芥菜型油菜种质资源研究进展

本文从收集保存、鉴定、研究、创新和利用5个方面介绍了芥菜型油菜种质资源研究进展。芥菜型油菜起源于亚洲,印度、中国收集的资源最多。芥菜型油菜可以分为中国-东欧类型和中国-印度类型2大类,每一类中均存在较大的遗传变异,许多具有优良性状的种质已经鉴定出来,并对其进行了生理学、遗传学研究。通过远缘杂交、诱变和遗传转化已创造出芥菜型油菜新种质。已鉴定、培育的芥菜型油菜优异种质资源在油菜育种上得到广泛利用。

Advances in Germplasm of Oilseed Brassica juncea

The advances in germplasm of oilseed Brassica juncea were presented with respect to collection and conversation,evaluation,physiological and genetic characterization,enhancement and utilization.Oilseed Brassica juncea originates from Asia.India and China have the greatest collection of the species.Oilseed Brassica juncea could be divided into 2 major groups: China/East European and China/Indian.There is a great genetic variability in each group from which a number of accessions with the desired traits have been identified,and physiologically and genetically characterized.Many oilseed B.juncea accessions with novel traits have been developed through distant hybridization,induced mutation or genetic transformation.The desired oilseed B.juncea accessions have been extensively exploited in Rapeseed breeding.
