目前推广的杂交水稻组合多属迟熟中稻类型。为了适应我区地形条件复杂、栽培制度多样的特点,实行早、中、迟熟配套,我所从1976年开始进行了早中熟杂交稻新组合的选育工作。现将初步育成的早中熟杂交水稻“珍汕97A×28选”(简称“汕八选”)几年来的选育工作初报如下。 At present, the hybrid rice combination promoted mostly belongs to late-maturing mid-rice type. In order to adapt to the complex terrain conditions in our area and the diversified cultivation system, we implemented the early, medium and late maturing facilities. Since 1976, we have carried out the breeding of a new hybrid rice combination of early-middle maturity. The preliminary bred early hybrid rice “Zhenshan 97A × 28 election” (referred to as “Shan eight election”) breeding work in the first few years as follows.
