七十年代末期在江西南部的崇义县原始森林中发现的野生桔,其形态特征与已见诸报道的柑桔属中野生种质有明显的差异性。因其产地处于南岭山脉支系的特定环境中,立地条件优越,并有多种近缘植物,应是在长期自然演化和发展过程中形成的原生物种。因此,可以说明南岭山脉地区是我国宽皮类种质起源地。 In the late seventies, wild oranges found in Chongyi County’s primeval forest in southern Jiangxi Province were significantly different in morphological characteristics from the reported wild citrus germplasms. Because of its origin in the Nanling Mountains Branch of the specific environment, site conditions are superior, and a variety of related plants, should be formed in the long-term natural evolution and development of native species. Therefore, it can be explained that the area of ​​Nanling Mountains is the origin of China’s broad-leaved germplasm.
