The synthetic Brassica napus L. line No7076 was obtained from a cross between yellow-flowered and zero-erucic turnip rape (B. campestris) Sv85-38301 and white-flowered and high-erucic (41.4%) B. oleracea ssp. alboglabra No6510. This synthetic B. napus is pale-flowered and has an average erucic acid content of 25.8 %. It was crossed with the yellow-flowered and zero-erucic B. napus line SvS4-2S053 and segregation of the erucic acid content and flower colour was studied in F1 and F2 generations. The high erucic acid content was controlled by a single gene in the C-genome and was additively inherited. Strong evidence was obtained in support of independent segregation of the erucic-arid content and the flower colour characters controlled by the C-genome of B. napus. |
