广西栽培稻资源类型初析

PRELIMINARY STUDY ON THE TYPES OF GUANGXI GERMPLASM RESOURCES OF ORYZA SATIVA L

广西稻种资源数量多,类型丰富,在国内外占有重要地位;广西是研究亚洲栽培稻(O.sativa,L.)分类、起源、演化的重要地带之一.过去国内外对广西稻种资源研究和了解甚少.本文根据多年调查、归类、观察、研究的结果和体会,从传统分类的角度,概述广西稻种的基本类型和特殊类型,及其形态特点、地理生态分布、栽培特点、利用前景等,试图展示其概貌,并对深水稻、粳糯稻等类型的分类问题提出一些疑问和见解,以供研究和利用参考.

Guangxi Possesses a vast range of rice germplasm reources which covets an abundant types. It is one of the important regions to study the taxonomy, origination and evolution of Oryza sativa L. in China.Right now, work to study the topic is very little both in China and the rest of the world. This paper outlines the basic & specific types of Guangxi rice germplasm resources,morphological appe-arnces,geographic & ecologic distrbutions,culture piactices and utilization perspectives etc.It also indicated the general picture of Guangxi rice germplasm resources. Herein several questions and views have been Proposed refer to the cassificatiou of deep water varieties & the keng and glutinous rice for further study.
