Predicting yield of individual field-grown rapeseed plants from rosette-stage leaf gene expression
Fig 5
Predictive power of early rosette areas for yield phenotypes.
In each subplot, median test R2 values are plotted for lme models predicting the given phenotype from early rosette areas v2 (14–42 DAS, x-axis). Only mature phenotypes that can be predicted from rosette area (42 DAS) with a median test R2 > 0.1 are shown. Blue lines are ordinary least-squares linear regressions, with shaded areas indicating 95% confidence intervals on the trendline. Most phenotypes exhibit a rather dichotomous median test R2 profile with rosette areas v2 from 14 to 28 DAS yielding substantially lower median test R2 values than rosette areas v2 from 32 to 42 DAS. Accordingly, linear model fits at 28 and 32 DAS are often poor.
