摘　　要：着重介绍了无籽西瓜发展历程、目前无籽西瓜的原理、西瓜四倍体除草剂Oryzalin诱变的科研进展、Oryzalin诱变四倍体西瓜的前景以及分析了无籽西瓜科研与生产中存在的问题。在无籽西瓜生产和科研实践中,往往是重栽培,轻品种改良。Oryzalin是一种强有效的染色体加倍诱变剂,它通过与受体微管蛋白亲和,干扰植物细胞的正常有丝分裂,使细胞染色体加倍,且具有超越秋水仙碱的诸多优点。Oryzalin加倍技术的出现和应用,使工厂化、大通量、系统化研究和培育四倍体、三倍体西瓜育种成为现实,必将带来育种技术和品种的新突破,显示广阔的应用前景。This paper mainly introduced the development and current principle of seedless watermelon, the research progress and the prospects of herbicide Oryzalin in tetraploid watermelon mutation, the problems of seedless watermelon existed in scientific research and production. The production and scientific research of seedless watermelon were emphasized cultivation, lose sight of breeding improvement usually. Oryzalin was a potent beyond the colchicine chromosome doubling mutagen in many advantages, through plant tubulin affinity, preventing mitosis in plants, and achieving the effect of chromosome doubling. Oryzalin doubling techniques and applications, it became a reality of the factorization, high flux, systematic research and cultivate tetrapioid, triploid watermelon. It will bring new breakthrough in breeding technology and varieties and display a wide range of applications.
