Embodiment 1

[0017] A breeding method for white-flowered rape, the method comprising the following steps: selecting the main cultivar of Brassica napus with superior plant growth, lodging resistance, and strong disease resistance to hybridize with radish with white petals to obtain F0 seeds; after sowing the F0 seeds, select The main inflorescence of an excellent single plant is reserved to obtain F1 seeds, and then the F1 seeds are mixed and sowed. From F2, plants with the target flower color are selected for self-bagging and bagged for seeding, and single plants of crude oil rapeseed varieties are eliminated. After years of continuous self-fertilization Separation, until F6 begins to appear in individual plots with the same target flower and color strains in the entire plot, that is, carry out self-breeding and reserve seeds for the plot, and then select from the obtained target flower and color strains with good agronomic characteristics and a ripening period that is suitable for the ecol...

Embodiment 2

[0019] A breeding method for natural yellow rapeseed, the method comprising the following steps: selecting the main cultivar of Brassica napus with superior plant growth, lodging resistance and strong disease resistance to hybridize with Chinese cabbage with natural yellow flower petals to obtain F0 seeds; after sowing the F0 seeds , select the main inflorescence of an excellent single plant to reserve seeds to obtain F1 seeds, and then carry out mixed sowing of F1 seeds, select plants with the target flower color from F2 at the initial flowering stage to self-bag and reserve seeds, and eliminate single plants of crude oil rapeseed varieties, after many years of continuous Self-separation, until F6 starts to appear in individual plots with the same target flower and color strains in the entire plot, that is, the plots are set up and self-bred to save seeds, and then selected from the target flower and color strains have good agronomic traits and a ripening period suitable for th...

Embodiment 3

[0021] The breeding method of purple-flowered rape comprises the following steps: selecting the main cultivar of Brassica napus with superior plant growth, lodging resistance, and strong disease resistance to cross with Zhuge Cai or purple-flowered radish with purple-flowered petals to obtain F0 seeds; After sowing, select the main inflorescence of an excellent single plant to save seeds to obtain F1 seeds, and then carry out mixed sowing of F1 seeds. From F2, select plants with the target flower color at the initial flowering stage for self-bagging and reserve seeds, and eliminate single plants of crude oil rapeseed varieties. Continuous self-segregation for many years, until F5 began to appear in individual plots with the same target flower and color strains in the entire plot, that is, to set up self-bred seeds for the plot, and then select from the target flower and color strains with good agronomic characteristics and suitable ripening period Ecological conditions in this ...

Abstract

The invention relates to a breeding method for colored-flower rape used for creative agriculture. The method comprises the following steps: selecting a mainly cultivated rape variety with superior growth vigor, medium height, good lodging resistance and disease resistance and large petals as a female parent and a cruciferous plant of varieties with colored petals as a male parent, carrying out hybridization and selecting plants with plant properties similar to those of the female parent rape and flower color properties similar to those of the male parent in segregative generations so as to obtain F0 seeds; sowing the F0 seeds, selecting the main inflorescence of excellent individual plants and reserving seeds thereof to obtain F1 seeds; then carrying out mixed seeding of the F1 seeds; starting with F2 plants, selecting plants with target flower colors in an initial flowering stage, carrying out selfing, bagging and seed reserving, and eliminating individual plants of an original rape flower color variety; and carrying out continuous selfing and separating until in few districts, a variety of a same target flower color appears in the whole district after F5 or F6, and carrying out curtain enclosing, serlfing and seed reserving. With the method provided by the invention, peasants both harvest a product (i.e., rapeseeds) and sell the landscape, and the environment is beautified.
