Embodiment 1

[0037] A method for artificial detasseling and selfing of indoor planting chicory, the specific steps are as follows:

[0038] S1: Parental selection

[0039] 1.1 Choose the champagne chicory planted in the plant factory module as the parent of cross-pollination, and the cultivation time is about 50-60 days to enter the flowering period.

[0040] 1.2 The main character of the champagne chicory is that it is suitable for planting in a plant factory and has a high yield, and its fresh grass yield per unit area is 2.6 times that of the Opel chicory fresh grass yield with higher yield when planted in the field.

[0041] S2: Selection of female parent inflorescence

[0042] 2.1 In the cultivated champagne chicory plants, select 6 plants that have good growth and meet the breeding objectives, and select strong flower branches and inflorescences growing from side branches, wherein, the selection period of the inflorescences is the inflorescences to be opened from side branches growt...

Embodiment 2

[0057] A method for artificial detasseling and selfing of indoor planting chicory, the specific steps are as follows:

[0058] S1: Parental selection

[0059] 1.1 Select the general chicory planted in the plant factory module as the parent of cross-pollination, and the cultivation time is about 50-60 days to enter the flowering period.

[0060] The main characters of the general chicory described in 1.2 are that it is suitable for planting in a plant factory and has good growth and consistent plant type.

[0061] S2: Selection of female parent inflorescence

[0062] 2.1 Select 6 plants that grow well in the cultivated chicory plants and meet the breeding objectives, and choose strong flower branches and inflorescences growing from side branches, wherein the selection period of the inflorescences is the inflorescences to be opened from side branches growth, and It is advisable when the purple tongue-shaped flowers of its flower organs have just exposed their petals.

Abstract

The invention discloses an artificial emasculation and breeding method for indoor planting of cichorium intybus. The floral organ characteristics of the cichorium intybus are combined; and the artificial emasculation and breeding method is simple and easy to operate, has no pollen residue and no damage to styles during emasculation, and provides technical support for breeding of excellent varieties of cichorium intybus plants. The cultivation of new cichorium intybus varieties with excellent characters is facilitated, and germplasm resources of the cichorium intybus plants are enriched. Meanwhile, the problem that the cichorium intybus plants are infertile during selfing during indoor planting is solved, and the defects that artificial castration styles of the cichorium intybus are prone to being damaged, castration is not thorough, pollen residues exist, and manual crown cutting and sprayer flushing is complex in operation and long in consumed time are overcome.

Description

technical field [0001] The invention relates to the technical field of compositae breeding, in particular to an artificial detasseling and breeding method for indoor planting chicory. Background technique [0002] Chicory is a perennial herb of the genus Chicory in the Compositae family, and is one of the main forage grasses and vegetables widely used at home and abroad. As a fresh pasture, chicory is rich in nutrition, with high content of crude protein, crude fiber, nitrogen-free extract and crude ash. In addition, forage chicory is rich in minerals, has good palatability, high forage yield and long usable period. Chicory leaves are tender in texture and have a good taste, and are liked by cattle, sheep, pigs, chickens, and rabbits. In addition, chicory has strong adaptability and strong disease resistance. Its main component, inulin, is a pure natural extract of plant roots and can be used as a natural food ingredient. [0003] In our country, chicory is mostly introdu...
