两个收获年份小麦游离天冬酰胺浓度差异很大。73个商品小麦品种丙烯酰胺形成电位（AFP）的大范围变化。8个品种持续低AFP，其中7个为软型，但如果硫供应不足，使用低AFP品种的好处就会失去。选择低AFP的品种仅仅是基于它们是柔软的，这将是简单的。有关游离天冬酰胺浓度的信息应在品种发布时提供。游离天冬酰胺浓度是谷物中丙烯酰胺形成潜力的决定因素，研究人员于2011-2012年和2012-2013年在英国的田间试验中测量了小麦籽粒中的游离天冬酰胺浓度。2012年有25个品种，2013年有59个品种，其中11个品种参加了两次试验。试验分为两组，每组一半加硫，另一半不加硫。硫饲小麦游离天冬酰胺品种平均值（mmol / kg） 2011-2012年为1.521 ~ 2.687,2012-2013年为0.708 ~ 11.29。8个品种的游离天冬酰胺浓度一直很低。不同品种对硫的反应不同，2012-2013年游离天冬酰胺含量比2011-2012年高得多。鉴于某些小麦品种的商业寿命较短，因此，在品种上市时应提供游离天冬酰胺浓度的信息。
Widely differing free asparagine concentration in wheat from two harvest years. Wide range of acrylamide-forming potential (AFP) in 73 commercial wheat varieties. Eight varieties identified with consistently low AFP, seven of them soft types, but benefit of using a low AFP variety is lost if sulphur supply is inadequate. Selecting varieties for low AFP solely on the basis of them being soft would be simplistic. Information on free asparagine concentration should be available at variety launch. Free asparagine concentration, which is the determining factor for acrylamide-forming potential in cereals, was measured in grain from wheat grown in field trials in the United Kingdom in 2011–2012 and 2012–2013. There were 25 varieties in 2012 and 59 in 2013, with eleven present in both trials. The trials were split-plot, with half of each plot supplied with sulphur and the other half not. The varietal means (mmol per kg) for free asparagine in the sulphur-fed wheat ranged from 1.521 to 2.687 in 2011–2012 and 0.708 to 11.29 in 2012–2013. Eight varieties were identified as having consistently low free asparagine concentration. There was a differential response of varieties to sulphur, and much higher levels of free asparagine in 2012–2013 versus 2011–2012. Given the short commercial lifespan of some wheat varieties, it is concluded that information on free asparagine concentration should be made available when a variety is launched.
