Maize (Zea mays L.) production in west and central Africa (WCA) is constrained by the parasitic weed Striga hermonthica (Del.) Benth and recurrent drought. Two early maize populations, TZE-W Pop DT STR C0 (white) and TZE-Y Pop DT STR C0 (yellow), developed from diverse genetic backgrounds, were s...

The potential maize (Zea mays L.) yield in the savannas of West and Central Africa (WCA) is constrained by Striga hermonthica (Del.) Benth. parasitism. Field trials at Ferkessedougou, Côte d'Ivoire; Abuja, Nigeria; and Mokwa, Nigeria, in 2002, and at Mokwa and Abuja in 2004, evaluated the perform...

Agronomic performance of striga resistant early-maturing maize varieties and inbred lines in the savannas of West and Central Africa
Availability of extra-early maize cultivars has facilitated the expansion of maize production into savannas of West and Central Africa (WCA). Fifty-six extra-early maize cultivars of three breeding eras;1995 to 2000, 2001 to 2006, and 2007 to 2012 were evaluated for 2 yr under 24 multiple-stress ...

An extra-early maturing white-grained, flint/dent maize (Zea mays L.) population, TZEE-W Pop STR C4 (Reg. No. GP-576; PI 657704), has been developed at the International Institute of Tropical Agriculture. The population has moderate levels of resistance to Striga hermonthica (Del.) Benth. It was ...

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 ...

Assessment of reliability of secondary traits in selecting for improved grain yield in drought and lownitrogen environments
A major problem that usually confronts the breeder is ensuring that there is sufficient genetic variability in a population for the trait being improved because this determines the breeding schemes to use for improvement and whether or not sufficient progress could be made. Three hundred full-sib...
