东北师范大学生物系在国内首次建立两套小冰麦异附加系,对发展我国小麦染色体工程育种新途径和利用天兰冰草的有用基因改良小麦,培养有抗病性和抗逆性的小麦品种具有重要意义。用异源基因改良小麦是小麦育种的重要途径。天兰冰草含有许多对改良小麦非常重要的基因。通过染色体工程的途径把这些基因转移 Department of Biology, Northeast Normal University, the first time in the country to establish two sets of small wheat alien addition lines, the development of China’s new way of chromosome breeding of wheat and the use of Tianrencao useful genetically modified wheat, cultivate disease resistance and stress resistance of wheat Variety is of great significance. Improving Wheat with Heterologous Genes Is an Important Way of Wheat Breeding. Celastrus contains many genes that are important for improved wheat. These genes are transferred by chromosomal engineering
