对耐湿性强弱不等的１０个小麦品种，按Ｇｒｉｆｉｎｇ方法４配制成４５个双列杂交组合。在小麦对湿害最敏感的孕穗期进行连续２５天的水渍处理，以主茎绿色叶片数为指标，对亲本及Ｆ１进行耐湿性鉴定分析。结果表明，小麦亲本间对水渍的敏感性存在显著差异，亲本间耐湿性的一般配合力及组合间特殊配合力的差异也达显著水平。参试亲本中，Ｃｏｍｐｔｏｎ不仅本身耐湿性强，而且耐湿性的一般配合力效应值大，特殊配合力方差大，具有较大的利用潜力；水里占、西风和农林４６次之；宁麦３号的耐湿性差，一般配合力低，特殊配合力方差小，在耐湿性育种中不宜利用。在耐湿性变异中，遗传变异占７１．５％，加性变异占５７．３％，显性度为０．５。因此，通过合理选配亲本和后代早期选择，从遗传上改良小麦的耐湿性是可能的
For 10 wheat cultivars with different moisture resistance, 45 pairs of crosses were made according to Grifing method 4. Waterlogging treatment was carried out for 25 consecutive days at the booting stage which is most sensitive to the damage of wheat, and the moisture resistance of the parents and F1 was analyzed by taking the number of main stem green leaves as an index. The results showed that the sensitivity of wheat parents to waterlogging was significantly different, and the differences of the general combining ability and the special combining ability among the parents were also significant. Among the parents tested, Compton not only possesses high moisture resistance, but also has the general effect of combining ability of moisture resistance with large variance of special combining ability and great potential for utilization. The ratio of water to westerly and agriculture 46 times; Number of poor moisture resistance, the general with low, with a small variance of combining ability, should not be used in moisture-resistant breeding. In the variation of moisture tolerance, genetic variation accounted for 71.5%, additive variation accounted for 57.3%, the dominant degree of 0.5. Therefore, it is possible to genetically improve the moisture resistance of wheat by reasonably matching the early selection of parents and offspring
