Yield and combining ability of temperate ex-PVP introgressed and tropical maize under contrasting moisture regimes.

PloS one - 1 Jan 2026

Abstract excerpt

Low grain yield and recurrent drought remain major constraints to maize production in Sub-Saharan Africa (SSA), underscoring the urgent need for hybrids with improved resilience. The use of ex-PVP (expired Plant Variety Protection) temperate maize lines is important to improve yield potential and genetic diversity in tropical adapted lines. In this study, 15 temperate introgressed lines and 6 tropical lines were...
