摘要

With the increasing demands in crop breeding for novel traits,plant research community faces to quantitatively analyze the structure and function of large numbers of plants. A clear goal of highthroughput phenotyping is to bridge the gap between genomics and phenomics. In this study,we obtained 106 traits from a maize recombinant inbred line population across 16 development stages using the automatic phenotyping platform.The results showed that the exponential model had better predication ability for biomass accumulation,even in the early growth stage. QTL mapping with high density genetic linkage map was used to uncover the genetic basis of these complex agronomic traits,and have identified 2265 QTLs for all investigated traits. We also conduct the traits-loci network analysis and 3 house-keeping loci were detected in the hub points for 2 traits. These results reveal the dynamic genetic architecture of maize plant growth thus enhance maize ideotype breeding in the near future.
