| [目的]明确黄淮南片当前种植小麦品种的品质状况及存在问题,为我国黄淮南片小麦品质育种和品种利用提供理论与技术依据.[方法]对黄淮南片82个小麦品种(系)的容重、蛋白质含量、湿面筋、沉降值、吸水率、形成时间、稳定时间、最大抗延阻力和拉伸面积等品质性状进行测定与分析.[结果]黄淮南片小麦品种(系)各品质性状的平均水平分别为:容重797.6 g/L,蛋白质含量144 g/kg,湿面筋31.3%,沉降值33.2 mL,面粉吸水率59.5%,形成时间3.3 min,面团稳定时间4.6 min,最大抗延阻力255.8 EU,拉伸面积55.2 cm2;根据专用小麦品质标准综合评定,黄淮南片82个供试小麦品种(系)中,品质性状达到强筋的有7个,仅占8.54%,中筋的有41个,占50%,弱筋的有4个,占4.88%.[结论]而筋强度差、稳定时间短、拉伸面积小是黄淮南片小麦品种(系)普遍存在的突出问题.因此育种工作者应在提高产量的同时,加强对沉降值和面团稳定时间及拉伸面积的选择,以满足生产和加工对优质、强筋小麦的需求. |

| Abstract: |
| 【Objective】 The study was done to provide technical and theoretical foundation for wheat quality breeding,and to make clear the current situation and problems of wheat varieties or lines in southern area of Huanghuai.【Method】 The quality properties of 82 winter wheat varieties（lines），sampled from wheat region experiment,the weight,protein,wet gluten,sedimentation,water absorption,development time,stability time,maxium resistance and area were analyzed.【Result】 The results were as follows：test weight 797.6 g/L,protein content 144 g/kg，wet gluten content 31.3%，sedimentation value 33.2 mL，water absorption 59.5％，development time 3.3 min,stability time 4.6 min，maxium resistance 255.8 EU,area 55.2 cm2 .only 7 wheat varieties(8.54%) reached the quality standard of the strong gluten wheat，4 wheat varieties(4.88%) met the low gluten strength and 50％varieties remained intermediate gluten strength.【Conclusion】 The main problem of current wheat varieties quality is the poor gluten protein quality，short dough stability and small area. Consequently，to suit the requirments of the high quality wheat for farming and food processing，breeding of wheat varieties should keep the increase of yield and enhance the selection of sedimentation value and dough stability. |
