| Abstract: |
| The relationships between quality and yield characters of wheat varieties from regional trials in Huanghui winter wheat area were studied. The results indicated: there were no significant contradiction between yield and test weight, hardness, wet gluten and milling extraction, therefore, these quality characters could be improved simultaneously with high yield; there usually were significant contradictions between yield and protein content and sedimentation value, thus enhancing grain yield often associated with these quality characters becoming poor, but there were no significant contradiction between them in some area and some varieties; thousand grain weight, grain number per spike and grain weight per spike were negatively correlated with the most quality characters; yield of individual plant and spikes per 666. 7 m2 usually were positively or little negatively correlated with the most quality characters. Thus, if yield of individual plant and spikes per 666. 7 m2 were used as selection criterions in early generations of breeding, high grain yield and high quality may be coordinated. There were no correlation between yield components and farinogram. |
