近几年来,国内新育成一批晚粳稻品种,并引进了一些“国际稻”系统品种。为了提供引种、栽培和处理杂交亲本的某些依据,我们对这些品种有关光温反应特性进行了初步研究。 试验的材料和方法 晚粳稻选用当前在长江中下游大量栽培或正在进行区域试验的沪选19号、冈稻02、鄂晚3号、农虎6号、公社16号、嘉农15号、苏粳4号和农垦58(对照)八个品种;国际稻选用国际8号(IR8号即691)和国际26号(IR26号)两个品种。
In recent years, a new batch of late japonica rice varieties have been bred in China and some “international rice” system varieties have been introduced. In order to provide some basis for the introduction, cultivation and processing of hybrid parents, we conducted a preliminary study on the light and temperature response characteristics of these varieties. Materials and Methods of Experiment Late japonica rice was selected from the sites of Hu Xuan No. 19, Gangdao 02, Hubei No.3, Nonghu No.6, Commune No.16, Jianong No.15, Su-19 at the current large-scale cultivation or ongoing regional trials in the middle and lower reaches of the Yangtze River. Japonica 4 and Nongken 58 (control), and the international rice was selected from two varieties of International No. 8 (IR8 No. 691) and International No. 26 (No. IR26).
