对8个耐盐小麦品种的重要农艺性状进行了研究,结果表明:盐胁迫下小麦产量构成因素中,单位面积穗数起着决定性的作用,其次是穗粒数,千粒重对产量的影响最小。盐胁迫下小麦能够顺利通过苗期,是小麦最基本的耐盐表现;个体分蘖力强,是提高耐盐小麦产量的基础。选育苗期耐盐力好、分蘖力强、成穗率高的多穗品种,同时兼顾大穗、多粒,可做为小麦耐盐育种的方向。
The important agronomic traits of eight salt-tolerant wheat cultivars were studied. The results showed that panicle number per unit area was the decisive factor in the yield components of wheat under salt stress, followed by the number of grains per spike and the effect of 1000-grain weight on yield. Under salt stress, wheat can successfully pass the seedling stage and is the most basic salt tolerant of wheat. Individual tillering ability is the basis of improving the yield of salt-tolerant wheat. Breeding seedling salt tolerance, strong tillering ability, a high percentage of ear spike varieties, taking into account the big spike, multi-grain, can be used as salt-resistant wheat breeding direction.
