Theses & Dissertations Open Access Resistance to the spotted stem borer and African maize stem borer in tropical maize S.W. Munyiri In sub-Saharan Africa (SSA), maize (Zea mays L.) is the staple food for about 50% of the population. Lepidoptera stem borers pause major threats to sustained food sufficiency in SSA where they cause annual yield losses of 15% and particula… RUF-35525 2014 CC BY 4.0 29 Sep 2015

Working Document Series Open Access Grain filling patterns of CIMMYT early maize inbred lines R. Edema · E. Gasura · P. Gibson · P. Okori +2 more Despite the ability of early maize to escape drought and provide food early, it yields 20-30% less than late maize. The challenge is to increase yield while maintaining earliness. A study is ongoing at CIMMYT, Harare to determine whether g… RUF-34614 2010 CC BY 4.0 8 Sep 2015
Working Document Series Open Access Genetic variation of Zambian maize inbred lines commonly used in breeding Richard Chanda · C. Mungoma · M. Mwala · K. Mwansa +1 more 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 inbr… RUF-34610 2010 CC BY 4.0 8 Sep 2015
Working Document Series Open Access Characterization of a diverse set of maize germplasm for resistance to infection by Aspergillus flavus and accumulation of aflatoxin G. Asea · D.B. Kwemoi · P.
