Study and Evaluation on Rapeseed Germplasm Resources in Shaanxi

The collection,collate,identification and evaluation of rapeseed germplasm resources of Shaanxi Province have made clear the following points:1.Ecological types and their distribution of rapeseed germplasm resources in Shaanxi Province.2.Morphological characteristics and yield components of rapeseed germplasms resources in Shaanxi Province.The plateau of the north of Shaanxi is a ecological region which can produce high oil content rapeseed and B.juncea in this region has not only high oil content but also special fatty acid components.In addition,11 germplasms with high tolerance to virosis were screended out.We have made clear the restoring and maintaining relationships of germplasm resources to male sterile line in hybrid rapeseed breeding in B.napus and also evaluated the exotic rapeseed germplasms.
