Problems solved by technology

[0004] The time for using grafted seedlings to identify seed offspring can be shortened to 4-5 months, but each grafted seedling can still only identify one hybrid offspring. Faced with a large number of hybrid seeds, breeders need to carry out a large number of large-scale, large-scale The seed selection work, the seed selection nursery occupies a large area, the cost of breeding labor is high, and the screening efficiency is low, which still cannot change the status quo of slow progress in passion fruit hybrid breeding.

Embodiment 1

[0033] A method for improving passion fruit breeding efficiency, comprising the steps of:

[0034] (1) Construction of one-line single-line cultivation frame: vertically bury support rods with a height of 180cm at intervals of 3.0m in the planting border, and the height of the support rods from the ground is 160cm, and then connect and fix each support rod with a steel wire rope, that is, It can form a one-line single-line cultivation frame;

[0035] (2) selection and field planting of the mother plant: select the healthy seedlings of the passion fruit variety (yellow variety) resistant to stalk rot, and begin to plant the mother plant in October-November; the planting density of the mother plant is 1m × 1.0m planting;

[0036] (3) Cultivation of the mother plant: After the passion fruit mother plant is planted, the main vine is induced to be put on the shelf along the supports such as bamboo poles and ropes, and then the main vine is guided to extend in one direction of the ...

Embodiment 2

[0042] A method for improving passion fruit breeding efficiency, comprising the steps of:

[0043] (1) Construction of one-shaped single-line cultivation frame: vertically bury support rods with a height of 190cm at every interval of 3.0m in the planting border, and the height of the support rods from the ground is 170cm, and then connect and fix each support rod with a steel wire rope, that is, It can form a one-line single-line cultivation frame;

[0044] (2) Selection and field planting of the mother plant: select the grafted seedlings (yellow variety) resistant to stalk rot, and begin to plant the mother plant in October-November; the planting density of the mother plant is planted at 1m × 1.5m with the spacing between rows;

[0045] (3) Cultivation of the mother plant: After the passion fruit mother plant is planted, the main vine is induced to be put on the shelf along the supports such as bamboo poles and ropes, and then the main vine is guided to extend in one directio...

Embodiment 3

[0051] A method for improving passion fruit breeding efficiency, comprising the steps of:

[0052] (1) Construction of one-shaped single-line cultivation frame: vertically bury support rods with a height of 185cm at intervals of 3.0m in the planting plot, and the height of the support rods from the ground is 165cm, and then connect and fix each support rod with a steel wire rope, that is, It can form a one-line single-line cultivation frame;

[0053] (2) Selection and field planting of the mother plant: select the healthy seedlings (yellow variety) of the passion fruit variety resistant to stalk rot, and begin to plant the mother plant in October-November; the planting density is 1m * 1.2m with the row spacing of the plants planting;

[0054] (3) Cultivation of the mother plant: After the passion fruit mother plant is planted, the main vine is induced to be put on the shelf along the bamboo pole, and then the main vine is guided to extend in one direction of the inline single...

Abstract

The invention provides a method for improving passion fruit breeding efficiency, belongs to the technical field of passion fruit breeding, and aims to identify a plurality of filial generation singleplants of passion fruit plant lateral vines at the same time by utilizing a linear single-line cultivation frame, so that not only can the influence of single plant death and loss caused by infectionof stem rot in the planting and growth process of the hybrid seedling progeny be avoided, but also the juvenile phase of seedlings can be effectively shortened, the filial generation seedlings are promoted to blossom and bear fruits in advance to identify botanical traits and fruit quality performance of the filial generation, the purpose of accelerating the breeding process is achieved, the spaceof a breeding site is greatly saved, the labor cost is reduced, the passion fruit breeding efficiency is effectively improved, and technical support is provided for promoting the passion fruit breeding level in China.

Description

technical field [0001] The invention belongs to the technical field of passion fruit breeding, in particular to a method for improving the breeding efficiency of passion fruit. Background technique [0002] Passion fruit (Passiflora edulis Sims), scientific name Passiflora, Passiflora, Passiflora genus, is a perennial evergreen vine berry fruit tree in the tropics and subtropics. Passion fruit is a fruit of high economic value. The fruit can be eaten fresh or processed into juice. Because of its strong and special aroma, it is loved by consumers all over the world. The supply of high-quality fresh passion fruit has been in short supply in domestic and foreign markets. In the past ten years, passion fruit has become a popular and characteristic fruit tree with priority development in my country, and the cultivated area continues to increase. At present, the first main variety in my country and even in Southeast Asia is still the hybrid variety "Tainong No. 1" bred by Mr. Lin...
