Book Description
Seeds frequently are contaminated by seed-borne disease organisms not detected through routine laboratory tests for seed quality. Wherever Sorghum bicolor Moench is grown, the grain is subject to weathering and attack by many diseases. Fusarium moniliforme Sheldon is one of the most common pathogenic agents present in the sorghum area of adaptation and can damage the mature plant as well as increase seedling mortality. In this study, seeds of 105 entries of a wide range of sorghum germplasm were screened for seedling resistant to Fusarium moniliforme under laboratory conditions. Inoculum prepared from corn grain internally infestated with a pathological source of F. moniliforme was used to measure the effect of this pathogen on sorghum seedling primary root length, number of secondary branches, and epicotyl length. After seven days in a slant-tray germinator ar alternating temperatures of 20 C for 16 hours and 30 C for 8 hours, seedling from seed treated with the inoculum were compared with the same cultivars in an untreated control and tested 200 ppm benomyl. For 64 cultivars, primary root length, number of secondary branches, and epicotyl length were all reduced by the action of the Fusarium fungus and its toxin an average of 53%, 25%, and 32%, respectively. Few cultivars appeared to be resistant to this pathogen during the early germination stages. The surface sterilizing effect of benomyl and the elimination of internal seed-borne Fusarium were evident throughout this study. Benomyl stimulated primary (...).

Book Description
Specialists from around the world provide a basic diagnostic tool for identifying diseases of the grain and related problems that anyone with a technical background in plant disease diagnosis should be able to use. They cover the many biotic and the few abiotic diseases, beneficial microorganisms, insect pests, and methods of control. Color photographs show clearly the symptoms. The extensive glossary does not indicate pronunciations. The first edition appeared in 1986. Annotation copyrighted by Book News, Inc., Portland, OR

Book Description
Fusarium stalk rot and charcoal rot caused by Fusarium thapsinum and Macrophomina phaseolina respectively are devastating global diseases in sorghum that lead to severe quality and yield loss each year. In this study, three sets of interrelated experiments were conducted that will potentially lead to the development of resistance based control option to these diseases. The first experiment was aimed at identifying sources of resistance to infection by M. phaseolina and F. thapsinum in a diverse panel of 300 sorghum genotypes. The genotypes were evaluated in three environments following artificial inoculation. Out of a total of 300 genotypes evaluated, 95 genotypes were found to have resistance to M. phaseolina and 77 to F. thapsinum of which 53 genotypes were resistant to both pathogens. In the second experiment, a set of 79,132 single nucleotide polymorphisms (SNPs) markers were used in an association study to identify genomic regions underlying stalk rot resistance using a multi-locus mixed model association mapping approach. We identified 14 loci associated with stalk rot and a set of candidate genes that appear to be involved in connected functions controlling plant defense response to stalk rot resistance. The associated SNPs accounted for 19-30% of phenotypic variation observed within and across environments. An analysis of associated allele frequencies within the major sorghum subpopulations revealed enrichment for resistant alleles in the durra and caudatum subpopulations compared with other subpopulations. The findings suggest a complicated molecular mechanism of resistance to stalk rots. The objective of the third experiment was to determine the functional relationship between stay-green trait, leaf dhurrin and soluble sugar levels and resistance to stalk rot diseases. Fourteen genotypic groups derived from a Tx642 × Tx7000 RIL population carrying combinations of stay-green quantitative trait loci were evaluated under three environments in four replications. The stg QTL had variable effects on stalk rot disease. Genotypes carrying stg1, stg3, stg1,3 and stg1,2,3,4 expressed good levels of resistance to M. phaseolina but the combination of stg1 and stg3 was required to express the same level of resistance to F. thapsinum. Other stg QTL blocks such as stg2 and stg4 did not have any impact on stalk rot resistance caused by both pathogens. There were no significant correlations between leaf dhurrin, soluble sugar concentration, and resistance to any of the pathogens.
