In addition, we calculated the community weighted mean values (CWMs) of the leaf and wood traits, i.e., the mean trait values across all individuals of a community.
Although we found a strong filtering of 17 functional traits, similar climate and soil conditions support communities differing greatly in mean trait values.
Trait-based approaches often rely on the tacit assumption that intraspecific trait variability (ITV) is negligible compared to interspecific variability, so that species can be characterized by mean trait values.
The mean trait values of the ILs were nearly the same as Hwaseong.
For the DH population, the mean trait values and GCA effect were used as input data.
For each of the BC populations, the mean trait values and SCA effect of the BC hybrids were used as input data.
We performed a GWAS to excavate the SNPs significant associations with all measured traits using 26,097 SNPs and the mean trait values of the 423 accessions.
Transgressive segregation that fell beyond the high or low mean of the two parents was observed, and the mean trait values of the ILs were nearly the same as those of Hwaseong.
A paired t-test was used to compare the performance of 57 rice varieties under control and cold treated conditions in Chuncheon based on mean trait values for DTH, CL, PN, SPP and PSS for each variety.
In the present study, temperature had a large effect on mean trait values in general, while nutrition influenced wing morphology.
Each drug treatment was assessed for its impact on the patterns of correlations across mean trait values or strains (see Suppl. Figures 5 7 in Supplement S1).
