[QTL for seed germination rate and related physiological traits of Brassica napus L].

One hundred and eighty-three recombinant inbred lines from the cross between GH06 and P174 were used for genetic analysis of seed germination rate and physiological trait analysis of Brassica napus L. Composite interval mapping (CIM) was applied to identify QTL associated with seed germination rate (GR) of the seeds that stored for two years (STY), one year (SOY), and fresh seeds (FS), respectively. The activity of lipases, seed conductivity, reducing sugar content, total sugar content, and root vitality of STY and FS were investigated.

Localization of QTLs for seed color using recombinant inbred lines of Brassica napus in different environments.

Yellow seed is one of the most important traits of Brassica napus L. Efficient selection of the yellow-seed trait is one of the most important objectives in oilseed rape breeding. Two recombinant inbred line (RIL) populations (RIL-1 and RIL-2) were analyzed for 2 years at 2 locations.

[SRAP study on genetic diversity of radix plygoni multiflori in chongqing].

Objective: To detect the polymorphisms of Radix Plygoni Multiflori in chongqing by means of a new marker system SRAP.

Method: Different shaples of Radix Plygoni Multiflori from major production areas were collected. The SRAP was used to asses divergence among 16 populations.
