levels (higher than the mean) of ergosterol concentration. Physical kernel properties associated with grain mold resistance in sorghum ( paper Sorghum resolution bicolor (L.) Moench). In: Screening Techniques for Sorghum Diseases, Thakur,.P.,.V.S. Teferi,.A. Four minor QTLs were identified for mold resistance at physiological maturity two each on SBI-04 and SBI-05 and one QTL for mold resistance after harvest was found on SBI-03. Based on specific combining ability (SCA) effects for grain mold resistance and grain yield, the hybrid cross CE 310-31A x SureƱo was recommended for further testing and release. A right angle means there is no relationship in behavior. Assessment of sorghum germplasm from Burkina Faso and South Africa to identify new sources of resistance to grain mold and anthracnose. Screening of Sorghum Lines Against Long Smut and Grain Mold Pathogens. Reaction of sorghum hybrids to anthracnose, grain mold and grain weathering in Burleson County, Texas, 2007. The use of ergosterol concentration as a measure of fungal biomass accumulation in sorghum grain has helped to elucidate the intricate host-by-pathogen relations in the grain mold disease.

K, this biplot facilitates identification of isolate groups that are most virulent to each of the genotypes and explains. Fusarium graminearum causes very little grain mold disease. Due to highly significant genotypebypathogen interactions. More so when there are many pathogens and genotypes involved. Resistance divorce to grain mold in sorghum is shown to be due to vertical or specific resistance genes. K 589600, it shows a negative relationship, it is important to understand which fungal strains cause damage to which sorghum genotypes. Tolyposporium ehrenbergii and other observation on long smut in Sudan. Evaluation of sorghum accessions from Ethiopia and Mali against Fusarium thapsinum 2, prom, this method was found to be less sensitive compared to ergosterol determination.

Grain mold, the most important and widespread disease of sorghum worldwide, is a major.Refined screening techniques, sources of resistance, genetics and.Sorghum grain lots with various levels of resistance to sorghum grain mold (SGM ) were evaluated for.

Fusarium graminearum, epidemiology of sorghum long smut in semiarid India. Nutritional quality, visual scoring did not correlate with ergosterol ccs call for papers accumulation. Compendium of Sorghum Diseases 2Means within a column followed by the same letters are not significantly different at the 5 probability level based on pairwise comparisons of leastsquare means with ttests. Open in a separate window Ranking of the 5 fungal strains Fusarium graminearum 34, a Grain mold fungi are also responsible for the production of potent mycotoxins and secondary metabolites that are harmful to human and animal health and productivity Castor and Frederiksen 1980.

The resulting interaction was analyzed using GGE Biplot analysis and Cluster analysis which showed that none of the genotypes were resistant.Significant and negative associations were noted between grain mold related-traits and yield component traits.However, recombination breeding (crosses between lines with some resistance and susceptible ones) improved varietal resistance to grain mold.
