1988年,水稻84-15的无融合生殖在北京通过遗传鉴定,初步认定84-15是一个兼性无融合生殖选系。它的特点是不需要年年制种,可以多代利用。因此省种、省工、省时、减少投入,杂种优势明显。产量水平优于常规梗稻或相当于杂交粳稻,便于广泛利用。它的研制成功,是三系杂交水稻和常规水稻育种的新发展。无融合生殖水稻选育的基本原理是用亲和基因
In 1988, the apomictic reproduction of rice 84-15 passed genetic identification in Beijing. It was initially concluded that 84-15 was a facultative apomictic germline. It is characterized by not need year-long seed, can be used for many generations. Therefore provincial species, labor-saving, time-saving, reduce input, obvious heterosis. Yield level is superior to conventional stem rice or equivalent to hybrid japonica rice, easy to widely use. Its successful development is the new development of three-line hybrid rice and conventional rice breeding. The basic principle of apomictic rice breeding is the use of affinity genes
