Program on research and development of rainfed lowland rice in north eastern Thailand in collaboration with the National Centre for Genetic Engineering and Biotechnology (BIOTEC) have carried out the project to develop an early maturing, blast resistant, non-glutinous rice variety. The cross between IR57514-PMI-5-B-1-2 and RGDU99016-MAS-77 was developed and the progenies were backcrossed to IR57514-PMI-5-B-1-2 for 3 time at RGDU, BIOTEC. The selected promising line; RGDU06337-MAS-24-B-B, was finally obtained. This line is a non-glutinous, photoperiod sensitive, early maturing line which flowers approximately on October 8 and is ready for harvest on November 11. The average number of panicles per hill is 11 panicles. The average plant height is 114 cm. with... |

Considering the importance of blast, caused by Pyricularia oryzae, to reduce wheat yield, this study investigate how silicon (Si) could reduce the wheat blast symptoms in the rachis tissues using light microscopy and scanning electron microscopy. Wheat plants (cv. BR 18) were grown in hydroponic culture with either 0 (–Si) or 2 mM (+Si) of Si. Blast symptoms were very well developed on the spikes of the –Si plants, which showed intense discoloration in contrast with the spikes of the +Si plants. At 72 hours after inoculation (hai), fungal hyphae extensively colonized the epidermis and the collenchyma tissue in the radial direction in the rachis of the –Si plants. In the +Si plants, fungal hyphae colonized the epidermis and the collenchyma cells to a lesser... |
