identification of new maize inbred lines with resistance to striga hermonthica (del.) benth.
striga hermonthica is a noxious, obligate hemi-parasite of cereal grasses that causes severe grain yield loss in susceptible maize cultivars in africa. the development of host plant resistance is one of the most practical stiga control strategies. in this study experiments on 36 maize inbred lines were conducted in pots and in field during the two rainy seasons of 2009 at kibos and alupe statio...
متن کاملGenome-Wide Association Study and QTL Mapping Reveal Genomic Loci Associated with Fusarium Ear Rot Resistance in Tropical Maize Germplasm
Fusarium ear rot (FER) incited by Fusarium verticillioides is a major disease of maize that reduces grain quality globally. Host resistance is the most suitable strategy for managing the disease. We report the results of genome-wide association study (GWAS) to detect alleles associated with increased resistance to FER in a set of 818 tropical maize inbred lines evaluated in three environments. ...
متن کاملEffects of soil pasteurisation and soil N status on severity of Striga hermonthica (Del.) Benth. in maize
The nature of interrelationships between soil pasteurisation, and increased soil N content, on the severity of Striga hermonthica infection in maize was studied in pot experiments in the screen-house. An initial experiment revealed that there was no significant difference in amount of S. hermonthica infection in maize grown in potted soil collected from Bida (98050N, 68010E) and Ibadan (78170N,...
متن کاملDetermination of levels of Striga germination Stimulants for maize gene bank accessions and elite inbred lines
Parasitism by Striga hermonthica (Del) Benth is a severe constraint in maizeproduction in sub-Saharan Africa. Varying levels of tolerance to Striga attack havebeen identified and exploited in breeding programs of several crops. However, thelevel and stability of the tolerance is generally unacceptable in field-practice. Onlylimited exploration has been undertaken among the farmers’ landraces to...
متن کاملEffect of Seed Priming on Early Development of Sorghum (Sorghum bicolor L. Moench) and Striga hermonthica (Del.) Benth
Striga hermonthica is an obligate, root parasite, that limits cereal production in sub-Saharan Africa. Successful control depends on eliminating its seed reserves in soil, thereby preventing parasitism. Two experiments were conducted to evaluate the effects of salinity on germination traits and seedling growth of sorghum (cultivar Wad Ahmed) and S. hermonthica. The experiments were conducted in...
