Analysis of Meta-QTL and Candidate Genes Related to Tassel Branch Number in Maize
The tassel branch number is one of the important factors affecting yield and stress resistance in maize.In this study,188 QTLs for maize tassel branch number were integrated from 26 published papers using the IBM2 2008 Neighbors high-density maize genetic map.Meta-analysis was to obtain 14 Meta-QTLs(MQTLs).By comparing with homologous rice inflorescence genes,4 candidate genes related to tassel branch number were identi-fied,located on chromosomes 2,7 and 8.The analysis of Meta-QTLs candidate genes related to the number of tassel branches in maize can provide useful information for molecular marker-assisted breeding and gene cloning.
