Problems solved by technology

Planting performance: curds are purple-red, thinner and looser, not very flat, about 0.3-0.5kg in weight, about 135 days in growth period, only a small amount can be harvested before winter, and cannot be directly used in production. figure 2
Obviously, it is difficult to achieve the purpose of breeding with only two materials

Embodiment 1

[0041] This example is based on one of the two-way back-setting breeding technology schemes, the selection and breeding of the self-incompatible line Zi a12:

[0042] step one:

[0043] The self-developed middle purple cauliflower self-defined incompatibility line 97·f3-7-3-1a3 was used as the female parent, and the purple cauliflower material Ziyin-1 introduced from Denmark was used as the male parent to obtain F1 hybrids; the second In 2009, the F1 generation hybrid was used as the female parent, and Ziyin-1 was used as the recurrent parent to carry out backcrossing, and the backcrossing material BC1 was obtained;

[0044] Step two:

[0045] In the next generation, BC1 will be planted in a group of about 250 plants. When the curds grow in mid-October, field selection will be carried out. The selected single plant requires that the curds are all purple, larger and thicker, and the growth period is 80-90 days. disease, selected about 20 plants, moved them into the greenhouse w...

Embodiment 2

[0060] In this embodiment, according to the two-way backcross breeding technical scheme, another relatively self-incompatible line purple b 2 -1 option to breed:

[0061] step one:

[0062] In order to cause a large difference in traits between the progeny materials in Example 1, the self-incompatibility line Zi Pa of purple cabbage among varieties was selected as the female parent in this example, and the self-incompatibility line 97. f 3 -7-3-1a 3 Crossbreed for male parent to obtain hybrid material F1;

[0063] Step two:

[0064] Due to the large differences in genotypes due to hybridization among varieties, the above-mentioned F1 showed strong hybrid vigor, and the curd was just a purple-red flower core. 3 -7-3-1a 3 Carry out backcrossing for the reincarnated parent to obtain backcrossed offspring BC 0 , continue backcrossing in the following year and get BC 2 ;

[0065] Step three:

[0066] Put the above BC 2 Plant a group of about 350 plants, and make detailed...

Embodiment 3

[0077] In this example, according to the two-way backcross breeding technology scheme, self-incompatible lines with large differences in traits were selected and bred in two different directions, and hybrid varieties with excellent agronomic traits were bred on this basis.

[0078] Proceed as follows:

Abstract

The invention relates to the field of crop cultivation, in particular to a purple cauliflower hybrid seed cultivation method. A mediummorchid parent 97.f3-7-3-1a3 is taken as a main body parent to be respectively hybridized with purple-flower vegetable material ZiYin-1 with Europe consanguinity, variant distant related ZiPa (purple cabbage) according to a seed cultivation object design technical scheme by use of existing germplasm resources; backcross or continuous backcross is performed on the F1 generation, individual selection and autocopuation in a net chamber are performed BC1, BC2 and descendants by virtue of a pedigreen method according to the seed cultivation object, so that two stable-character and good-regularity self-incompatible lines are line-bred after 6-7 generations; the hybrid F1 generation has great heterosis and has yield which is increased by not less than 80% than those of parents, and ball flowers are purple red in color, compact, gorgeous and glossy, taste crisp, tender and sweet if being not cooked, taste delicious, tasty and refreshing if being cooked, and are named as ZIJING-1.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a method for breeding purple cauliflower hybrid varieties. Background technique [0002] Cauliflower is a variety of Brassica oleracea, scientific name Brassica oleracea L.var.botrytis L., evolved from cabbage, and its origin is in the Mediterranean region of Europe. Purple cauliflower is a rookie in the cauliflower family and a new creation in cruciferous breeding in recent years. Its curds are bright purple and taste good. [0003] More importantly, in addition to the vitamin C rich in common cauliflower, purple cauliflower also contains more special biologically active substances - anthocyanins, which are recognized by the nutrition and medical circles as having anti-aging and anti-tumor properties. , lowering blood pressure and other effects. To meet the increasing demand of people for natural nutritional and health food in the world, Japan, Denmark, the Netherlands, and the...
