摘要:
2000/2001年度全国冬小麦7个试区79个参试品种(系)品质性状测试结果表明:当前我国冬小麦品种各品质性状的平均水平为蛋白质含量141 g/kg,沉淀值27.1 mL,面粉吸水率60.8%,面团形成时间2.7 min,面团稳定时间3.1 min,软化度117 BU,粉质评价值44。各品质性状在地域表现上都有明显的北高(优)南低(差)趋势。综合品质性状达到强、中、弱筋小麦品质标准的分别有3,14和9个品种,其中北部旱地组强筋1个、中筋3个,北部水地组强筋1个、中筋3个,黄淮旱地组强筋1个、中筋2个、弱筋1个,黄淮北片组中筋1个,黄淮南片组中筋5个、弱筋1个,长江中下游组弱筋2个,长江上游组弱筋5个。面筋蛋白质质量差是我国冬小麦当前品种品质的主要问题。

Status quo and problem of winter wheat quality in China
Abstract:
The quality characteristics of 79 winter wheat varieties(lines),sampled from 7 wheat region experiment areas in China,have been analysised.The results are as followings:protein content 141 g/kg,sedimentation volume 27.1 mL,water absorption 60.8%,development time 2.7 minutes,stability 3.1 minutes,degree of softening 117 BU,valurimeter value 44.The north wheat varieties quality is better than the south’s.There are 3,14 and 9 wheat varieties reach the quality standard of high quality,high gluten strength,middle gluten strength and low gluten strength respectively.The north dry areas have 1 high gluten strength and 3 middle gluten strength and high quality varieties.The north irrigated area have 1 high gluten strength and 3 middle gluten strength high and quality varieties.The dry of Huanghuai areas have 1 high gluten strength,2 middle gluten strength and 1 low gluten strength and high quality varieties.The north of Huanghuai areas have 1 middle gluten strength and high quality variety.The south of Huanghuai areas have 5 middle gluten strength and 1 low gluten strength high quality varieties.The middle and lower reaches of Changjiang River areas have 2 low gluten strength and high quality varieties.The upper reaches of Changjiang River areas have 5 low gluten strength and high quality wheat varieties.The main problem on current wheat varieties quality is the poor gluten protein quality.
