Method for preparing novel downy-mildew-resistant common head cabbage germplasm through protoplast asymmetric fusion

The invention discloses a method for creating a novel downy-mildew-resistant common head cabbage germplasm through a protoplast asymmetric fusion technology, solves the problems that a common head cabbage variety which has high resistance against downy mildew of cruciferae and is even immune is substantially not available in production at present and overcomes the defects of incompatible distant hybridization, large difficulty and high investment of a genetic engineering technology and the like. The method for preparing the novel downy-mildew-resistant common head cabbage germplasm through the protoplast asymmetric fusion is characterized in that: a brussels sprout carrying downy-mildew-resistant gene is used as a donor; protoplast of the donor is treated through UV (Ultraviolet) ray; the common head cabbage which is sensitive to the downy mildew and has other superior economical and agronomic characters is used as a receptor; and the novel downy-mildew-resistant common head cabbage germplasm is created through a protoplast asymmetric fusion method. In the method, the downy-mildew-resistant gene of the brussels sprout is transferred into a common head cabbage, so that a system for quickly breeding the novel disease-resistant germplasm is established by using a protoplast fusion technology, and a modern cabbage germplasm resource innovation and disease-resistant breeding high-efficiency technical platform is established.

Method for indoor quick amplification propagation of cruciferous vegetable lepidoptera pest parasitic wasps

The invention relates to a method for indoor quick amplification propagation of cruciferous vegetable lepidoptera pest parasitic wasps. The method includes the following steps: (1) acquiring parasiticwasp cocoons from a field; (2) performing verification on parasitic wasps for use after the parasitic wasps are hatched out from the acquired parasitic wasp cocoons; (3) planting radish seedlings inplanting pots in the condition of plant growth light sources; (4) performing indoor propagation on Plutella xylostella by using a suspension method; (5) allowing the acquired parasitic wasps from thestep (2) to perform mating; (6) selecting and putting the 2th-3th-age-group Plutella xylostella acquired from the step (4) in parasitic cups, and leading the parasitic wasps acquired from the step (5)to the parasitic cups to perform parasitism; (7) collecting parasitic wasp cocoons acquired from the parasitic cups, and cleaning the parasitic cups; and (8) repeating the above steps (2)-(7), and performing successive propagation on the Plutella xylostella and the parasitic wasps. The method is easy to operate, is efficient and convenient, is low in cost, can achieve indoor quick amplification propagation of the cruciferous vegetable lepidoptera pest parasitic wasps, and has a wide application prospect.

Method for acquiring novel species of brassicaceous vegetables and application method of novel specie of brassicaceous vegetables

The invention discloses a method for acquiring novel species of brassicaceous vegetables and an application method of the novel species of the brassicaceous vegetables. According to the method, free microspore culture is carried out between hybrid seeds of the brassicaceous vegetables of 'celery cabbage species*small cabbage species' or 'small cabbage species*variants' to obtain regenerated plants so as to create the novel species. The method is applied to breeding and comprises the main steps of carrying out vegetable hybridization on 'celery cabbage species*'small cabbage species' and 'small cabbage species*variants', inducing embryoid by virtue of the free microspore culture, acquiring the regenerated plants through the germination of embryoid, carrying out ploidy determination on the regenerated plants acquired through the culturing of the microspore culture, reserving seeds of double haploid and high haploid, carrying out morphological identification and nutritive index identification on descendants of the planted regenerated plants, and preparing cross composition. The method has the advantages of short period and high efficiency, provides materials for the efficient breeding of Chinese cabbage vegetables and has a wide application prospect.

Method for improving hybrid seed production yield of cabbages in facility

The invention relates to a method for improving the hybrid seed production yield of cabbages in facility, and belongs to the technical field of vegetable farming. The method includes the steps of seeding and seedling raising, land preparation and bedding, field planting of parent materials, bolting, bee depositing for fertilization, harvesting and the like. According to the method, seed productionof hybrid seeds of the cabbages in the facility is adopted, exotic other-cabbage pollen is effectively avoided, and the purity of the hybrid seeds is ensured; in the facility, black mulching film islaid, the growth of weeds can be effectively inhibited, the method also plays the roles of cooling and moisturizing the ground, and in this way, farm operation such as weeding and watering during beepollination can be reduced as far as possible; bees and mason bees are adopted to conduct matched pollination, and the mason bees are used for solving the problem that in a facility greenhouse, illumination is deficient, the temperature is high, the activity space is small, and bee pollination is deficient; the method not only can improve the yield of hybrid seed production, but also is low in cost, and reference is provided for facility seed production of other cruciferous crops.
