Seed Health and Quality Test of Three Rice Varieties for the Detection of Fungi Associated with Seed Sample

University (BAU), Mymensingh during the period of August, 2008 to October, 2009 to detect the fungi associate with the seed samples and to record the germination of seed samples of Parshuram upazila of Feni district. Three rice varieties are collected for the studies were BR6, Pajam and Joya (Local) from Parshuram upazila of Feni district to determine the seed health and quality. For determining the seed health and quality, Dry inspection and blotter tests were performed. Apparently healthy seeds (61.50-78.00%), spotted seeds (6.15-12.90%), discoloured seeds (4.80-14.25%), deformed seeds (2.00-7.25%), varietal mixtures (2.20-9.80%) and chaffy grains (0.95-6.50%) were found among the three rice varieties. The germination of rice seeds of the variety BR6 was 54.67%, while the varieties joya and Pajam showed 58.00 % germination respectively. Nine seed-borne fungi were detected from these seed samples. The identified fungi were Fusarium oxysporum, F. moniliforme, Bipolaris oryzae, Alternaria padwickii, Curvularia lunata, Aspergillus flavus, Aspergillus niger, Penicillium sp. and Nigrospora oryzae. Seeds of rice variety Joya and Pajam carried the lower infection of all the seed-borne fungi than the variety BR6
