“…The IITA's maize breeding programme initiated Striga research in Nigeria in 1982 and sources of horizontal resistance (tolerance) were discovered from the IITA inbred lines and hybrids in 1983 (IITA 1983;Kim et al 1985bKim et al , 1987. The initial efforts were devoted to developing an infestation technique in the laboratory and greenhouses (IITA 1985).…”

“…An individual maize variety must confer an adequate level of stability against major biotic and abiotic problems as well as providing a high yield potential. International centres and national programmes recommend maize varieties conferring streak resistance (SR) to African farmers (Kim et al 1987). The varieties must be acceptable to the farmers' preference (e.g.…”

“…Searching for a high level of complete resistance against parasites such as Striga and Orobanche species based on parasitic plants that have emerged has contributed greatly to delaying the development of a sustainable control package based on horizontal resistance (Kim 1995b (Kim et al 1985b(Kim et al , 1987(Kim et al , 1992Kim 1991bKim , 1994aKim and Winslow 1991). The grain yield was best correlated with the host plant Striga damage symptoms (r=-0.62) (p < 0.01 with n = 399).…”

Seed companies have marketed these hybrids in Nigeria and neighbouring countries since 1985 and farmers who grew these hybrids with moderate (60 kgha -I) and high (120 kgha -I) levels of nitrogen application do not face Striga problems any more.…”

Horizontal resistance: core to a research breakthrough to combat Striga in Africa

The parasitic flowering plants, Striga species, represent the largest biological constraint to cereal and legume crop production in sub-Saharan Africa. Eighty-three percent of Striga worldwide (35 species) occurs in Africa. Among them, Striga hermonthica causes the greatest damage. The IITA's scientists began research on breeding maize for horizontal resistance to Striga in 1982. By 1995 a comprehensive approach to combat Striga on maize had been developed and demonstrated. This included the development of a simple field infestation technique, the discovery of durable resistance genes, genetic studies of resistance genes and the formation of many resistant varieties (hybrids and synthetics) with high grain quality, high grain and stover yields and a combined resistance to major biotic and abiotic stresses. Multilocation testing and subsequent seed multiplication of the resistant varieties was carried out by national programmes in Benin, Burkina Faso, Cameroon, the Ivory Coast, Ethiopia, Ghana, Nigeria, and Togo. Striga-resistant maize varieties show horizontal resistance not only to S. hermonthica, but also to another species, Striga asiatica. Based on the results of a 15year research, an integrated approach using resistant varieties and cereal-legume intercropping or rotation is recommended as a sustainable and permanent solution to combat Striga in Africa. This horizontal resistance package, with a combined resistance to other biotic stresses, could be applicable not only to Striga problems in other crops such as sorghum, millet, rice and cowpea, but also to other parasitic weeds, such as Orobanche species. This paper reviews and discusses why, approximately a century's research work on parasitic weeds, has not led to a major research breakthrough.

“…The six released germplasm lines were derived from biparental crosses and backcross populations involving tropical elite African inbred lines (1368, 4001, and KU1414-SR) from the IITA [11] with some levels of resistance to aflatoxin production [6] and U.S. inbred lines GT-MAS:gk, MI82, and Mp420, with proven resistance to aflatoxin contamination [2,3,12,13] as parents. TZAR101 was derived from a cross of 1368 to GT-MAS:gk, while TZAR102 and TZAR103 were extracted from a cross of the same tropical inbred line (1368) to MI82.…”

Evaluation of African-Bred Maize Germplasm Lines for Resistance to Aflatoxin Accumulation

et al. 2016

Abstract:Aflatoxins, produced by the fungus Aspergillus flavus, contaminate maize grain and threaten human food and feed safety. Plant resistance is considered the best strategy for reducing aflatoxin accumulation. Six maize germplasm lines, TZAR101-TZAR106, were released by the International Institute of Tropical Agriculture-Southern Regional Research Center (IITA-SRRC) maize breeding collaboration for use in African National Programs and U.S. maize breeding programs. The present investigation was conducted to evaluate aflatoxin reduction by these lines in a U.S. environment. Results demonstrate significant aflatoxin reduction by IITA-SRRC lines in a U.S. aflatoxin-conducive environment (at Mississippi State University). Further testing in different locations and environments is needed to further evaluate the potential usefulness of these germplasm lines.
