Yield and combining ability of temperate ex-PVP introgressed and tropical maize under contrasting moisture regimes
Fig 2
Mean performance comparison of testcross hybrids from tropical and temperate-introgressed lines.
(A) Mean performance under well-watered (WW) and drought stress (DS) conditions compared using Student’s t-test. (B) Grain yield comparison under WW between hybrids derived from original tropical lines and their corresponding temperate-introgressed versions. The x-axis denotes the original tropical parental line used for introgression; TI_1–TI_5 represent the five temperate-introgressed derivatives.
