转基因技术在黄瓜性状改良中的应用及战略思考

Application and Strategic Thought about Transgenic Technique in C ucumber Improvement

20世纪90年代,开始应用基因工程技术培育黄瓜新品种,在一定程度上打破了生物间的生殖隔离,使黄瓜育种更具有目的性和针对性,同时还解决了黄瓜传统育种过程中周期较长、种质资源狭窄及有益性状资源匮乏等难题。本文综述了黄瓜转基因研究所取得的进展,如改善了黄瓜的抗病性、抗虫害、抗逆性、品质、抗除草剂、单性结实和产量等;讨论了转基因黄瓜巨大的商业化潜力;指出近期黄瓜转基因的目标,以及在今后黄瓜转基因工作过程中应注意评估转基因黄瓜的生物安全和商业化过程中存在的其他问题,并对转基因黄瓜的食品和生物安全战略进行了探讨。

Since the 20th century 90's,genetic engineering technology has been used to cultivate new cucumber(Cucumis sativus L.)variety.To certain extent this has broken the reproductive isolation between bioses and made cucumber breeding with clearer objectives.At the same time,it has also solved problems existing in traditional cucumber breeding,such as longer cycle,narrow germplasm resources and lack of germplasm resources with useful characteristics.This review summarized the progress made in transgenic cucumber,such as disease-tolerance,insect-tolerance,stress-tolerance,quality,herbicide tolerance,parthenocarpic fruits and yield,etc.It also discussed about the huge commercial potential in cucumber,pointed out the aims of transgenic cucumber in recent years.This review also focused on other issues like biology safety and commercialization of transgenic cucumber.It carries out discussion on transgenic cucumber food and bio-safety strategy.
