英明领袖华主席在第二次全国农业学大寨会议期间指出:“一定要研究出早熟高产的品种来。”最近在视察东北三省时又指示:“粮食品种要选育早熟高产的,光早熟不高产也不行。”华主席的指示,不仅为东北也为全国选育新品种指明了方向,我们要坚决贯彻执行。要树雄心,立壮志,为发展我国农业生产作出新贡献。从我省农业生产发展上急需解决早熟高产的作物新品种的实际出发,我们于1974年开始,采用辐射育种与杂交育种相结合的方法。即用快中子照射早籼“大粒溪丰”作父本,与早熟品种“红梅早”杂交,从子二代起,根据选种的目标,对株型,穗型和粒型进行定向选择,仅用二年半的时间就基本定型,并定名为“红丰早”。1976年早造进行小区品比,晚造翻秋繁种,今年早造在本省增城,从化、新丰、南海郁南等县进行试种,试种结果一般表现良好,比当地早熟及中熟当家品种有较明显的增产效果。现将试种情况及该品种的种性摘要总结于后;
During the Second National Conference on Agriculture in Dazhai, wise leader Chairman Hua pointed out: “It is imperative to study varieties with early maturity and high yield.” Recently, when inspected the three northeastern provinces, they also indicated: “The grain variety should breed early and high-yielding and light early-maturity Not high yield is not enough. ”Chairman Hua’s instructions not only pointed out the direction for northeast China but also for breeding new varieties nationwide, and we must resolutely carry it out. To tree ambition, ambition, to make new contributions to the development of China’s agricultural production. From the urgent need to solve the practical problems of early crop and high yield of new crop varieties in the agricultural production development in our province, we started with the method of combining radiation breeding and crossbreeding in 1974. That is, with fast neutron irradiation early Indica “Dazi Xifeng” as the father, and the early maturing variety “Hongmei early” hybrid, from the second generation, according to the target of selection, plant type, panicle type and grain orientation Choice, only two and a half years on the basic stereotypes, and named “Hongfeng early.” As early as 1976, the plot ratio was made as early as in the autumn, and the variety of the autumn was made later. As early as this year, the trial planting was carried out in Zengcheng, Conghua, Xinfeng and Yu Nan Counties of the South China Sea. The results of the trial planting generally performed well and were earlier than the local ones When the family has a more obvious yield increase. At present, the test situation and the species summary of the species summarized in the later;
