Abstract
The invention discloses a fine-line two-knot type milky yellow sweet pepper selfing technology, and belongs to the technical field of plant breeding. The method comprises the steps that milky yellow sweet pepper selfing individual plants are selected and marked with hanging tags; flowers to be opened in the marked individual plants are selected; domestic white fine lines are knotted into loops through a dual single-knot method, pedicels are sleeved with one ends of the line loops and slightly tightened, and fine lines with the length of 2 cm are reserved at the other ends of the line loops; the fine lines and the flowers are wrapped by sticky label paper, and the upper ends and the lower ends are clenched; fruits marked with the hanging white loop rings are harvested in the physiological mature stage.
Description
Technical field
The invention discloses a kind of fine rule double-junction milk yellow Fructus Capsici selfing technology, belong to field of plant variety breeding technology.First selected milk yellow Fructus Capsici selfing individual plant also carries out listing mark；Next selects, and labelling individual plant is interior is about to open flower；Adopting 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 fine rule of 2cm length；With sticky label paper, fine rule and flower are wrapped and clutch in top and bottom；Physiological maturity results hang the fruit of white line circle labelling.
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
A kind of fine rule double-junction milk yellow Fructus Capsici selfing technology 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 quick inbred isolation method of milk yellow Fructus Capsici in a kind of greenhouse.
The present invention is achieved in that
A kind of fine rule double-junction milk yellow Fructus Capsici selfing technology, it is characterized in that, described method includes selected milk yellow Fructus Capsici selfing individual plant, selects the knotting lopping of flower, thin white threads and pack into bennet, parcel thin white threads and flower and clutch, gather in the crops five steps of selfing fruit, reach quickly to obtain the purpose of milk yellow Fructus Capsici selfing fruit.Five described step concrete operations are as follows:
1. selected individual plant: be selected in and need the milk yellow Fructus Capsici 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. thin white threads knotting lopping pack into bennet: adopting 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 fall off with coil and is advisable, and the other end leaves the fine rule of 2cm length；
4. parcel thin white threads and flower clutching: wrap with the flower of the sticky label paper fine rule by 2cm length and milk yellow Fructus Capsici, 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；
5. results selfing fruit: physiological maturity results bennet hangs with the selfing fruit of white line circle labelling.
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；Comparing with drop, fine rule price is only its 1/20-1/50.Three is that labelling is accurate, short and sweet.Unsuccessful if pollinating, flower can drop by nature, and white coil also can drop therewith, and successful flower of pollinating is because bennet place hangs with white coil, 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 milk yellow Fructus Capsici 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) thin white threads knotting lopping pack into bennet: adopting 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 fall off with coil and is advisable, and the other end leaves the fine rule of 2cm length；
4) wrap up thin white threads and flower and clutch: with the sticky label paper of long 2.9cm, wide 2cm, the fine rule of 2cm length and the flower of milk yellow Fructus Capsici being wrapped, wrap up in two circles, and the upper and lower side of label paper is clutched；
5) results selfing fruit: physiological maturity results hang with milk yellow Fructus Capsici 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 milk yellow Fructus Capsici selfing technology, it is characterized in that, described method includes selected milk yellow Fructus Capsici selfing individual plant, selects the knotting lopping of flower, thin white threads and pack into bennet, parcel thin white threads and flower and clutch, gather in the crops five steps of selfing fruit, reach quickly to obtain the purpose of milk yellow Fructus Capsici selfing fruit；Five described step concrete operations are as follows:
