The first step, parent's plantation and selection.Parent's sowing time is to be advisable between October 15 to 20, select with this understanding the good material of moderate yield traits at heading stage as parent, hybridize, the possibility of choosing like this individual plant that sowing time from early October to early November is all adapted in its offspring is just larger.When hybridizing, consider the disease resistance between parent simultaneously, the reasonable coordination of plant height, plant type, yield level, this is in order to increase the probability of the individual plant appearance in its offspring with a plurality of ideal character assemblys.
Second step, F
1plantation and selection.Due to F
1in heterozygous state, added new nuclear genetic material, kytoplasm may be inharmonious, therefore more responsive to low temperature to panicle spike primordium differentiation stage, F
1do not carry out Gene Isolation, restructuring and exchange, each individual contained genetic material is substantially the same, also almost not different to the resistance of low temperature, so F
1can not broadcast too early, at the beginning of 11 months, be advisable, sowing too early very easily causes F
1solid too poor and whole combination is superseded.
The 3rd step, F
2plantation and selection.Compare F with F1
2there is portion gene separation, restructuring and exchange, between individuality, also occurred larger difference, but because Gene Isolation, restructuring and exchange are also incomplete, so in order to obtain the combination of more a plurality of ideal characters, so F
2can not broadcast too early, to be advisable about October 20.
The 4th step, F
3plantation and selection.With F
2compare F
3the process of Gene Isolation, restructuring and exchange carry out more fully, the combination of a plurality of ideal characters of this appearance just may occur, F
3sowing time can further shift to an earlier date, in October 10 sowing, be advisable, can eliminate the type that those not too adapt to early sowing like this.
The 5th step, F
4plantation and selection.With F
3compare F
4the process of Gene Isolation, restructuring and exchange carry out more fully, the basicly stable moulding of individuality, the possibility that continues variation diminishes, so the emphasis in F4 generation is to select.Because this F3 selects under early sowing condition, so the date of seeding of F4 is advisable with late sowing, date of seeding is early November, under this this condition, select the adaptability of date of seeding, disease resistance, plant height and plant type etc., and initial option yield traits.
The 6th step, F
5plantation and selection.F
5in generation, gets back to October 10 again and plants, under early sowing condition to its date of seeding adaptability, disease resistance, plant height and plant type etc. select, and initial option yield traits, and can obtain some more stable strains and more seed.
The 7th step, F
5each processing and output is from generation to generation identified later.Owing to having obtained strain, its seed is more, can have the yield trials of repetition, and the output that can simultaneously carry out under different sowing dates condition is identified.This process can be carried out two to three years repeatedly, until that select stable high yield and different sowing dates is had to better adaptive new lines.Foregoing has been set forth the process and method with crossbreeding seed selection eurytopicity High-Yield Wheat Cultivar, and this process and method is also applicable to the seed selection of other breeding technique and other crop eurytopicity new varieties.
The selection that carries out eurytopicity High-yield Wheat new varieties by shuttling back and forth between different sowing dates of the present invention, the method comprises the following steps: between annual October 15 to 20, sow parent, and select the heading stage moderate good material of yield traits as parent in Second Year, hybridize; At the beginning of annual 11 months to F
1sowing; About annual October 20 to F
2sowing; Annual sowing on October 10 F
3, eliminate the type that those not too adapt to early sowing; Annual early November sowing F
4, select the adaptability of date of seeding, disease resistance, plant height and plant type etc., and initial option yield traits; Annual October 10 is to F
5sowing, to F
5date of seeding adaptability, disease resistance, plant height and plant type etc. select, and initial option yield traits, obtains some more stable strains and more seed; F
5each processing and output is from generation to generation identified later.The shuttling back and forth between different sowing dates of passing through in the present invention carried out the selection of eurytopicity High-yield Wheat new varieties, by the seed selection repeatedly between different sowing dates, so just increased the adaptability of middle material selection to different sowing dates, also just met different cropping patterns to times different requirements, increased the extent of spreading amd application, not only can be used for double cropping system, but also can be used for triple-cropping system, and even may when first arrival in October is at the beginning of 11 months, whenever sow and obtain optimal production.Shuttle breeding between the different sowing dates in same place, fundamentally solve the requirement to wheat different sowing dates of complicated wheat planting that the Sichuan Basin and surrounding area form because of special ecological condition and complicated topography and geomorphology, there is higher theoretical level and application prospect widely.Shuttle breeding cost between the different sowing dates in same place is relatively low, because the shuttle breeding of different location, breeder will hurry back and forth between different location, so both increase cost, also delay very much.
Foregoing has been set forth the process and method with crossbreeding seed selection eurytopicity High-Yield Wheat Cultivar, and this process and method is also applicable to the seed selection of other breeding technique and other crop eurytopicity new varieties.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
