Meta-QTL (MQTL) analysis is a robust approach for genetic dissection of complex quantitative traits. Rice varieties adapted to non-flooded cultivation are highly desirable in breeding programs due to the water deficit global problem. In order to identify stable QTLs for major agronomic traits under...

Meta-QTL (MQTL) analysis for drought tolerance was undertaken in bread wheat to identify consensus and robust MQTLs using 340 known QTLs from 11 earlier studies; 13 MQTLs located on 6 chromosomes (1D, 3B, 5A, 6D, 7A and 7D) were identified, with maximum of 4 MQTLs on chromosome 5A. ...
The approach given by [99] was used to predict the MQTL on the chickpea genome as all of the chromosomes had more than 10 reported QTL. In this study, a total of 59 MQTL were predicted for a collective tolerance towards heat, cold, drought, and salinity stress from a total of 1158 Q...
Based on the criteria defined by Löffleret al.8to consider a MQTL for marker assisted breeding, i.e: small supporting intervals of the MQTLs, high number of initial QTLs and high PVE of the initial QTLs, eight root MQTLs, the “Breeding MQTLs”, were selected (Table3). Firstly, sev...
The results showed that 29 MQTL (each MQTL comprising two to six initial QTL) were projected on chromosomes 1 to 8. Six MQTL located on chromosomes 3 and 4 were recommended to use for improving ER resistance in a marker assisted selection (MAS) program. Meta-analysis also indicated that ...
The usefulness of our approach is illustrated on published QTL detection results of flowering time in maize. Finally, MetaQTL is freely available at urlhttp://bioinformatics.org/mqtl/url./p 展开 关键词: Genetic Markers Chromosome Mapping Sequence Alignment Sequence Analysis, DNA Quantitative Trait ...
析,分别在15条染色体上获得30个与纤维品质相关的MQTL。 上述结果表明,通过筛选不同来源的纤维品质性状QTL或者在不同遗传背景中能共同表达的 QTL,采用图谱映射和元分析的方法挖掘和寻找一致性QTL,可为图位克隆和分子标记辅助育种提 供重要依据。 关键词:棉花;纤维品质性状;遗传图谱;QTL;Meta分析 ...
QTL hotspots were further analyzed for mQTL within the hotspots using Biomercator V3 software. The ratio of QTL between the two population types was proportional yet differences in hotspot type and placement were observed between the two population types. However, on some chromosomes QTL clusters and...
According to our results breeders can in future (1) choose parents for crossing not comprising the same resistance loci or QTL intervals, (2) exploit new MQTL, and (3) select markers of some of these MQTL to be used in marker-assisted selection....
