The characteristics of high- and low-erucic acid rapeseed (Brassica napus L.).

Name	Seed oil content (%)	Erucic acid content (%)	Weight /1,000 seed (g)	Diameter (mm)
WH3401	54.52 ± 2.00	34.05 ± 0.26	3.31 ± 0.10	1.84 ± 0.04
WY20	42.60 ± 0.97**	0.20 ± 0.25**	4.00 ± 0.07**	1.99 ± 0.06**

Two inbreed accessions were naturalized in Hubei for many years, the agronomic traits trend to be stable. The data of seed oil content, erucic acid content and seed weight are the average value of 3 years. Open-pollen seeds were analyzed by near infrared spectrometer and 5 plants were analyzed for each accession every year. ** denotes significant difference at P < 0.01 using student t-test.
