| 中文摘要: |
| 陇春22号是从墨西哥国际玉米小麦改良中心引进,历经10年,进一步筛选的优质抗锈春小麦新品种,多年田间鉴定表现抗旱性强,品质优良。为了进一步确定其抗旱性和品质特性,对该品种在干旱条件下的形态特征、生理生化指标、田间产量指标、优质亚基进行了初步的鉴定评价。结果表明:陇春22号萌芽期、幼苗期以及成熟期抗旱性强,含有17+18、5+10优质亚基,适合在甘肃及宁夏等地的干旱半干旱地区大面积推广种植。 |
| 英文摘要: |
| 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. |
