BX‐feedback on wheat insect resistance and chlorophyll content. Wheat plants from cultivar Drifter and Fiorina were grown on ‘BX+’ and ‘BX−’ variants of Changins soil. (a) Caterpillar performance of Spodoptera littoralis fed with leaves of 5‐weeks‐old plants was measured after 4, 5 and 7 days of feeding; and (b) leaf chlorophyll content (SPAD values) was measured on 6‐weeks‐old plants. Data S5 documents the statistical analyses in detail. The LME (model: ~ day_feeding * condition [C] * wheat_line [WL], random factor = individual) for (a) and ANOVA (model: ~ condition [C] * wheat_line [WL]) for (b) results are reported next to the figure (significance code: p < .001***; p < .01**, p < .05*; p < .1 ‘.’; ‘n.s.’ = not significant) [Colour figure can be viewed at wileyonlinelibrary.com]
