HAL1 gene from yeast was transformed into main cultivars ‘Jijing 88’and ‘Jijing 83’of Jilin provincemediated by Agrobacterium tumefaciens. Total 246 transgenic plants were validated by PCR and southern blot. In al-kali tolerance experiments with pH 11, Na OH and Na₂CO₃, 7 transgenic plants of ‘Jijing 83’falling in class 1 for al-kali tolerance and 29 transgenic plants of ‘Jijing 83’falling in class 3 were obtained. Three transgenic plants of ‘Jijing88’falling in class 1 for alkali tolerance and 8 transgenic plants of ‘Jijing 88’falling in class 3 were obtained.
