Description
Technical field
The invention belongs to vegetable breeding technical field more particularly to a kind of breeding sides of brassica plant vegetables cenospecies
Method.
Background technique
Currently, the prior art commonly used in the trade is such that
Brassica plant includes three elementary species (Chinese cabbage, wild cabbage and black mustard) and three aggregate species (cabbage type rapes, leaf mustard
And brassicacarinata).It wherein, applied to production is cabbage type rape, leaf mustard, Chinese cabbage and wild cabbage.
Chinese cabbage and wild cabbage are most important brassicaceous vegetables.Chinese cabbage, wild cabbage and leaf mustard are the Specialty vegetables of south China,
Mainly leaf is used, stem is used and a kind of sedge (ten thousand positive outstanding persons etc., the research progress and prospect of mustard vegetables heterosis utilization, Central China agriculture
Industry college journal, 2018,115-120), " big vast mountain tender flower stalk " well-known throughout the country and " Guangdong cabbage heart " belong to Chinese cabbage.Chinese cabbage, wild cabbage and
Leaf mustard kind appearance morphological characters, breeding time, it is degeneration-resistant in terms of there is diversity and rich, but it is generally pest-resistant,
It is disease-resistant, resistance is poor.
Cabbage type rape is the major oil crops in the world and China.In recent years, cabbage type rape " dish is dual-purpose " or " oil
Vegetable is dual-purpose " (" the dual-purpose effect test of the double 72 oily vegetables in Zhejiang ", Zhejiang Agriculture science, 2002,6,291-294；" different planting pair
The influence of double No. 10 yield in the dual-purpose tender flower stalk of rape oil ", modern agriculture science and technology, the 2016, the 1st phase page 99) to improve the warp of rape
Ji benefit.Compared with Chinese cabbage tender flower stalk, " oily vegetable is dual-purpose "/" dish is dual-purpose " cabbage type rape tender flower stalk have it is high-quality, fry rear color
It is emerald green it is vivid, have the advantages that chewy, faint scent are slightly sweet, meanwhile, tool causes commodity poor there are two major defect: first is that the more a kind of sedges of leaf
Few, a kind of sedge orthostatic is poor；First is that blade is big, petiole is long, vein is coarse, and blade face is uneven, has wax powder, and after picking in a few hours
Blade droops, and read fortune is very poor.
Either Chinese cabbage, wild cabbage and the leaf mustard of oil use or " oily vegetable is dual-purpose " cabbage type rape or vegetables, with business
Change deepening continuously for breed breeding process, Genetic Diversity of Germplasm difference is more and more narrow in species, inhereditary material between species
Exchange it is more and more necessary.In general, by the interspecific hybridization of brassica plant to expand Genetic Diversity of Germplasm.Kind is mixed with
It hands over offspring to be selfed difference of setting seeds, generally requires that offspring could be obtained using embryo Rescue Technology；Characters of progenies separation is serious, and character is stablized
Need many generations；Trait segregation has the skewed popularity of a certain parent, and inhereditary material is very limited between the species that offspring obtains [makees
The introduction of object thremmatology] (2003,2014 innocent chief editors, Chinese agriculture publishing house).Thus, interspecific hybridization is bothersome, time-consuming, is difficult
The genetic resources between species is obtained, the genome of two species may not be polymerize.Breeding cabbage type rape of the present invention and Chinese cabbage,
The interspecific hybrid of cabbage type rape and wild cabbage and cabbage type rape and leaf mustard, cenospecies contain a full set of genome of parents, can
To polymerize the merit of parents.
In conclusion problem of the existing technology is:
(1) prior art lacks the brassica plant vegetable of polymerization cabbage type rape and Chinese cabbage, wild cabbage and leaf mustard genetic resources
The selection of dish cenospecies.
Chinese cabbage, wild cabbage and the leaf mustard kind that the prior art is bred as, the characters such as appearance and breeding time have diversity and enrich
Property, it is suitble to consumer demand, commodity is good, but haves the defects that insect resistace, disease resistance, resistance are poor.
The dish cabbage type rape variety that the prior art is bred as, tender flower stalk have that high-quality, to fry rear bright green vivid, energetically
The advantages that road, slightly sweet faint scent, but have the defects that read fortune is very poor, commodity is poor, show themselves in that the more a kind of sedges of leaf are few, a kind of sedge orthostatic is poor,
Blade is big, petiole is long, and vein is coarse, and blade face is uneven, has wax powder, and a few hours intra vane droops after picking.
The prior art expands the genetic diversity of brassica plant germ plasm resource by interspecific hybridization, and there are after interspecific hybridization
In generation, is selfed the defects of poor, trait segregation is serious, trait segregation has skewed popularity, and character stablizes heredity needs many generations of setting seeds.
(2) kind that the prior art is bred as only has the gene of one cabbage type rape, Chinese cabbage, wild cabbage or leaf mustard species
Group hereditary information, simultaneously containing cabbage type rape and Chinese cabbage, cabbage type rape and wild cabbage or cabbage type rape and leaf mustard
Genome genetic resources.
(3) kind that the prior art is bred as can be selfed or flower bud phase stripping flower bud selfing harvests seed, behind generation separation group
Individual choice can be carried out in body, thus kind cannot be effectively protected.
Solve the difficulty of above-mentioned technical problem:
For a long time, plantation cabbage type rape is mainly used for harvesting seed oil expression, and plantation Chinese cabbage, wild cabbage and leaf mustard are mainly used
Make vegetables in harvest trophosome.Blade is big, the higher cabbage type rape variety of plant and branch position, often disease resistance resistant to lodging
By force, photosynthetic efficiency is high, grain yield is high；Chinese cabbage, wild cabbage and leaf mustard, exterior quality is good, more axillary buds, sees lover, and commodity is good, by
Consumer likes.Therefore, long-term artificial selection, the property of the cabbage type rape variety of incubation and Chinese cabbage, wild cabbage and leaf mustard kind
Shape difference is big.In addition, the biological characteristics of brassica plant determine that the cabbage type rape of tetraploid is whiter than its diploid parents
Dish and wild cabbage have trophosome advantage, have strong resistance, pest-resistant disease resistance.Thus, cabbage type rape is as vegetables, and white
Dish, wild cabbage and leaf mustard are more advantageous, also there is disadvantage.It polymerize cabbage type rape and Chinese cabbage, wild cabbage and leaf mustard genetic resources, will has
Hope the vegetable variety for being bred as that yield is high, commodity is good.The method that current rape species genetic resources swaps is that kind is mixed with
It hands over, i.e., hybridizes Wild cabbage type with leaf mustard, Chinese cabbage or wild cabbage, plant cenospecies, bagging selfing is carried out to hybrid plant, after selfing
In generation, is selected.Since Interspecific Hybrids selfing is set seeds, poor, trait segregation is serious, trait segregation has skewed popularity, not only needs
It spends many generations that could stablize, and the character for stablizing plant is often partial to a certain parent, is difficult to polymerize parents' advantage.
Solve the meaning of above-mentioned technical problem:
The present invention creates interspecific hybrid, success using cabbage type rape sterile line and Chinese cabbage, wild cabbage and leaf mustard self-mating system
Ground selects brassica plant vegetables cenospecies, enriches brassica plant vegetables, will promote Cruciferae Brassica genus vegetable
The breeding and utilization of dish new varieties.
