Molecular Characterization of Genetic Diversity and Trait Association Analysis for Yield Improvement in Maize (Zea mays L.) Using SSR Markers

B. Vishnunanda Reddy, I. Sudhir Kumar, P. Shanthi, G. Prashanthi & S. K. Nafeez Umar · Journal of Advances in Biology & Biotechnology · 2026

A total of 11 maize inbred lines were crossed with 4 testers in a line × tester mating design (Kempthorne, 1957), generating 44 F₁ test crosses. These, along with 11 lines, 4 testers, and 5 checks (64 genotypes), were evaluated in a simple lattice design with two replications dur...
