Abstract:

To explore the effects of mixed planting of different gluten strength wheat varieties on quality characteristics and yield traits, 'Jimai 44' and 'Jimai 23' were used as materials for field mixed sowing. The quality characteristics, food processing quality, and yield-related traits were studied. The results showed that the grain protein content of mixed culture exceeded 15.0% and was significantly higher than that of monoculture of 'Jimai 23' (T23). The wet gluten content, gluten index and dry gluten value were all higher than the lower value of monoculture. The development time, stability time, degree of softening and farinograph quality index were all significantly better than that of T23. The water absorption exceeded 63.0% and was higher than that of monoculture of 'Jimai 44' (T44), both reaching the level of strong gluten. The color, texture and crumb structure of bread core, the increased neck length and total score were not significantly different from T44, but were significantly better than T23. The appearance, hardness, viscoelasticity, smoothness and total score of noodles were not significantly different from those of monoculture, and taste was similar to that of T44, but the color was significantly different from that of T44. The qualities of both bread and noodles reached an excellent level. At the same time, the changes of yield traits such as maximum total number of stems, number of spikes per hectare, heading ratio and grain weight of plot were all higher than those of monoculture. In summary, the reasonable mixed culture of 'Jimai 44' and 'Jimai 23' at a ratio of 60-70 to 40-30 not only improved the quality characteristics and food processing properties but also increased the yield. The results could provide the scientific and technnological support for the production of special end-use flour by reasonable mixed planting.
