水稻育种目标必须适应水稻生产发展的形势和人民生活水平的不断提高对稻米品质的要求。70年代初,中籼稻育种主要是围绕高产稳产、熟期适中、适应性强的目标进行的。进入80年代以来,随着杂交水稻的迅速推广,中籼稻逐渐处于与杂交稻搭配种植的位置,对中籼稻品种的选育也提出了更高的要求,育种目标则以高产、多抗、优质为主攻方向,熟期上要求与杂交稻错开季节。盐稻2号就是基本符合上述目标的“丰、抗、优”兼备的中熟中籼稻品种。
The goal of rice breeding must be adapted to the situation of rice production and development and the continuous improvement of people’s living standards on the quality of rice. Early 70s, Indica rice breeding is mainly around the high and stable yield, moderate maturity, adaptability of the target. Since the 1980s, with the rapid popularization of hybrid rice, middle-aged indica rice is gradually in the position of hybrid rice with planting, and also put forward higher requirements on the breeding of mid-indica rice varieties. The breeding target is high yield, multi-resistance, As the main direction, the maturity requirements and hybrid rice staggered season. Salt 2 is basically in line with the above objectives of “abundance, resistance, excellent” both medium-maturing indica varieties.
