华中农业大学蔡得田等研究出一种“卵不受精”,自发结果的“奇稻”。“奇稻”是一种新的无融合生殖水稻材料。该研究成果居世界领先地位,是水稻育种史上的又一里程碑。杂交水稻丰产性好,但制种技术复杂,生长周期长,受气候影响大。与之相比,无融合生殖水稻材料固定杂种优势后,就可省去了制种过程,和常规品种一样,代代相传。这种繁殖方式兼有无性和有性繁殖的长处,用它培育新品种,时间
Huazhong Agricultural University, such as Cai Detian developed a “egg is not fertile,” spontaneous results of “odd rice.” Odd Rice is a new apomictic rice material. The research results in the world leader in rice breeding history is another milestone. High yield hybrid rice is good, but the seed production technology is complex, long growth cycle, affected by the climate. In contrast, the apomixis of immortalized rice material eliminates the need for seed production, as it is for conventional varieties, and is passed on from generation to generation. This breeding method combines the advantages of vegetative and sexual reproduction, use it to cultivate new varieties, time
