摘要： 盐害是制约小麦生产的主要因素，为研究小麦重组自交系后代在田间盐环境的耐盐性。本研究以2个小麦品种‘宁春27号’、‘宁春4号’以及2个亲本杂交后代中8个小麦品系‘R9’、‘R32’、‘R39’、‘R75’、‘R88’、‘R89’、‘R103’、‘R108’、‘R117’、‘R129’、‘R130’为研究对象，在田间盐环境下通过对全生育期的农艺性状进行调查分析对其耐盐性进行评价。试验结果表明：在全盐含量为0.35%的田间盐环境下，通过对试验材料进行株高、穗长、穗重、穗粒数、小区产量进行调查分析，‘R32’株高最高，明显高于亲本，‘R75’的穗长、穗重、穗粒数都明显高于其亲本，‘R88’、‘R108’的小区产量最高，明显高于其亲本。因此，通过田间表现及农艺性状比较，‘R75’、‘R88’、‘R108’田间耐盐性较强。

Abstract: Salt stress is one of the main factors that restrict wheat yield. In order to study the salt tolerance of wheat recombinant inbred lines in filed salt environment, the authors used two wheat varieties ‘Ningchun No.27’, ‘Ningchun 4’ and eight wheat lines ‘R9’, ‘R32’, ‘R39’, ‘R75’, ‘R88’, ‘R89’, ‘R103’, ‘R108’, ‘R117’, ‘R129’, ‘R130’ as the objects, to evaluate salt tolerance through investigation and analysis of agronomic characters during the whole growth period. The experiment results showed that in field salt environment with 0.35% total salt content, the analysis of plant height, ear length, ear weight, grain number per spike and yield per plot indicated that ‘R32’ strain had the highest plant height, significantly higher than that of the parents, ear length, ear weight and grain number per panicle of‘R75’ were significantly higher than those of the parents, and ‘R88’, ‘R108’ had obviously higher plot yield than that of their parents. Therefore, by comparing the field performance and agronomic characters, ‘R75’, ‘R88’ and ‘R108’ had relatively strong field salt tolerance.
