AV RDC的大豆种质资源研究
- Title:
- SOYBEAN GERMPLASM RESEARCH AT AVRDC
- Keywords:
- Soy bean; Germpla sm; AV RDC
- 文献标志码:
- A
- 摘要:
- 根据AV RDC历年研究年报内容,本文简要介绍了其大豆种质资源研究进展。从1973年到1995年底AV RDC共收集大豆种质资源13, 618份,目前已全部保存在中期库和长期库中。1986年建立了一套完整的中心化种质引进系统,新引进种质主要信息供所有科学家利用。针对热带地区大豆种子储存难的问题,对大豆种质储藏条件、种子寿命,储藏期间的生化物质变化及保存技术进行了较多的研究。大豆育种家、病理学家、昆虫学家及种子研究室的研究人员对AV RDC收集的大部分种质,对高产、早熟、光周期不敏感、抗病、虫等性状进行了评价,筛选出一些供育种利用的有益的基因源。利用筛选出的优异种质, AV RDC的科学家配制了大量不同育种目标的杂交组合,培育出了一大批结合高产、抗病、早熟、光温不敏感,适合热带、亚热带地区种植的高代选系。AV RDC还免费向国家育种机构或个人发放其收集的种质、育成的低代或高代选系,大量种质的扩散促进了其在亚热带、热带地区的利用。

- Acco rding to AV RDC a nnual Prog ress Repor ts, We review ed the adv ances ofsoybean g ermplasm researches a t AV RDC. AV RDC had int roduced 13, 618 so ybeang ermpla sm accessio ns f rom more than 50 count ries or areas during 1973- 1995. All thesoybean accessio ns are co nserv ed in lo ng- term a nd medium- term sto rag e rooms. Anew cent rali zed g ermplasm introductio n sy stem was setabli shed in 1986 and has beenused since that time. All the col lectio ns have their ow n passpo rt data w hich are availableto all scientist s. In order to understand the nature o f di fficulty fo r sto rag e of so ybean seeds, mo re researches w ere co nducted o n storage tech niques, storag e co ndi tio ns, seedlo ng evi ty , cha ng es o f seed chemical substa nces in the period o f sto rag e.
