基本情况我区开展水稻辐射育种工作已有十多年了,近年来又有较大的发展。选育出一批优良品系和辐射后代材料,其中一些新品种已在生产上扩大试验,逐步推广。同时还积累了一些辐射育种的技术经验,为进一步开展水稻辐射育种的科学实验打下了良好基础。辐射育种就是利用电离辐射诱导植物产 Basic situation I conducted rice radiation breeding work in our area for more than 10 years, and in recent years have a greater development. Bred a number of fine lines and radiation offspring materials, some of which new varieties have been expanded in the production test, and gradually promote. At the same time, some technical experiences in radiation breeding have also been accumulated, laying a good foundation for further conducting scientific experiments on radiation breeding in rice. Radiation breeding is the use of ionizing radiation to induce plant production
