一、前言我省野生稻资源丰富多采,既有普通野生稻(Oryza sativa L.f.spontanea)、药用野生稻(O.officinalis Wall),又有疣粒野生稻(O.meyeriana Baill)等。关于普通野生稻方面,Merrill(1917)曾在博罗县罗浮山麓的长宁、福田至石龙一带发现;丁颖(1926)在广州市郊犀牛尾的沼泽地也有发现;随后,北从英德,南至海南岛,由粤东的普宁至粤西雷州半岛、鉴江流域的广大地区,均有发现。丁颖(1933)曾利用广州野生稻的种质导入栽培稻品种,育成了适应性广,抗病虫性、抗逆性较强的“中山1号”。嗣后,通过不断的系统选择,选出“包选2号”、“广二选二”等衍生
I. INTRODUCTION The wild rice in our province is rich in resources, including Oryza sativa L.f.spontanea, O. officinalis Wall and O. meyeriana Baill. On common wild rice, Merrill (1917) was found in the Changning, Futian-Shilong area of Luofu Mountain in Boluo County; Ding Ying (1926) was also found in the marsh of the rhinoceros tail in the suburbs of Guangzhou; South to Hainan Island, from Puning in eastern Guangdong to Leizhou Peninsula in Guangdong Province, Kam River basin in vast areas, have been found. Ding Ying (1933) used the germplasm of Guangzhou wild rice to introduce cultivated rice varieties and developed “Zhongshan No.1” with wide adaptability, pest resistance and strong resistance. Subsequently, through continuous system selection, elected “package election No. 2”, “Kwong II election two” and other derivatives
