Identification of QTLs influencing combustion quality in Miscanthus sinensis anderss. II. Chlorine and potassium content

Chlorine and potassium content are important traits related to combustion quality of Miscanthus species. These traits were analysed in a cross between F(1.1) and F(1.7) entries of Miscanthus sinensis Anderss, both lines offspring of the cross between MS-90-2 and MS-88-110. Quantitative trait locus (QTL) analyses were performed on a previous linkage map constructed with the offspring cross mapping strategy. The mapqtl 4.0 package was used to perform QTL analyses. Six potential QTLs were detected with data collected over a 2-year period. Of these, four were associated with chlorine and two with potassium. These results could be used as an initial step to develop a marker-aided selection programme for biomass with low mineral content.
