Chinese researchers breed new rubber tree varieties in Hainan

This photo taken on June 20, 2024 shows seeds of different varieties of rubber trees at a compound under the Chinese Academy of Tropical Agricultural Sciences in Danzhou, south China's Hainan Province. Thanks to efforts by three generations of Chinese researchers, the rubber tree breeding cycle in the country has been shortened from 41 years to 27 years, and eight high-yielding rubber tree varieties that are cold-resistant and wind-resistant have been bred.
