Description
Technical field
The present invention relates to applications, refer in particular to a kind of breeding method of characteristic type watermelon.
Background technique
Seedless watermelon has convenient, the fruit that health-care efficacy is good, nutritive value and economic value are high.According to the United Nations's grain
Agriculture tissue (FAO) statistics, watermelon occupies the 4th in the big fruit in the world ten, and the cultivated area and total output of China's watermelon are equal
It occupies first of the world.Seedless watermelon is prominent because its quality is excellent, commodity is good, class is high, storage tolerance, high financial profit and eurytopicity are strong etc.
Advantage out, currently, seedless watermelon year cultivated area in China's is about 250,000 hm2, is produced by the favor of numerous producers and consumers
For raw direct economic benefit up to 10,000,000,000 yuan or so, seedless watermelon is planted in agricultural sector structure adjustment and rural economic development
In played an important role, createed significant economic benefit and good social benefit.
It is excellent with the continuous improvement of China's overall productivity in agriculture significantly enhanced with living standard of urban and rural population level
Matter, diversification, standardization trend and diversification, multi-level consumption demand increase in rigidity, and people are to seedless watermelon kind
Fruit type size, pericarp surface pattern, interior quality, mouthfeel etc. propose increasingly higher demands.Currently, the nothing of large area plantation
Sub- variety of watermelon is mainly the red flesh class seedless watermelon of casting skin, and Representative Cultivars are (xiangxi watermelon 11) Dongting Lake No.1 seedless watermelon, black
Sweet seedless watermelon etc.；The flower red flesh class seedless watermelon of skin, Representative Cultivars are the new No.1 seedless watermelon in Taiwan and snowy peak flower skin s.m.p west
Melon etc., it is rare for characteristic type Calusena lansium, yellow flesh seedless watermelon kind in the market.Characteristic type Calusena lansium, yellow flesh seedless watermelon product
Innovation is bred as, and to the specializing of fruit market, diversified demand is met, important work is played so as to improve civil plantation
With.Meanwhile developing in a healthy way to the industry for promoting China's seedless watermelon, play bigger impetus.
Summary of the invention
The purpose of the present invention is being improved and being innovated for disadvantage present in background technique and problem, a kind of spy is provided
The breeding method of colour pattern Calusena lansium Huang flesh watermelon.This method directive breeding goes out characteristic, good maternal and male parent, by hybridizing successfully
Select characteristic type Calusena lansium, yellow flesh seedless watermelon.
The present invention the following steps are included:
1, breeding.
A, female parent: a, Breeding Process: female parent is from more than 100 part diploid watermelon materials that are free and introducing both at home and abroad, warp
The directed screening and selfing for spending 4 years 8 generations purify, and obtain the breeding material of more than 20 part characteristic types, therefrom preferably go out 6 middle fruitlets again
Type, pericarp be light yellow, on cover the diploid watermelon material of golden yellow rack gear band；B, colchicin mutagenic treatment: colchicum is used
Alkali prepares mutagenesis concentration 0.25%, 25 DEG C of suitable controlling temperature and mutagenesis period watermelon leaf cells and divides peak period, lures kind
Change processing, induces 4 tetraploid watermelon new materials, optimizes by the purification in 8 generations, directed screening goes out excellent four of Comprehensive Traits
Times body watermelon inbred lines；C, maternal character: female parent be pericarp it is light yellow, on cover golden yellow rack gear band；Flesh color foresythia, section
Good, quality is excellent；Center soluble solid content 12.5% or so, edge 8%；Maturity is early, and growth potential is medium, and disease resistance is strong；Fruit
Real spheroidal, single melon weight 4-5kg, pericarp thickness 1.0cm；The time of infertility 98 days or so.
B, male parent: a, Breeding Process: male parent is from free more than 80 part diploid watermelon material, and preferably Comprehensive Traits are excellent out
Diploid watermelon, be continuously selfed purifying by 11 generations, directed screening goes out to be selfed purifying kind male parent；B, paternal character: male parent
For fruit yellow, on cover yellow serration band；Flesh color foresythia, section is good, and quality is excellent；Center soluble solid content
11.5% or so, edge 9%；Maturity is early, and growth potential is medium, and disease resistance is strong；Spherical fruit, single melon weight 4kg or so, pericarp is thick
0.8cm；The time of infertility 100 days or so.
C, crossbreeding: being combined orientation preparation, variety test and screening for the female parent and male parent that cultivate, fixed
To filtering out triploid seedless watermelon kind and watermelon seed.
2, it begins sowing in good time, nurturing staff: mid-March to early April is sowed, and using feeding block seedlings raising, Nutrition Soil is wanted
Ask loose, be rich in organic matter, no germ, worm's ovum, weeds fine earth；Seedling age 25-30 days, when 2.0-2.5 piece true leaf, can be colonized,
Seedling strain requires the delicate and pretty disease-free spot of blade, and white is covered with nutritive cube；Reinforce the regulation and administration and disease of the epidemic disaster in seedbed when nursery
The prevention and treatment of insect pest.
3, fine transplanting, rational close planting: transplanting in due course, when transplanting, want accurate operation, handle with care, damage root is avoided to hurt stem wound
Leaf；It is required that field planting appropriate depth, is cultivated according to the size fractionation of the seedling age of melon seedling, true leaf；Planting water is watered with when transplanting, and in time
Mulch is covered, promotes melon seedling early raw fast long；There is sub- watermelon as pollinated variety with the diploid for planting 9-10:1 simultaneously.
4, it applies fertilizers scientifically, stringent to prune: growth period controls climing reason rattan, use the training type based on two climing trainings, every plant
Stay fruit 1-2；Using 667m2Dung polluted water 1000kg, cake-shaped rape seed dregs cake 50-70kg are applied, and is equipped with compound fertilizer 25kg and makees base manure；After transplanting
It one week, imposes and mentions seed manure 1-2 times；Climing fertilizer is stretched using the compound rich water of 10kg or so；Swelling melon fertilizer 667m2Apply compound fertilizer 20-
25kg and urea 10-15kg, point 2 to 3 progress, is watered or cave is applied.
5, artificial supplementary pollination.
6, bear fruit section: section of bearing fruit is beared fruit with 12-15 section.
7, high-efficiency low-toxicity safety pesticide is selected, pest and disease damage is prevented；Select highly-effective low-residue pesticide reinforce prevention and treatment, to prevent for
Main, anti-overweight is controlled.
8, picking in time: it is required that 28 days or so after pollination harvest.
In one of the embodiments, the Transplanting Density be 1100 plants or so of protecting field stand cultivation density/
667m2.550 plants of film-mulching cultivation density or so/667m2。
Wherein N, P2O5, K20 total content are 45% when the compound fertilizer applies base manure in one of the embodiments,.
The compound rich water or decomposed loose stool water that mention seed manure and be 0.3% in one of the embodiments,.
The watermelon that breeding method of the present invention cultivates be fruit yellow, on cover yellow serration band, melon pulp cadmium yellow is gorgeous
Calusena lansium Huang flesh seedless watermelon.
Advantages of the present invention and the utility model has the advantages that
The present invention doubles to obtain maternal tetraploid watermelon using colchicin, and selfing purifying obtains male parent, and directive breeding obtains special
Colour pattern Calusena lansium Huang flesh triploid seedless watermelon.The Calusena lansium of the method for the present invention cultivation, yellow flesh seedless watermelon contain green crude fibre, fill out
The blank for having mended current domestic characteristic type seedless watermelon breeding meets the specializing of fruit market, diversified demand, produces
