The study was under taken to make an acquisition of knowledge on the relationship of initial seed borne infection of Colletotrichum corchori and jute seed yield parameters under Greenhouse condition. Experiment was conducted at Plant Pathology Department and Greenhouse of Bangladesh Jute Research Institute (BJRI) during July 2011 to April 2012. All together 600 (six hundred) jute seed samples were collected from different sources and categorized as 0.0 %, 5%. 10%, 15%, 20% and 25% initial of pure seed borne infection with C. corchori for further study. Germination of the seed varied significantly and decreased with the increase initial seed borne infection of C. corchori. Germination failure/dead seed, infected seedlings and total dead seed varied significantly and increased with the increase of initial seed borne infection of C. corchori. There were negative relationships between, seed yield parameters of the harvested seeds of CVL-1 produced in Greenhouse with initial seed borne infection of C. corchori. The regression coefficients for germination, plants/pot, seeds/pod and seeds/plant were -1.048, -0.403, -0.756 and -34.24, respectively. On other hand, relationship of infected seedlings and total dead seeds in Greenhouse were positive with the initial seed borne infections of C. corchori and the regression coefficients for infected seedlings and total dead seed were 0.248 and 0.751, respectively. Since, anthracnose of jute caused by fungus Colletotrichum corchori is a seed borne disease and transmit from seed to plant to seed and consequently hamper the quality and yield of fibre and affect the seed quality and seed yield as well and thus necessary precautions should be taken before sowing and after germination of the seeds to produce higher yield and quality jute seed and fibre.
