对芒属芒这两个品系都是MS-90-2和MS-88-110杂交的后代。本研究的目的是确定影响产量及其构成因素的QTL，为建立小麦分子标记辅助选择（MAS）提供依据。中国的。QTL分析使用以前的连锁图的基础上RAPD标记，这是使用一种新的作图策略命名为“后代杂交”，是有用的映射在森林和果树构建。使用MapQTL 4.0软件包进行QTL分析。在两年的分析中检测到20个潜在的QTL。其中，6个与产量相关，8个与茎产量相关，2个与叶产量相关，4个与最高产量相关。这些结果构成了开发用于生物质生产的MAS程序的第一步。
Yield and its components (stem-, leaf- and top-yield) were analyzed in a population derived from the cross between F1.1 and F1.7 entries of Miscanthus sinensis Anders. Both lines are offspring of the cross between MS-90-2 and MS-88-110. The aim of this work was to identify QTLs for yield and its components suitable to develop a Marker Aided Selection (MAS) program in M. sinensis. QTL analyses were performed using a previous linkage map based on RAPD markers which was constructed using a new mapping strategy named 'offspring cross' that is useful for mapping in forest and fruit trees. The MapQTL 4.0 package was used to perform QTL analyses. Twenty potential QTLs were detected over two years of analyses. Out of these, 6 were associated with yield, 8 with stem- yield, 2 with leaf- yield and 4 with top-yield. These results constitute an initial step to develop a MAS program for biomass production.
