为了在北京地区水资源严重不足的条件下,稳定和发展稻米生产,我们在1982年提出了水陆稻杂交种选育的设想,即利用杂种一代可能直接综合双亲性状的特点,企图把水稻的丰产性和陆稻的抗旱性,以及它们的其它优点,在杂种优势的利用中结合起来,选育水旱兼用优势较强的杂交组合,这样就可能把节水种稻提高到一个新的水平。根据 In order to stabilize and develop rice production in Beijing under severe water shortage conditions, we put forward the idea of ​​breeding hybrid inland and paddy rice in 1982. By using the characteristics that the hybrid generation may directly integrate the parents’ traits, it is attempted to combine the high yield of rice Sexual and upland rice drought resistance, as well as their other advantages, combined with the utilization of heterosis, the combination of water and drought with the advantages of strong hybrids, so that water-saving rice may be raised to a new level. according to
