英文缩写 PBR
英文全称 Plant breeders' rights
中文解释 植物培育者权利
缩写简介 PBRs are justified on the basis that they encourage investment in plant breeding，the argument being that without legal protection there would be little incentive to develop new conventionally-bred varieties of plants，especially of crops such as wheat and rice that usually self-pollinate，and therefore retain the same genetic make-up through several generations.
