Abstract

The invention discloses a fine thread double-knot type purple thin cayenne pepper selfing technology and belongs to the technical field of plant breeding. Firstly, single purple thin cayenne pepper selfing plants are selected, each is marked by hanging a tag; secondly, flowers in the marked single plants, about to blossom, are selected; household white fine threads are knotted through a double single-knot method, thread rings at one ends are arranged on pedicels in a sleeving mode and slightly tightened, and fine thread sections with the length of 2 cm are reserved at the other ends; the fine threads and the flowers are covered with adhesive label paper, and the upper ends and the lower ends are tightly pinched; fruits with the white thread ring tags hung are harvested at the physiological maturity stage.

Description

A kind of fine rule double-junction purple line green pepper selfing technology

Technical field

The invention discloses a kind of fine rule double-junction purple line green pepper selfing technology, belong to field of plant variety breeding technology.First selected purple line green pepper selfing individual plant also carries out listing mark; Secondly select to have marked in individual plant to be about to open flower; Adopt dual unijunction method by domestic white fine rule formation of knots, the coil of one end is enclosed within bennet, tightens up slightly, and the other end leaves the long fine rule of 2cm; With sticky label paper fine rule and flower wrapped and clutch in top and bottom; Physiological maturity results hang the fruit of white line circle mark.

Background technology

Capsicum belongs to Constantly allogamous plant, and its purifying needs artificial pollination usually.There is shortcomings in said method, one is that pollination speed is slow.From rotation and push flower aside, picking pollen, bread at least need 20-30s in column cap, the operation such as to list; Two is that pollination efficiency is low.Adopt in 4-5 month and manually pollinate, for long red pepper, goat's horn green pepper, line green pepper, screw green pepper, capsicum annum fasciculatum, thin skin green pepper, its success rate can reach more than 80%, once enter even 6-7 month in 5-6 month, pollination efficiency reduces greatly; And manually pimento is pollinated adopting in 4-5 month, its pollination rate is also only 40-50%; Three is easily cause biology hybrid.Artificial pollination many employings dissecting needle or syringe needle, as inoculating tool, when inoculating different capsicum inbred line, easily remain the pollen of previous inbred line at instrument leading portion, easily cause biology hybrid or impure for rear inbred line pollination.

Summary of the invention

Fine rule double-junction purple line green pepper selfing technology has many superiority, and one is artificial and consuming time few; Two is that cost is extremely cheap; Three is be easy to distinguish selfing or non-selfing fruit.According to above-mentioned cognition and experience, we have invented the quick inbred isolation method of purple line green pepper in a kind of greenhouse.

The present invention is achieved in that

A kind of fine rule double-junction purple line green pepper selfing technology, it is characterized in that, include selected purple line green pepper selfing individual plant in described method, select the knotting lopping of flower, thin white threads and pack into bennet, parcel thin white threads and flower and clutch, gather in the crops selfing fruit five steps, reach the object obtaining purple line green pepper selfing fruit fast.Described five steps concrete operations are as follows:

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

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

3. thin white threads knotting lopping pack into bennet: adopt dual unijunction method by domestic white fine rule formation of knots, the coil of one end is enclosed within bennet, tightens up slightly, does not come off be advisable with coil, the other end leaves the long fine rule of 2cm;

4. wrap up thin white threads and flower and clutch: wrapping with the flower of sticky label paper by fine rule long for 2cm and purple line green pepper, being advisable to two circles to wrap up a circle half, at the upper and lower side of flower, label paper being clutched, in case honeybee and other insect enter;

5. selfing fruit is gathered in the crops: physiological maturity results bennet hangs with the selfing fruit of white line circle mark.

Beneficial effect of the present invention: one is artificial and consuming time few.Only need early stage to buy sticky label paper, and without the need to buying dissecting needle or syringe needle, expend 10s at every turn; Two is that cost is extremely cheap.The cost of sticky label paper is low, and 10 expenses spent are about 5 points of; Compare with drop, fine rule price is only its 1/20-1/50.Three is that mark is accurate, short and sweet.Unsuccessful if pollinate, flower can drop by nature, and white coil also can drop thereupon, and successful flower of pollinating is because bennet place hangs with white coil, easily distinguishes.

embodiment:

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

Embodiment:

1) select fine individual plant: in flowering stage, select excellent purple line 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 marked;

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

3) thin white threads knotting lopping pack into bennet: adopt dual unijunction method by domestic white fine rule formation of knots, the coil of one end is enclosed within bennet, tightens up slightly, does not come off be advisable with coil, the other end leaves the long fine rule of 2cm;

4) wrap up thin white threads and flower and clutch: with the sticky label paper of long 2.9cm, wide 2cm, the flower of fine rule long for 2cm and purple line green pepper being wrapped, wrap up in two circles, and the upper and lower side of label paper is clutched;

5) selfing fruit is gathered in the crops: physiological maturity results hang with purple line green pepper fruit 3-4 of white coil, and the time is about 50d to 70 day, and success rate reaches 75-100%.

Claims (1)

1. a fine rule double-junction purple line green pepper selfing technology, it is characterized in that, include selected purple line green pepper selfing individual plant in described method, select the knotting lopping of flower, thin white threads and pack into bennet, parcel thin white threads and flower and clutch, gather in the crops selfing fruit five steps, reach the object obtaining purple line green pepper selfing fruit fast; Described five steps concrete operations are as follows:
