摘要
本研究用来自不同遗传背景、品质差异较大的14个品种(系),在四川6个主要麦区布点,连续2年进行基因×环境互作试验,研究面团流变学特性在四川生态区的变异。经相关分析,产量与吸水率、形成时间、稳定时间和粉质评价值呈极显著负相关。面团特性在地点间呈一定变化趋势。试验结果经聚类分析把参试点分为2个麦区:第一类优质区为成都、宜宾、井研、简阳,但简阳对品质的表达不稳定;第二类普通麦区为资中和阆中。有4个品种在优质点的面团稳定时间大于7min,达到国家专用小麦品种品质的强筋标准。本研究表明在四川部分麦区能生产出优质小麦。
Fourteen varieties/lines with different quality derived from different genetic background were planted for G×E testing at 6 locations for 2 years.The correlations between yield and water absorption,dough development time,dough stability time,and farinograph quality number were all negative and highly significant.There was a tendency about change of dough character at different locations.Locations were clustered into two types,namely,high quality region inculding Chengdu site,Yibin site,Jinyan site and Jianyang site,and common quality region including Zizhong site and Langzhong site.But the quality was not stable at Jianyang site.Four varieties,of which dough stability time were over 7 min,reached national standard about wheat varieties for special end-use.The results showed that high quality wheat could be produced in some regions in Sichuan province.
