Evaluation of Striga-resistant Early Maize Hybrids and Test Locations under Striga-infested and Striga-free Environments
Emergence of several seed companies in the West Africa sub-region during the last decade has necessitated intensified efforts towards hybrid development and extensive testing. The objectives of the present study were to evaluate selected Striga-resistant maize (Zea mays L.) hybrids for grain yield and stability of performance based on multiple traits. Thirty Striga-resistant single–cross maize ...
متن کاملPrimary Haustorial Development of Striga asiatica
Hood, M. E., Condon, J. M., Timko, M. P., and Riopel, J. L. 1998. Primary haustorial development of Striga asiatica on host and nonhost species. Phytopathology 88:70-75. the host (sorghum) roots and advance into the cortex occurred within 24 to 48 h of inoculation. Penetration of the endodermis by the developing endophyte was delayed for 72 to 96 h after initial contact. However, upon penetrati...
متن کاملPhenetic relationships among different races of Striga gesnerioides (Willd.) Vatke from West Africa.
Striga gesnerioides is a root hemiparasite that primarily parasitizes dicotyledonous species, including cowpea (Vigna unguiculata L.) and other legumes. Based on the differential resistance response of various cultivars, landraces, and breeding lines, it has been proposed that several distinct races of cowpea-parasitic S. gesnerioides exist in West Africa. In this study, we used amplified fragm...
متن کاملGenetic variation and host–parasite specificity of Striga resistance and tolerance in rice: the need for predictive breeding
The parasitic weeds Striga asiatica and Striga hermonthica cause devastating yield losses to upland rice in Africa. Little is known about genetic variation in host resistance and tolerance across rice genotypes, in relation to virulence differences across Striga species and ecotypes. Diverse rice genotypes were phenotyped for the above traits in S. asiatica- (Tanzania) and S. hermonthica-infest...
متن کاملStriga Biocontrol on a Toothpick: A Readily Deployable and Inexpensive Method for Smallholder Farmers
Striga hermonthica (witchweed) is a parasitic weed that attacks and significantly reduces the yields of maize, sorghum, millet, and sugarcane throughout sub-Saharan Africa. Low cost management methods such as hand weeding, short crop rotations, trap cropping, or conventional biocontrol have not been effective. Likewise, Striga-tolerant or herbicide-resistant maize cultivars are higher yielding,...
