A device for alfalfa haploid is cultivateed
Technical Field
The utility model relates to a technical field of agricultural production equipment specifically is a device that is used for alfalfa haploid to cultivate.
Background
Haploid breeding has huge commercial application value, haploid plants are generated by utilizing haploid induction, and then natural or artificial doubling is carried out, so that homozygous breeding materials can be obtained within two years, the selection process can be remarkably accelerated, and the breeding period can be shortened. Alfalfa (Medicago sativa L.) belongs to perennial cross-pollinated plants, the genetic composition of the group is complex and diverse, the genotype is in a heterozygous state for a long time, and the plants are incompatible by self-crossing, so the alfalfa mainly adopts methods of mixed selection, comprehensive variety breeding, recurrent selection and the like to breed new varieties. However, the method at least needs 6-7 years to breed an excellent group, homozygous materials are extremely difficult to obtain, the breeding period is long, the breeding difficulty is high, the efficiency is low, haploid breeding is one of ideal choices of alfalfa breeding ways, the materials with completely homozygous genotypes can be bred only through two generations, the breeding process is simplified, and the breeding efficiency is improved.
At present, the culture technology of plant free microspores becomes one of the most important means for obtaining haploid plants. Research on microspore culture technology is carried out on more than 250 species, the embryogenic rate of alfalfa cultured by adopting free microspores is low, and no report on obtaining haploid plants exists. Therefore, the method has an urgent need to improve the embryogenic rate of the alfalfa microspores by optimizing factors influencing the embryogenic rate of the plant microspores, so as to obtain haploid plants, and has important theoretical significance and practical value for accelerating the application of the microspore culture technology in alfalfa breeding.
In the alfalfa dissociation microspore culture technology, a mixed culture medium solution is prepared by an MS liquid culture medium and a B5 liquid culture medium according to the volume ratio of 1:1, microspores are dissociated in the mixed culture medium solution by slight squeezing of a pestle, filtrate is collected by filtering of a filter screen, centrifugation is carried out for 3 times, 3min is carried out each time, then the filtrate is suspended in a mixed culture medium consisting of half amount of the MS liquid culture medium and half amount of NLN liquid culture medium, and special centrifugal equipment is used in the step.
Disclosure of Invention
An object of the utility model is to provide a device for alfalfa haploid cultivates for centrifugation mixed culture medium solution.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a device for alfalfa haploid is cultivateed, includes motor, support, centrifuge tube, upper cover, rotation axis, rack, filter screen and closing cap, wherein:
