Analysis on Main Quality Characters in New Introducing Wheat Varieties

To understand the characters of the importing wheat varieties and use them reasonably,28 Hungary wheat varieties were tested,and their quality characters were studied.The result showed that Hungary wheat varieties have good performance in term of protein content,water absorption,sedimentation value,developing time and stability time.The average separately is 16.6%,59.5%,40 mL,9.37 min and 10.24 min,but wet gluten content is low.Order of the variation coefficient in main quality characters is: mixing tolerance index stability time developing time valorimeter value sedimentation value wet gluten content protein content water absorption.The variation coefficient of protein content and water absorption is small,so protein content and water absorption is stable,the variation coefficient of stability time and developing time is big,so chance rang is wide.Correlation analysis indicated that the correlation during sedimentation value with water absorption,stability time,developing time,valorimeter value reached to more positive relation,the correlation during wet gluten content with protein content,mixing tolerance index reached to more positive relation.The result of clustering analysis indicated that 28 Hungary wheat Varieties were clustered into four groups based on main quality characters.The group Ⅰ and the groupⅡhad better quality characters,the groupⅢand the groupⅣ had bad quality characters.
