(2) must possess field resistance authenticate technology and artificial inoculation on seedling authenticate technology.
(3) possess the parent and preserve breeding and half-blood seeding technique.
4, the parent preserves propagation technique
(1) a kind commerial growing require is divided in parent's production field, will have 50m above or high seedling interrow crop and the above isolated area of 20m arranged between each kind.
(2) the hybrid strain production requirement is identical with distinct variety, carries out but must separate with seed farm, and also available large tracts of land bagging selfing way is produced the parent.
(3) the every use of crossbreed parents 3-5 generation, the kind of using its former half-blood and new system is compared, with the check parental performance, if the new production of hybrid seeds significantly becomes the inferior than former half-blood, its parents just can not continue to do breeding stock, should use the seed that meets the parental stock standard instead and produce original seed.
(4) to accomplish to cultivate strong sprout in the management of parent's production field, the optimum period field planting, soil fertility is even, and with also irrigation and drainage are convenient more than the solanaceous crops crop rotation 4-5, appropriate applied nitrogen is executed phosphorus potash fertilizer more, prevention and elimination of disease and pests in time.
Require when (5) gathering and collecting seed: the seed collecting fruit should reach full ripening stage, is gathered by the special messenger, the assorted strain fruit of strict rejecting, sick fruit and serious bad fruit etc.; Draw available aging processes such as submethod,, eliminate sick fruit and serious bad fruit etc. as with the cross-sectional fruit of fermentation rule; The seed of cleaning in sieve or the threshing ground dry, prevent being exposed to the sun with scald sub.Marked variety name, year, month, day is prepared warehouse-in.
(6) seed bank will be established the special messenger and is responsible for, and notes anti-ly mixing, protection against the tide, fire prevention, protection against rodents, insect protected etc., carries out the seed storage custodianship.And answer running check, guarantee seed quality.
5, cross-breeding technology
(1) seed farm requirement
Tomato is rained at hybrid seeding therebetween sometimes, and the farm work personnel are many, and for ease of operation with reduce disease, the sandy loam that is beneficial to draining is for well, and requires fertility level medium, and isolation distance is more than 50m.
(2) seeding and seedling raising:
The concrete seedtime of seedtime can be calculated according to different production of hybrid seeds area field planting periods and seedling age, about general seedling age 80-100d; Another factor that need consider is to regulate date of seeding, makes this flower synchronization of father and mother, and this this ripe similar temperament of combination father and mother requires one week of male parent seed early sowing.
Every mu of maternal sowing quantity 20-25g of seeding quantity is if sow the seeding quantity that then should suitably increase 20-50% again in cold bed.Generally speaking, every production 1kg hybrid seed needs maternal seed of 4-5g and 1g male parent seed approximately.
(3) parent's field planting
The open country field planting of field planting time can be carried out under the disconnected frost back minimum air temperature is stabilized in situation more than 5-8 ℃, and is in case seedling endures cold, or because of the late frost influence brings unnecessary trouble, certainly can not field planting slow excessively.General area, the middle and lower reach of Yangtze River is early April, and in 4 months along the line of the Longhai Railway, the last ten-days period, Liaodong Peninsula late April can shift to an earlier date 15-20d as if field planting to mid-May in protection facilities such as plastic tunnel.
The general every mu of field planting 3500-4000 of plantation density strain.
Originally the plant ratio of strain number of parents' planting proportion father and mother is 1 to compare 7-8.
(4) impurity elimination is checked in the parent field
Be to guarantee the purity of first-filial generation seed, the purity of will be by stages before hybridization work begins parents being planted strain endures strict scrutiny.Omit assorted strain for guaranteeing not have, this work should together be carried out by the several people.Before and after seedling stage and the field planting and before the artificial emasculation pollination, should pull out assorted strain and diseased plant, weak strain according to separately feature of parents, characteristic (whether strain shape, leaf, stem look, leaf look, growing way, branching habit and carpopodium have joint etc.).Also to pursue the strain inspection again before gathering pollen to male parent.
After hybridization finishes, also to check maternal plant repeatedly several times, flower that excision is not castrated and young flower bud and the fruit that does not make marks.Whether also must take on color, carpopodium according to fruit shape, fruit look, fruit when gathering has and has or not the mark of castrating pollination to pluck allocarpy on joint and the fruit.
(5) hybridization period
Hybridization is relevant with local weather conditions and planting type period.First inflorescence on the maternal plant is not hybridized, since the second inflorescence hybrid seeding.The hybrid seeding how at the end of May in the Yangtze river basin, northern area then was advisable in 6 months from 5 months, and the South China is many in production of hybrid seeds autumn and winter.
(6) plant is adjusted
Adopt two stalk trainings, respectively keep 2 inflorescence hybrid seedings on stem and two side shoots, such 6 inflorescences can be tied the allocarpy about 20, and other side shoot is extractd, and the fruit number of the production of hybrid seeds on each inflorescence is advisable with 3-4, should extract the bud of inflorescence end.After the production of hybrid seeds finishes, plant is cleared up, the flower bud of the production of hybrid seeds and newborn inflorescence will all not extractd, and repeat repeatedly, prevent to produce the selfing fruit.Note when plucking the top keeping 2 blades, burn in order to avoid exposure in sunshine fruit face causes on inflorescence top.
(7) strengthen the rich water quality management and the extermination of disease and insect pest
In the hybrid seeding later stage, temperature is more and more higher, often the multiple period of disease, therefore, at first will accomplish rationally to topdress, pour water on cultivation management, keeps the field health, finds diseased plant, in time removes.Simultaneously also want the combination with spraying medicament to prevent and treat.
