The strain 5862R,with yellow seed and double low and high content of oil was selected from 6003 (black seed and double low) crossed with 408(yellow seed and double low) through 8 generations. Its yellow seed frequency was 91.6%-96.2%.The contents of erucic acid and glucosinolate were 0.08%-0.14% and 24.6-39.14 μmol/g,respectively and oil content was 46.7%-49.3%,the yield level was near Zhongshuang No.4. The strain had been used by restoring line,bred a combination of hybrid rape for Youyan No.9.It has been tested and a proved to pass through Guizhou province in 1998.Its total spreading area has been reached 40000ha in Autumn 2001.
