Problems solved by technology

However, the use of self-incompatible lines for seed production requires a lot of manpower and time for parental breeding (through artificial pollination at the bud stage), which is very costly, and the promotion area is limited by the number of seeds produced.
What is more unfavorable is that the long-term continuous self-trading of the parents will cause the vitality to degenerate, so that some excellent characters will be lost, and the hybridization rate of hybrids is difficult to reach 100%.
The use of dominant nuclear male sterile lines for seed production is cumbersome, complicated and difficult to popularize

Embodiment Construction

[0036] In this example, the standard code of white cauliflower cytoplasmic male sterile line used as female parent for the first time is CMS05-6, the standard code of excellent and stable DH strain is 03-12, and the standard code of purple cauliflower cytoplasmic male sterile line is CMS08- 2, the excellent and stable DH strain standard code number 09-16 can be purchased on the market as required (for example, purchase from Zhenjiang Ruifan Agronomy Co., Ltd., address No. 112, Ninghang Road, Jurong City, Jiangsu Province), the present invention is practical feasible.

[0037] Such as figure 1 As shown, the breeding process of the present embodiment is as follows: in the first step, the loose type white cauliflower is selected to have erect plants, green leaves, semicircular curds, slightly flat tops, pine curds, 18-24 cm long flower branches, and the color of the bulbs. Milky white, fine buds, single bulb weight 700-800g, normal development of flower organs, thick yellow peta...

Abstract

The invention relates to a breeding and cultivating method for a plant, in particular relates to a breeding and cultivating method for loose purple cauliflowers, and belongs to the technical field of plant cultivation. The breeding and cultivating method comprises the steps of hybridizing a loose purple cauliflower breeding material with a semi-compact purple cauliflower breeding material to obtain seeds F1, and selfing single strains with high comprehensive agronomic characters after the seeds F1 are sowed to obtain seeds F2; performing microspore culture on single loose purple cauliflowers through flower buds suitable for the microspore culture from the mononuclear edging stage to the double-core early stage to grow a large number of normal regenerated plants, selfing excellent DH plants of the loose purple cauliflowers to obtain a loose purple cauliflower excellent DH strain 03-12 serving as a recurrent parent which is hybridized with a cauliflower cytoplasmic male sterility source material CMS05-6, performing five generations of backcross transformation and selection to form a cytoplasmic male sterile line CMS08-2, and hybridizing the DH strain serving as a parent with the excellent cytoplasmic male sterile line CMS08-2.

Description

technical field [0001] The invention relates to a method for breeding and cultivating plants, in particular to a method for breeding and cultivating loose purple cauliflower, belonging to the technical field of plant cultivation. Background technique [0002] Loose purple cauliflower is more and more popular because of its compact plant type, short growth period, green leaf color, purple flower stems and flower buds, loose flower balls, long flower stems, good taste, high commodity value, strong stress resistance and disease resistance. The more popular it is with growers and consumers. Loose purple cauliflower is mainly eaten with fat and tender flower buds and flower stems. The flower buds and flower stems are purple and beautiful, the meat is crisp and tender, the flavor is sweet, rich in nutrition, rich in vitamins A, B, C, E, protein, anthocyanins, minerals substances and other nutrients. It combines the advantages of loose cauliflower, while removing the disadvantage...
