Correlations between agro-morphological traits.

Plots of the coefficients of correlation calculated between agro-morphological traits per pairs. For each graph 45 correlation coefficients associated to 45 pairs of agro-morphological traits obtained in different conditions or at different dates were compared among 188 pearl millet lines. The traits were measured in the field in Bambey in 2015 and 2016 with and without drought stress applied during 30 days from 21 days after sowing A. Plot comparing the coefficients without stress in 2015 and 2016 B. Plot comparing the coefficients with drought stress in 2015 and 2016. C. Plot comparing the coefficients with and without drought stress in 2015 D. Plot comparing the coefficients with and without drought stress in 2016.
