From: Genetic trends in CIMMYT’s tropical maize breeding pipelines
(a) Average grain yield in each of the breeding pipelines by individual management practices in the first year; genetic trend across product profiles presented in (b) kg ha−1 yr−1 and (c) % yr−1. Non-significant trends are not presented. Abbreviations: Drt, drought; HYP, high yield potential; LYP, low yield potential; Med, medium; Opt, optimum; RS, random stress; VPD, vapour pressure deficit; W, white; Y, yellow.
