繁殖制种的产量与质量将直接影响到杂交水稻的发展速度,为了搞好一九七八年繁殖制种工作,我们根据几年来各地的经验,提出以下几点主要技术意见,供参考。一、保证种子纯度杂交水稻种子的纯度,直接关系到杂种优势的发挥,混杂严重的种子,不仅不会增产,而且还会减产。要保证种子的纯度,需要在繁殖制种时进行严格隔离,去杂,防止错乱。
The production and quality of breeding and seed production will directly affect the development speed of hybrid rice. In order to do a good job in breeding and breeding in 1978, we propose the following major technical opinions based on the experience of the past few years for reference. First, to ensure the purity of seeds The purity of hybrid rice seeds is directly related to the play of heterosis, mixed with heavy seeds, not only will not increase production, but also cut. To ensure the purity of the seeds, the need for strict isolation in breeding seed, miscellaneous to prevent confusion.
