牡丹江地区地处我国东北边疆,气候寒冷,年平均气温只有2—4℃,无霜期短,只有100—135天,水稻常因遭受早霜危害而减产。稻瘟病也常发生。所以,这里对栽培的水稻品种的要求比较严格。过去,由于修正主义科研路线的影响,在育种工作中忽视熟期和抗病性,不顾当地特点片面追求高产,结果确定推广的品种多,而真正站得住脚的品种少。我区农业要大上快上,就急需培育早熟、抗灾、高产、质佳、适应性强的新品种,单靠常规育种方法在较短时间内是难以达到目标的。因此,必须实行革命性的突破,加快育种速度,缩短育种周期。1971年我们从资料上看到有关单倍体育种技术的报道,很受启发,于是便开始了水稻单倍体育种的研究。 Mudanjiang is located in northeastern China’s border, climate is cold, the annual average temperature is only 2-4 ℃, frost-free period is short, only 100-135 days, often due to early frost damage to rice production. Rice blast often occurs. Therefore, the cultivation of rice varieties here is more stringent requirements. In the past, due to the influence of the revisionist scientific research route, the neglect of maturity and disease resistance in breeding work and the one-sided pursuit of high yield regardless of local characteristics have led to the identification of more varieties to be popularized and the fact that there are fewer varieties that really stand out. In agriculture in our region, we should urgently need to cultivate new varieties that are precocious, disaster-resistant, high-yielding, good quality and adaptable. It is difficult to achieve the goal in a relatively short period of time by conventional breeding methods alone. Therefore, we must implement a revolutionary breakthrough to speed up breeding and shorten the breeding cycle. In 1971 we learned from the information on haploid breeding technology, very inspired, so they began the study of rice haploid breeding.
