Abstract: The bread waste is one of the important socio-economic's issues country now, the urgent need is feeling to improve the wheat quality. Therefore, using the methods of farming and breeding is necessary to improve the quality of this strategic product. As a result, tests of quality's traits in wheat promising lines in Isfahan climate took place. In this study, the choice 17 advanced lines of compare the performances,s experiments, an experiment was conducted for two consecutive cropping (2011-2012) at cultural experiment and research centre in Isfahan located in Kabutar Abad region. Randomized complete block designs with 3 replications were compared with Spring variety (for control). Traits including: 1000 grain weight, hectolitre weight, protein content, Zeleny sedimentation rate, bread volume, grain moisture content, grain hardness, water absorption, falling number, percentage of dry gluten, gluten index, sedimentation rates were SDS.The results of the combined analysis of variance qualitative characteristics,s for two consecutive cropping showed that treatments with compare together and control variety had significant influence in 1% probability.Correlation coefficients of two years showed that the compound test significant positive correlation within grain hardness index and protein content, wet gluten and dry deposition rates of SDS. Also, significant positive correlation with the percentage of protein content of dry gluten. In view of the high correlation with protein content of dry gluten (quantity). However, grain hardness and relatively high correlation with SDS sedimentation as an important measure of protein quality. Therefore, the test results of dry gluten grains can be tough to choose in order to improve the quality of wheat bread may be used.
