 ABSTRACT

The study was carried out at the Laboratory, Department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh, Bangladesh during the period from March, 2004 to October 2004 to screening of tolerant jute cultivars (Corchorus capsularis) against jute yellow mosaic disease. Four jute cultivars CVL-1, CC-45, D-154 and BJC-7370 were used for this study. The tested cultivars were assigned to plots randomly having six replications and exposed to natural infection of leaf yellow mosaic virus. Data on percent incidence, growth and yield components of the infected as well as healthy plants were collected, compared and interpreted. The test cultivars differed significantly in terms of incidence and severity of disease. The cultivars CVL-1 and BJC-7370 showed best performance against leaf mosaic disease, other two varieties were comparatively more affected by leaf mosaic. Leaf mosaic disease reduced the growth and yield contributing components of jute. Among the four test cultivars CVL-1 performed the best when none of the test Cultivars was free from leaf mosaic disease infection.
