“Jijing 88”,a variety of brown rice was treated with laser at different wavelength and power to induce variation.The results showed that the more treated times and the stronger of power,the less of seedling obtained.Many characters of the variety appeared genetic variation.Among quality characters the awn changed the most,which account for 80% of total plants.Then is grain density,grain length,maturing time and plant height.Among quantitative characters the tiller rate changed the most.Then is grain per panicle and grain weight.The experiment demonstrated that laser treatment at the power of 10-20 mw and 5-10 min could get ideal effect.So the laser treatment could be a new method in rice breeding.
