黄淮麦区35份小麦种质资源品质性状比较分析

为了解黄淮麦区35份小麦种质资源的品质表现并为筛选合适的优质小麦资源提供参考，采用近红外分析仪对35份小麦种质资源的品质性状进行了分析。结果表明：品种间沉淀值、稳定时间和形成时间的差异较大，而容重、出粉率和吸水率的差异较小。蛋白质含量与湿面筋含量、形成时间、沉降值呈极显著正相关（正相关性最大r=0.97^**），容重与稳定时间、出粉率呈极显著正相关；湿面筋与稳定时间、形成时间、沉降值呈极显著正相关；稳定时间与形成时间、沉降值、出粉率呈极显著正相关。安徽、河南、山东、河北和江苏五个省份选育品种在沉降值、稳定时间和形成时间等品质性状上有显著差异。通过对全部品种各项指标进行筛查，综合容重、蛋白质含量、湿面筋含量以及稳定时间等品质因素，皖麦38、安农0419、郑麦366、山农0919、衡6061、扬麦23在本次试验中表现突出。

Comparative analysis of quality characters of 35 wheat germplasm resources in Huang-Huai Wheat Region

In order to understand the quality performance of 35 Wheat Germplasm Resources in Huang-Huai wheat region and provide reference for selecting suitable high quality wheat resources, the near infrared analyzer was used to analyze the quality characteristics of 35 wheat germplasm resources. The results showed that the differences of sedimentation value, stabilization time and formation time were large, while the differences of bulk density, powder yield and water absorption were small. Protein content was positively correlated with wet gluten content, formation time and sedimentation value (maximum positive correlation R = 0.97**), bulk density was positively correlated with stabilization time and flour yield; wet gluten was positively correlated with stabilization time, formation time and sedimentation value; stabilization time was positively correlated with formation time, sedimentation value and flour yield. There were significant differences on quality characters including sedimentation value, stable time and forming time among five provinces of Anhui, Henan, Shandong, Hebei and Jiangsu. Compared with others,Wanmai38,Annong0419,Zhengmai366,Shannong0919, Heng6061 and Yangmai23 have performed outstanding results based on the comprehensive quality including bulk density, protein content ,wet gluten content and stable time.
