Enhancing Drought Tolerance and Striga hermonthica Resistance in Maize Using Newly Derived Inbred Lines from the Wild Maize Relative, Zea diploperennis

Agronomy, 2021
Recurrent drought and Striga hermonthica (Del.) Benth parasitism constrains maize production in sub-Saharan Africa (SSA). Transfer of resistance genes from wild relatives can improve resistance to drought and Striga in tropical maize.

Responses of parasitoids to volatiles induced by Chilo partellus oviposition on teosinte, a wild ancestor of maize [PDF]

, 2015
Maize, a genetically diverse crop, is the domesticated descendent of its wild ancestor, teosinte. Recently, we have shown that certain maize landraces possess a valuable indirect defense trait not present in commercial hybrids.

Evolutionary relationships in the genus Zea: analysis of repetitive sequences used as cytological FISH and GISH markers

Genetics and Molecular Biology, 2000
The present study is a revision of our work on evolutionary cytogenetics of the genus Zea, including several new experiments which give a deeper insight into the nature of the DNA sequences involved in telomeric regions of Zea luxurians.

Genomic in situ hybridization analysis for identification of introgressed segments in alloplasmic lines from Zea maysxZea diploperennis [PDF]

Hereditas, 2003
In this study, the tested four alloplasmic inbred lines, a2-4, a2-5, b1-1 and b2-1 were propagated from the same disease resistant individual in the parthenogenetic progenies of Zea mays L. cv. Lu 9 x Zea diploperennis (DP). All the lines except a2-5 were resistant to Helminthosporium turcium Pass and H. maydis Nisik.

Genetic Improvement in Resistance to Striga in Tropical Maize Hybrids

Crop Science, Volume 59, Issue 6, Page 2484-2497, November-December 2019., 2019
ABSTRACT Striga hermonthica (Del.) Benth parasitizes maize (Zea mays L.) in sub‐Saharan Africa, causing yield losses of up to 100% under severe infestation. Hybrid maize breeding for polygenic resistance to Striga has been undertaken at the International Institute of Tropical Agriculture (IITA) since the 1980s.
