| Pathumthani 1 is an aromatic non-glutinous and photoperiod insensitive rice. Its yield potential is up to 800-900 kg/rai under suitable fertilizer usage and cultural practices. Average yield on farm trail was damaged by flooding, brown planthopper and bacterial blight about 20 to 50 percent. Improvement of Pathumthani 1 for submergence tolerance, bacterial blight and brown planthopper resistance using molecular marker is one approach to solve this problem. This project was carried out under the commitment between the Rice Department and the Gene Discovery Unit of Kasetsart University. The experiments were divided into two parts, first part was crossing Pathumthani 1 and Pinkaset 1 to introduce bacterial blight resistance gene including Xa21, xa5 and... |
