Description
Technical field
The invention belongs to wheat seed preparation field, it is related to breeding and the cultural method of a kind of high yield wheat resistant to lodging.
Background technology
Wheat is one of three big cereal, almost complete to be used as practicality, only there are about 1/6th and is used as feed, the Yellow Basin and the Yangtze River
It is the area of earliest cultivated wheat in the world, China is to plant one of country of wheat earliest in the world, and wheat is being planted at present
During because climate factor or cultivation step it is improper, cause wheat large area to lodge, have a strong impact on wheat maturation, make
Into a kind of phenomenon of the underproduction.
The content of the invention
It is an object of the invention to provide a kind of breeding method of high yield wheat resistant to lodging, the wheat percentage of earbearing tiller of the kind
It is higher, fringe layer is neat, stalk is elastic good, lodging tolerance is strong, while seed silty, full, and commodity is good, the production of every mu of wheat
Amount is high.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of breeding method of high yield wheat resistant to lodging, is comprised the following steps that：
Step 1：The wheat of place 9916 is taken to carry out sexual hybridization as male parent as female parent, No. 19 wheats of tobacco grower, obtain F1
For wheat hybridizing seed, F1 generation wheat seed is subjected to field and indoor species test, according to fringe layer shape, stalk growing way and resistant to lodging
Ability selects 6 plants of optimal wheats as F2 for seed；
Step 2：For seed be that plant carries out field and indoor species test by individual plant program request by F2, then according to plant height, the ripe phase,
Grain color, plant shape, seedling partly crawl to select 8 plants in field with full grains degree, and indoor species test stays 5 plants to be used as F3 for seed；
Step 3：It is plant that F3 is continued into program request by individual plant for seed, according to anti-freezing property, powder mildew resistance, plant height, strain
Shape is selected, and 4 plants of individual plant for obtaining meeting breeding objective is as F4 for seed；
Step 4：For seed program request it is plant by F4, according to yielding ability, fecundity, plumpness, field and indoor species test choosing
Select 9 plants and obtain F5 for seed, by 9 individual plant kinds in F5 into strain, carry out the identification of field yield and resistance.
The F1 generation shows the characteristics of fringe layer is neat, and character is consistent, and heterosis, hybrid vigor is strong, growth is in great numbers, and stalk is sturdy.
The F3 represent it is existing it is freeze proof, to bar rust, powder mildew resistance is stronger the characteristics of.
The F4 represents existing proper height, tillering ability is strong, spends more the characteristics of how real, strain leaf structure is good.
The F5 is partly crawled on behalf of semi-winterness, seedling, and blade is slightly wider, bottle green, and growing way is strengthened, and seedling growth is sane, cold-resistant
Property is preferable；Tillering ability is medium, and the percentage of earbearing tiller is higher；Plant type half is compact, is lifted on boot leaf, and fringe layer is neat；Plant height 85.9cm, stalk elasticity
Good, lodging tolerance is strong；Spike length square, long awns, white shell, Bai Li, seed silty is full, and commodity is good；Every mu into fringe 42.4
Ten thousand, per solid 32.7 of fringe, 45.9 grams of mass of 1000 kernel；The 221.7 days time of infertility, with compareing the same period of Anhui wheat 52 maturation.
A kind of cultural method of high yield wheat resistant to lodging, step are as follows：
(1) wheat is planted in 8-24 days in October, planting density is every mu of Basic Seedling 120,000~160,000；
(2) base fertilizer is done with mechanical fertilizer to winter wheat, and mechanical fertilizer is imposed in the jointing stage；Preferably, mu applies purity nitrogen 11-
13Kg, 70% makees base fertilizer, and 30% jointing stage imposed, and phosphorus pentoxide 6-8Kg makees base fertilizer and once applied；
(3) wheat is irrigated and the preventing and treating of disease pest and weed：Poured water before wheat cultivation, make the moisture in field not
Less than 70%, carry out winter irrigation after planting, be filled with enough water of once surviving the winter, not only ensured safe overwintering but also prevent the spring frost, cold spell in later spring and in
Drought in later stage endangers, and reaches high yield, the target of stable yields.
Beneficial effects of the present invention：
The wheat breed of the present invention passes through the seed selection in five generations, is selected respectively according to different performance and feature per a generation
Educate, obtained wheat breed has the premium properties of five generation wheats respectively.
The wheat breed of the present invention after seed selection there is seedling partly to crawl, and blade is slightly wider, bottle green, and growing way is strengthened, seedling stage
Growth is sane, and winter resistance is preferable；Tillering ability is medium, and the percentage of earbearing tiller is higher；Plant type half is compact, is lifted on boot leaf, and fringe layer is neat；Plant height,
Stalk elasticity is good, and lodging tolerance is strong；Spike length square, long awns, white shell, Bai Li, seed silty is full, and commodity is good, small per fringe
The features such as yield of wheat is high.
