Genotype × environment interactions complicate selection of superior genotypes for narrow and wide adaptation. Eighteen tropically-adapted maize cultivars were evaluated at six locations in Nigeria for 2 yr to (i) identify superior and stable cultivars across environments and (ii) assess relation...

Hybrid development is enhanced by the assessment and understanding of genetic diversity and distance within inbreds. One hundred and fifty hybrids derived from 30 early-maturing inbreds plus six checks were evaluated at three locations in Nigeria for 2 years to assess their performance under drou...

Grain yield of maize (Zea mays L.) has low heritability under low soil nitrogen (low N) and drought, necessitating the use of secondary traits with strong associations with yield forselection. A base index involving anthesis–
silking interval, plant and ear aspects, earsper plant, and stay green ...
