山东农业大学利用生物技术与常规育种相结合的方法,在国内外首次成功地将小牛胸腺DNA导入普通小麦,育成小麦新品系——D041。1993年在山东省种植2万亩,最高亩产可达1080公斤,比目前推广的小麦品种增产10-15%。蛋白质含量15%以上,赖氨酸含量0.39%以上,蛋氨酸含量0.52%。并具有高抗条锈病、白粉病和干热风,后期绿叶功能时间长、中熟偏早、灌浆速度快等特点,千粒重稳定在50克左右,特别适宜晚播。外源DNA导入技术是一条高效育种的途径,可

Shandong Agricultural University, using a combination of biotechnology and conventional breeding methods, the first successful introduction of calf thymus DNA into common wheat at home and abroad to cultivate 20,000 acres of new wheat lines, the highest mu yield Up to 1080 kg, 10-15% more than the current promotion of wheat varieties. Protein content of more than 15%, lysine content of 0.39%, methionine content of 0.52%. And with high resistance to stripe rust, powdery mildew and dry hot wind, late green leaf function for a long time, too late in the mature, fast filling and other characteristics, 1000 grain weight stable at about 50 grams, especially suitable for late sowing. Foreign DNA introduction is an efficient breeding method
