Yield and combining ability of temperate ex-PVP introgressed and tropical maize under contrasting moisture regimes
Fig 3
Genetic variance components of testcross hybrids under contrasting moisture conditions.
(A) Proportional contribution of lines, testers, and line × tester interaction to total genetic variance for grain yield (GY), days to anthesis (AD), days to silking (SD), anthesis–silking interval (ASI), plant height (PH), ear height (EH), ear rot (ER), and gray leaf spot (GLS) under well-watered (WW) and drought stress (DS) conditions. (B) Proportion of additive (VA) and dominance (VD) genetic variance for grain yield and agronomic traits of 168 testcross hybrids under WW and DS conditions.
