Firstly, a single purple goat horn pepper selfing plant is selected and marked by hanging a plate; secondly, flowers, about to bloom, in the marked single plant are selected; thirdly, the flowers are wrapped by non-setting adhesive label paper, and the label paper is clenched at the upper ends and the lower ends of the flowers; the flowers are marked by hanging plates; fruits marked by the hanging plates are harvested in the physiological maturity stage.

Description

The purple quick inbred isolation method of Cornu Caprae seu Ovis green pepper in a kind of greenhouse

Technical field

The invention discloses the purple quick inbred isolation method of Cornu Caprae seu Ovis green pepper in a kind of greenhouse, belong to field of plant variety breeding technology. First selected purple Cornu Caprae seu Ovis green pepper selfing individual plant also carries out listing mark; Next selects, and labelling individual plant is interior is about to open flower; With sticky label paper, flower wrapped and clutch in top and bottom; By this flower listing mark; The fruit of physiological maturity results listing mark.

Background technology

Fructus Capsici belongs to Constantly allogamous plant, and its purification typically requires artificial pollination. There is shortcomings in said method, one is that pollination speed is slow. From rotating and push aside flower, picking pollen, bread at least need 20-30s in stigma, the operation such as list; Two is that pollination efficiency is low. Adopting in 4-5 month and manually pollinate, for Capsicum frutescens L��Var��1o m Bail, Cornu Caprae seu Ovis green pepper, line green pepper, screw green pepper, capsicum annum fasciculatum, thin skin green pepper, its success rate is up to more than 80%, once enter even 6-7 month in 5-6 month, pollination efficiency is substantially reduced; And manually Fructus Capsici is pollinated adopting in 4-5 month, its pollination rate is also only 40-50%; Three is be easily caused biology hybrid. Artificial pollination many employings dissecting needle or syringe needle, as inoculating tool, when different Fructus Capsici selfing linies are inoculated, easily remain the pollen of previous selfing line at instrument leading portion, are easily caused biology hybrid or impure for the pollination of later selfing line.

Summary of the invention

In a kind of greenhouse, the quick inbred isolation method of purple Cornu Caprae seu Ovis green pepper has many superioritys, and one is artificial and consuming time few; Two is that cost is extremely cheap; Three are easy to distinguish selfing or non-selfing fruit. According to above-mentioned cognition and experience, we have invented the purple quick inbred isolation method of Cornu Caprae seu Ovis green pepper in a kind of greenhouse.

The present invention is achieved in that

The purple quick inbred isolation method of Cornu Caprae seu Ovis green pepper in a kind of greenhouse, it is characterized in that, described method includes selected purple Cornu Caprae seu Ovis green pepper selfing individual plant, select flower, parcel flower and clutch, flower listing mark, results five steps such as selfing fruit, reach quickly to obtain the purpose of purple Cornu Caprae seu Ovis green pepper selfing fruit. Five described step concrete operations are as follows:

1. selected individual plant: be selected in and need the purple Cornu Caprae seu Ovis green pepper individual plant of selfing and carry out listing mark;

2. flower is selected: in selected labeled individual plant, be about to open flower, based on the flower to the female bucket of green pepper or four;

3. parcel flower clutching: wrapped by the flower of purple Cornu Caprae seu Ovis green pepper by sticky label paper, is advisable to two circles wrapping up a circle half, and label paper is clutched by the upper and lower side at flower, in case Apis and other insecticide enter;

4. flower listing mark: the bennet place drop at parcel flower carries out listing and dating;

5. results selfing fruit: physiological maturity results bennet has the fruit of drop.

Beneficial effects of the present invention: one is artificial and consuming time few. Early stage has only to buy sticky label paper, without buying dissecting needle or syringe needle, expends 10s every time; Two is that cost is extremely cheap. The cost of sticky label paper is low, and 10 expenses spent are about 5 points of. Three is that labelling is accurate, short and sweet. Unsuccessful if pollinating, flower can drop by nature, and successful flower of pollinating is because bennet place hangs with drop, it is easy to distinguishes.

Detailed description of the invention:

Below in conjunction with specific embodiment, the present invention is conducted further description;

Embodiment:

1) select fine individual plant: in florescence, select excellent purple Cornu Caprae seu Ovis green pepper individual plant according to breeding objective, and hang up red festoons at its place of Shi Huajiewei main split and mould board and be marked;

2) flower is selected: in selected labeled individual plant, be about to open 4 four female bucket flower;

3) wrap up flower and clutch: the sticky label paper of long 2.9cm, wide 2cm being encased flower, wraps up in two circles, and the upper and lower side of label paper is clutched;

4) labelling flower: the drop with the time is suspended on the flower after parcel;

5) results selfing fruit: physiological maturity results hang with the purple Cornu Caprae seu Ovis green pepper fruit 4 of drop, and the time is about 55d to 70 day, and success rate reaches 100%.
