一、常规稻的贡献 1926年由著名农学家丁颖教授在广东省主持设立中山大学稻作试验场开始,用农家品种“竹占”与广州野生稻的自然杂交材料,于1931年育成耐寒和抗逆性较强的晚籼品种中山1号,曾在广东省西南部地区推广。其后同样用常规育种法选育出早籼暹黑7号和晚籼成雪9号等品种,在华南地区一度推广。新中国成立后,广东省水稻常规育种逐步发展,不断育成新品种,贡献很大。五十年代初期,华南农科所(广东省农科院前身)用胜利籼与南特号杂交育成中熟籼稻品种广场13,1954年开始推广,当时表现稳定高产,曾达到500万亩的推广面积。
First, the contribution of conventional rice In 1926 by the famous agronomist professor Ding Ying presided over the establishment of Zhongshan University in Guangdong Province rice test site began with the farm variety “bamboo accounted ” and Guangzhou wild rice natural hybrid materials, bred in 1931, hardy And the late indica variety Zhongshan No.1 with strong resistance had been popularized in the southwestern part of Guangdong Province. Subsequent breeding by conventional breeding methods like early Indica Siamese 7 and late indica Chengxue 9 and other varieties were once promoted in southern China. After the founding of new China, Guangdong Province, the gradual development of conventional rice breeding, breeding new varieties continue to make great contribution. In the early 1950s, South China Institute of Agronomy (the predecessor of Guangdong Academy of Agricultural Sciences) was successfully popularized by the hybrid rice of Victory Indica and Nante No. 13, which was started in 1954. At that time, it showed steady and high yield and had reached 5 million mu area.
