Genetic Diversity of Bacterial Leaf Blight Disease in a Set of Rice Landraces of West Bengal
Bacterial Leaf Blight (BLB) is a major disease of rice in tropical monsoon and sub tropical rice growing regions of the world. BLB substantially reduces the yield of the crop affecting food security. Rice is the second most important food crop, after wheat, in the world; hence the disease must be effectively controlled. As chemical control is impractical due to unavailability of specific bacter...
متن کاملDisease Severity and Yield of Sweet Corn Hybrids with Resistance to Northern Leaf Blight
Northern leaf blight (NLB), caused by Exserohilum turcicum (Pass.) K. J. Leonard & E. G. Suggs), is a prevalent disease of sweet corn (Zea mays L.) in the United States. Fungicides are used routinely to prevent severe epidemics of NLB on nearly 20,000 ha of supersweet (sh2) hybrids grown each spring in southern and central Florida. Epidemics of NLB on sweet corn grown in the midwestern United S...

متن کاملDetection of bacterial blight resistance genes in basmati rice landraces.
Aromatic basmati rice is vulnerable to bacterial blight disease. Genes conferring resistance to bacterial blight have been identified in coarse rice; however, their incorporation into basmati varieties compromises the prized basmati aroma. We identified bacterial blight resistance genes Xa4, xa5, Xa7, and xa13 in 52 basmati landraces and five basmati cultivars using PCR markers. The Xa7 g...
متن کاملThe role of silicon in enhancing resistance to bacterial blight of hydroponic- and soil-cultured rice
Here we report for the first time that bacterial blight of rice can be alleviated by silicon (Si) added. In both inoculated and uninoculated plants, shoot dry weight was significantly higher in the +Si plants than in the -Si plants. A soil-cultured trial showed that disease severity was 24.3% lower in the Si-amended plants than in the non-Si-amended plants. Plants that were switched from -Si to...
