The invention discloses a method for breeding a special ornamental rape variety. The method comprises the steps of utilizing a radish cytoplasmic sterile line of
brassica napus as a female parent anda
brassica juncea strain as a male parent, and carrying out hybridization to obtain filial generation, namely a special ornamental rape variety. The radish cytoplasmic sterile line of the
brassica napus is utilized as a platform, and the special ornamental rape variety suitable for being planted in a scenic area is created through an
interspecific hybridization method, so that the method is simpleto operate, short in breeding period, high in
hybrid seed yield, high in purity and good in quality, and can ensure the consistency of the variety in production performance; the bred
hybrid can maintain a tall rape
plant, vigorous growth of a vegetative body, large and flat petals, lateral overlapping growth, multiple branches, a long flowering period and
purplish red leaves in a
seedling stage;and the special ornamental rape variety can be used for viewing, and is very suitable for the viewing requirements of the scenic area. The method is high in universality, can be generalized to breeding of other similar varieties, provides a reference method for cultivating more and better landscape or a rape variety required for
agriculture and tourism combination in practice and has great significance.
