摘      要：Ancherythroculter nigrocauda is a fish endemic to the upper areas of the Changjiang(Yangtze)River in *** trait locus(QTL)mapping is a powerful tool to identify potential genes affecting traits of economic importance in domestic *** this study,a high-density genetic map was constructed with 5901 single nucleotide polymorphism(SNP)makers by sequencing 92 individual fish from a F1 family using the specific-locus amplified fragment sequencing ***,48 QTLs for total length,body length,body height,and body weight were identified according to the high density of the genetic map with 24 LGs,a total length of 3839.4 cM,and marker spacing of about 0.82 *** QTLs explained 27.1%-49.9%of phenotypic *** results of this study suggest that major QTLs are responsible for the growth of ***,and these are potentially useful in comparative genomics research,genome assembly,and marker-assisted breeding programs for this species.
