Genetic variation of Zambian maize inbred lines commonly used in breeding
Abstract

In sub-Saharan Africa (SSA), breeders have the challenge of
developing high yielding maize hybrids that are adapted to
farmers’ conditions. This however requires knowledge on the
breeding value of elite maize germplasm. Ten (10) maize inbred
lines were grown under low nitrogen and optimal conditions at
Golden valley and Chilanga in Zambia. The randomized
complete block was used, with 2 row plots, 5.0m long and
replicated twice. The inbreds were planted at a spacing of
0.50m, with two plants left per station and 0.90m between rows.
Preliminary results for data collected under optimal conditions
at Golden Valley indicates that variation exists among the elite
germplasm tested. This offers opportunity for maize breeding
in Zambia to maximize heterosis. However, the variation will
be validated with testcross performance.
