Variety introduction

In the selection of navel orange varieties, Xinfengyu 197 1 introduced Washington navel orange from Shaoyang, Hunan, with excellent performance. 1979, Huazhong agricultural university introduced a new strain of navel orange 12 from the United States and Spain, 198 1 year, and Professor Zhang Wencai selected 8 of them to plant in Gannan.

After more than ten years of experiment, domestication and comparison in southern Jiangxi, some excellent varieties such as Newhall, Penna and Nevina suitable for planting in warm and humid climate in southern China were screened out.

Later, in the specific production practice, Newhall was favored by the majority of fruit farmers and became the main variety because it was superior to Penner and Nevilina in fruit shape, color and flavor. The area of Newhall navel orange accounts for 88% of the total area of navel orange, while Bona and Nevina only account for 8% and 3% respectively.
