Interactive 3D graphical visualization for abstract expression of QTL, epistasis and their environmental interactions for experimental populations was developed in framework of user-friendly software QTLNetwork (http://ibi.zju.edu.cn/software/qtlnetwork). Novel definition of graphical meta system and computation of virtual coordinates are used to achieve explicit but meaningful visualization. Interactive 3D graphical visualization for QTL analysis provides geneticists and breeders a powerful and easy-to-use tool to analyze and publish their research results.展开更多

A genetic linkage map was constructed based on 8 602 SLAF （specific-locus amplified fragment） markers, combine with the chatkiness traits of the tested lines. Four QTLs that related to chalkiness were detected using MapQTL 5 software, named qC-5a, qC-5b, qC-5c and qC-5d. The LOD threshold values of qC-5a, qC-5b, qC-5c and qC-5d were 4.02, 4.09, 3.94 and 4.1, respectively, explaining 11.6%, 11.8%, 11.2% and 11.8% of the observed phenotypic variance. All the four detected QTL alleles came from Iow-chalkiness parent V20B.展开更多
