Book excerpt: 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 (...).

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Grain mold (GM) is an important biotic constraint limiting yield and market value of sorghum grains. It results in kernel discoloration and deterioration. Such kernels have reduced seed viability, low food and feed quality. Breeding for grain mold resistance is challenging because of the complex nature of host-pathogen-environment interactions. This complex task could be made simpler by utilizing molecular markers. Utilization of marker resources may help to find genomic regions associated with grain mold resistance. In this study, three sets of field and laboratory based experiments were performed which will help in finding potential grain mold pathogens responsible for kernel deterioration in the studied environment and search for genotypes with better kernel quality and grain mold resistance. In the first part of the study, in vitro screening of 44 grain mold resistant sorghum genotypes developed and released by Texas A & M AgriLife Research. This study was aimed at identifying sources resistance to grain mold infection through laboratory screening. The result revealed that genotypes Tx3371, Tx3373, Tx3374, Tx3376, Tx3407, Tx3400, and Tx3402 were have high level of resistance and were identified as potential sources of grain mold resistance as each showed minimal fungal infection and higher grain quality traits. The second experiment was performed to optimize surface sterilization protocol for the extraction of fungal pathogens from the kernel surface (pericarp) and to study the effect of bleach percentage and time period on pathogen extraction. Seven treatments using sterilized double distilled water (0 % bleach (v/v)) and different bleach (NaOCl) concentrations (2.5, 5, 7.5, 10, 12.5 and 15 %) were used with a time interval of 2.5, 5, 7.5 and 10 min. Optimized surface sterilization in the range of 7.5 to 15 % bleach (v/v) for 7.5 to 10 min resulted least contamination and fungal genera isolation from the surface of the kernel. The third study was aimed at characterizing genotypes (sorghum association panel) for grain mold pathogen F. thapsinum and by using genome wide association (GWA) tool in order to find genomic regions associated with grain mold resistance. We studied the effect of different agronomic and panicle architecture traits on grain mold incidence and severity. Effects of grain mold on kernel quality traits were also studied. We reported two loci associated with grain mold resistance. Based on first year field screening results, 46 genotypes having grain mold ratings 1-5 (1 = 1% panicle kernel molded; 5 = 50% panicle kernel molded) were selected for a detailed study aimed at understanding grain mold x fungal pathogen interactions to physical and chemical kernel traits. Seed germination test, vigor index, and tetrazolium viability test were performed to study effect of grain mold infection on kernel viability and vigor. Alternaria, Fusarium thapsinum, F. verticillioides and F. proliferatum were the main fungal genera isolated from bisected kernels. Based on two year screening, SC623, SC67, SC621, SC947 and SC1494 were most resistant based on both PGMR and TGMR rating while SC370, SC833, SC1484, and SC1077 showed the most susceptible reaction and this was consistent for individual location analysis. SC309, SC213, SC833, SC971 and SC1047 are genotypes having identified loci for grain mold resistance.
