| Abstract: |
| Longchun 22 was introduced from CIMMYT by further filtrating for a period of ten years.It displays strong drought-resistance and good-quality by field identity for many years.To confirm further and give prominence to its drought-resistance and good-quality character,Longchun 22 is identified and evaluated elementarily from the character of form,physiological and biochemical indexes,field yield indexes and good-quality subunits in drought.Its will offer reliable academic basis on theory to further generalization of Longchun No.22.The result of study indicates that the drought-resistance of Longchun No.22 is obvious in the stages of germination,young seedling and mature.It contains HMW glutenin subunits 17+18 and 5+10.And it adapts to planted and generalized widely in arid and semiarid regions of Gansu and Ningxia,et al. |
