Relationship between average root hair length (mm) and specific rhizosheath weight (mg cm–1 root) for contrasting root hair genotypes grown in the field in sandy loam and clay loam soils for two subsequent years: 2017 (A–D) and 2018 (E–H). Two sampling campaigns were done in 2017 (24 and 56 d from sowing) and 2018 (19 and 49 d from sowing). The coefficient of determination R2 and corresponding P-values are reported upon fitting with equation y = y0 + a × x.
