Selecting Informative Traits for Multivariate Quantitative Trait Locus Mapping Helps to Gain Optimal Power
A major consideration in multitrait analysis is which traits should be jointly analyzed. As a common strategy, multitrait analysis is performed either on pairs of traits or on all of traits. To fully exploit the power of multitrait analysis, we propose variable selection to choose a subset of informative traits for multitrait quantitative trait locus (QTL) mapping. The proposed method is very u...

20 A major consideration in multitrait analysis is which traits should be jointly analyzed. As a 21 common strategy, multitrait analysis is performed on either pairs of traits or on all of traits. To 22 fully exploit the power of multitrait analysis, we propose variable selection to choose a subset of 23 informative traits for multitrait quantitative trait locus (QTL) mapping. The proposed meth...
متن کاملQuantitative trait loci mapping of panicle traits in rice
In this study 90 individuals of recombinant inbred lines (RILs) were developed by crossing subspecies of japonica rice cultivar, ‘Nagdong’ and an indica type cultivar, ‘Cheongcheong’. These individuals were used to identify the quantitative trait loci of panicle traits using SSR markers. A genetic linkage map was constructed using one hundred fifty four simple sequence repeat ...

متن کاملEnhanced efficiency of quantitative trait loci mapping analysis based on multivariate complexes of quantitative traits.
An approach to increase the efficiency of mapping quantitative trait loci (QTL) was proposed earlier by the authors on the basis of bivariate analysis of correlated traits. The power of QTL detection using the log-likelihood ratio (LOD scores) grows proportionally to the broad sense heritability. We found that this relationship holds also for correlated traits, so that an increased bivariate he...
