Abstract

The invention discloses a Nanke No.1 summer radish new variety breeding method. The method comprises the following steps of: taking a Sijiqing summer radish as a female parent; taking Chunbai summer radish as a male parent; crossbreeding the female parent and the male parent; and culturing a summer radish new variety which has the characteristics of early marketing, good benefit, high yield, short production time and long sowing width time by technology such as rogueing and maintaining excellent plants, isolating and planting, breeding improved variety and the like.

Description

A kind of summer radish breeding of new variety method

Technical field:

The invention belongs to a kind of summer radish new variety selective breeding technology, relate in particular to a kind of method that adopts artificial polynary cultivating method cultivation summer radish new varieties.

Background technology:

Summer radish is nutritious, contains various trace elements, amino acid and vitamin, and particularly support one's family A and Vitamin C content are higher, cough-relieving arranged, reduce phlegm, help digestion, pleasant, promote the production of body fluid, remove hot-tempered, the stasis of blood of loosing, detoxify, control and breathe heavily and effect such as diuresis.Radish is a cross pollinated plant, and its genetic material is extremely complicated, again because early spring temperature and ground temperature less stable, radish is bolting very easily by vernalization stage and in advance, therefore selecting the kind of anti-bolting is the key of spring cultivation success.And traditional selection because of still there is bigger difference in its individual inherent quality, therefore causes the radish sensory difference also to be had nothing in common with each other, and growth cycle is slower, and breeding time is longer, and output is lower.

Summary of the invention:

The purpose of this invention is to provide a kind of summer radish breeding of new variety method.The present invention can effectively shorten the cycle of summer radish breed breeding, shortens the breeding time of growing up, and reduces spent manpower and the material resources of summer radish breed breeding, reduces the cost and the risk of breed breeding.

For achieving the above object, technical scheme of the present invention is to work as real estate " Chinese holly " summer radish as female parent, with when real estate " spring is white " summer radish as male parent, hybridize assembly, excellent through the impurity elimination guarantor again, isolate numerous planting, technology such as stock breeding, finally cultivate and have the morning of listing, profitable output height, the summer radish new varieties that growth time is short.

Adopt the summer radish skin of selection seed selection of the present invention thin, green white down on the color of the leather, meat white, the juice fleshiness is crisp, the sweet slightly pungent of distinguishing the flavor of, mouthfeel is good, has good nutritive value.

Embodiment:

Be described in detail the selection of " No. one, Nan Ke " summer radish new varieties below, this method comprises the steps: at least

A, hybridization assembly: it is maternal to adopt local traditional water radish " Chinese holly " to do, and when treating that bolting is bloomed, removes flower pesticide in the flower, and summer radish is covered yarn isolate, and prevents that other flower pesticide from entering.Second day, the pollen on the male parent " spring is white " at florescence to be awarded on the female parent, sexual hybridization after the pollination, is fixed with paper bag.

B, impurity elimination protect excellent: the fleshy root expanding stage pulls out that fleshy root is less, skin is rough, lateral root is many, the individual plant of first bolting, and diseased plant, mix strain and special-shaped strain.

C, results breeding: in time gather in the crops after planting the pod yellow maturity, select ripening rate height, good the reserving seed for planting of growth during results, receive the timely airing in back, threshing, selected, air-dry, under the low temperature drying condition, preserve, be first generation seed.

D, isolate breeding: the high-quality first generation seed of getting after the hybridization is planted, the field of selection to note with the crop in cruciferae distance isolation more than 1000 meters, the field that stubble was not planted brassicaceous vegetable before selecting.Early Febuary, 10cm ground temperature is stabilized in program request more than 5 ℃ on the face of land, 0.5 kilogram of every mu of program request, every cave 3-5 grain, general density 0.8 ten thousand strain/mus, distance between rows and hills 40cm * 20cm, seed level 2-3cm.After planting in time build little shed.

E, selective nursery: 2-3 plants first generation seed, after blossoming and bearing fruit, divides individual plant to gather seed.4-5 gets and gathers in the crops seed last year and plant, and the florescence is isolated management, record breeding time, resistance, yielding ability, adaptability and stability, wait blossom and bear fruit after, divide system's results, " No. one, Nan Ke " new varieties.

F, strain compare: 6-7, and contrast " Chinese holly " is carried out variety test of lines, result of the test:

1826.8 kilograms of per mu yields of the present invention, 1432.2 kilograms of Chinese holly per mu yields increase income 394.6 kilograms than Chinese holly, volume increase 27.6%.

No. one, the section in south " property feature of summer radish:

A, kind property neat and consistent, quality is better.Leaf is that plate leaf, green, leafage are little, about 14 of the numbers of blade; Fleshy root is cylindrical, the long 12-15cm of fleshy root, and thick 5-7cm reveals the body type and buries, and about 2/3rds basset, and skin is thin, green white down on the color of the leather, meat white, the juice fleshiness is crisp, and the sweet slightly pungent of distinguishing the flavor of is to eat raw to good.

B, belong to early-maturing variety, the 50-60 days time of infertility, than precocious 3-5 days of Chinese holly, not only heat resistanceheat resistant, but also cold-resistant, bolting is later, is difficult for the chaff heart, anti-black spot, anti-soft rot, and yielding ability is good, sow single heavy 0.2-0.4 kilogram in spring, the single heavy 0.1-0.3 kilogram of summer sowing, per mu yield 1800-2200 kilogram.Plant height 126.5cm, 8.6 of the effective branches of individual plant, several 201.6 of individual plant effective angle fruit, 6.2 of seeds per pods, thousand kernel weight 9.8 grams, per mu yield seed 70-80 kilogram.

Claims

1. summer radish breeding of new variety method, it is characterized in that: it comprises the following steps:

A, hybridization assembly: it is maternal to adopt local traditional water radish " Chinese holly " to do, when treating that bolting is bloomed, remove flower pesticide in the flower, and summer radish is covered yarn isolate, prevent that other flower pesticide from entering, second day, pollen on the male parent " spring is white " at florescence is awarded on the female parent, sexual hybridization after the pollination, is fixed with paper bag;

B, impurity elimination protect excellent: pull out that fleshy root is less, skin is rough, lateral root is many, the individual plant of first bolting, and diseased plant, mix strain and special-shaped strain;

C, results breeding: in time gather in the crops after planting the pod yellow maturity, select ripening rate height, good the reserving seed for planting of growth during results, receive the timely airing in back, threshing, selected, air-dry, under the low temperature drying condition, preserve, be first generation seed;
