí)踐八號(hào)衛(wèi)星選育出一批優(yōu)異新種質(zhì)、新材料，包括水稻、小麥、番茄、青椒和芝麻等幾十個(gè)農(nóng)作物新品種。
