海南甘蔗育种场是我国甘蔗杂交基地,担负着向全国各育种单位提供杂交种子的任务。然而,除大多数甘蔗品种开花外,还有热带种(如黑车里本、斐济、卡里斯泰林那、黄加俐、条纹车里本等)和热带血缘重的材料(爪哇3016、粤糖57/423等)难以开花及主要杂交亲本台糖134抽穗率低,因而在一定程度上影响到杂交任务的完成。为 Hainan sugarcane breeding farm is the base of sugarcane hybridization in China, which is tasked with providing hybrid seeds to various breeding units throughout the country. However, in addition to the flowering of most sugar cane varieties, there are tropical species (such as black carriages, Fiji, Caristella, yellow, stripe carriages, etc.) and tropical kin materials (Java 3016, 423, etc.) difficult to flowering and the main hybrid parent Taiwan sugar 134 low heading rate, which to some extent, affect the completion of hybridization tasks. for
