一组114重组自交系的'国际小麦族绘图倡议'映射人口在1997年，1998年，1999年和2000年的季节几个环境下生长。研究了20个形态性状（颖壳色、芒色、蜡质、叶片直立度、花序梗长）、农艺性状（出穗时间、开花时间、灌浆时间、穗长、株高、倒伏、粒数、千粒重、穗粒重、籽粒蛋白质含量、抗寒性）和抗病性状（白粉病、条锈病、叶锈病、镰刀菌）。并不是所有的特征都在每个实验中评分。共检测到210个LOD阈值大于2.0的QTL（次要QTL），其中64个LOD阈值大于3.0（主要QTL）。在不同的试验中，QTL常常在相似的位置上被检测到。本文还讨论了所检测到的QTL的同源性和同源性关系，以及在小麦或其他小麦族成员中已经描述的决定相同性状的主效基因或QTL。
A set of 114 recombinant inbred lines of the 'International Triticeae Mapping Initiative' mapping population was grown during the seasons 1997, 1998, 1999 and 2000 under several environments. Twenty morphological (glume colour, awn colour, waxiness, leaf erectness, peduncle length), agronomical (ear emergence time, flowering time, grain filling time, ear length, plant height, lodging, grain number, thousand-grain-weight, grain weight per ear, grain protein content, winter hardiness) and disease resistance (powdery mildew, yellow rust, leaf rust, fusarium) traits were studied. Not all traits were scored in each experiment. In total 210 QTLs with a LOD threshold of >2.0 (minor QTLs) were detected of which 64 reached a LOD score of >3.0 (major QTLs). Often QTLs were detected in comparable positions in different experiments. Homologous and homoeologous relationships of the detected QTLs, and already described major genes or QTLs determining the same traits in wheat or other Triticeae members, are discussed.
