摘要
本文主要是对近十年,本所的甘蔗新品种选育和广东省的甘蔗良种推广工作作一个评述,对良种工作的变化发展,所取得的成就予以肯定,对存在问题提出一些看法、意见及建议。新品种的不断育成,“新一代”CP 品种作亲本的有效利用,随着粤糖63—237等良种的迅速推广,“台糖134时代”已基本宣告结束。但是,海南甘蔗育种场连续几年亲本开花不正常,可用的优良亲本不多,且亲缘关系狭窄,新育成品种繁殖推广缓慢,这些都是当前我们甘蔗良种工作上较突出的问题。
This paper deals primarily with the work of breeding new varieties in our institute and spreading improved varieties in Guang Dong province in the recent ten years.The changes and developments are reviewed in the breeding,and its achievements are affirmed.The opinions and suggestions about the existing problems are put forward. With the interrupted development of new varieties,the effective use of the CP varieties as parents and the rapid extension of improved varieties such as Yuetang 63/237,“The Taitang 134 Age”,at which Taitang 134 was a predominant variety,has been over on the whole.But,there are the following obvious problems existing currently in our sugarcane breeding: sugarcane as parents has not flowered normally for years on end at Hainan Sugarcane Breeding Station;there are few available excellent parents;the blood relationship between crossing parents is close;the speed of spreading new developed varieties is slow.
