Description
Technical field
The invention belongs to wheat breeding technical fields, more particularly to a kind of method of wheat crossbreeding.
Background technique
Wheat is always traditional one of the crop planting kind in China, and the life of the people be unable to do without flour, crops
It plants and be unable to do without wheat, however yield is always an important factor for restricting its development.China's wheat planting is based on winter wheat, seedling
Phase low temperature is overwintering, be easy to cause wheat growth impaired if temperature is too low, influences subsequent growing way, reduces yield, must so having
Cultivate freeze proof, high yield wheat breed.
Traditional wheat breeding process is natural hybridization or selfing, until new varieties are cultivated, but this method is educated
Kind time length, low efficiency, cause breeding repetitive rate low, and breeding unstable result keeps the development of wheat breeding process limited, therefore has
A kind of method for breeding wheat can be improved wheat yield, freeze proof, anti-evil and vitality tanacity to be studied.
Summary of the invention
The purpose of the present invention is to provide a kind of method of wheat crossbreeding, by by Resistant and anti-fall wheat and base
Because the Wild Wheats after mutation are hybridized, is then hybridized again with the wheat of high and stable yields, cultivated freeze proof, insect pest
With the High-yield Wheat of vitality tanacity, solve that existing wheat is freeze proof, insect pest ability difference and low output, adaptability difference are asked
Topic.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions：
The present invention is a kind of method of wheat crossbreeding, is included the following steps：
(1) Resistant for being suitable for local plantation and anti-fall wheat seed is selected to carry out rudiment culture indoors, in wheat
The period of vernalization filters out still germinable wheat seed within the temperature range of -10 DEG C~2 DEG C, then by it in disease sense and salt
It is planted and is grown under the conditions of alkali, and obtain F1 generation seed；
(2) using F1 generation seed as male parent, Wild Wheats is selected to be hybridized for female parent, and obtains F2 for seed；
(3) F2 is subjected to rudiment culture for seed indoors, in the wheat vernalization stage, filters out the temperature at -10 DEG C~2 DEG C
Spend still germinable wheat seed in range, then by its disease sense and it is saline and alkaline under the conditions of planted and grown, and obtain F3
For seed；
(4) select the wheat seed of high and stable yields for female parent, using F3 for seed as male parent, hybridized, and harvest F4 generation
Seed；
(5) F4 is subjected to rudiment culture for seed indoors, in the wheat vernalization stage, filters out the temperature at -10 DEG C~2 DEG C
Spend still germinable wheat seed in range, then by its disease sense and it is saline and alkaline under the conditions of planted and grown, and obtain F5
For seed；
(6) under field conditions (factors), F5 is normally sowed for seed, and is selfed F5 in wheatland for seed, crop height,
The strong new varieties of disease resistance.
Further, Wild Wheats are obtained after gene mutation, and after carrying out the plantation of at least two generations in the step (2)
Wheat breed.
Further, wheat seed carries out seed soaking before carrying out rudiment culture indoors in the step (1).
It further, further include being applied fertilizer and being recorded growth shape for the growth course of seed to F5 in the step (6)
Condition.
The invention has the advantages that：
1, the present invention is trained by hybridizing Resistant and anti-fall wheat seed with the Wild Wheats after gene mutation
F2 is brought out for seed, and F2 is planted for seed in disease sense and saline and alkaline condition, improves F2 for the insect pest ability, freeze proof of seed
Ability and alkali resistant ability, and F2 is strengthened for the adaptive capacity to environment of seed.
2, the present invention feels for seed in disease by hybridizing F3 with the wheat seed of high and stable yields for seed, and by F4
It is planted with saline and alkaline condition, improves F4 for the yield and growth stability of seed.
3, method of wheat crossbreeding of the present invention with natural hybridization or selfing compared with, cultivate the time it is short, seed it is each
Aspect performance is high, and people is suitble to carry out popularizing planting.
