Abstract
The invention discloses a parent propagation method for preventing cabbage parent mixing. The plants grown from axillary buds are taken from the plants, so that the 100% purity can be ensured, the characters of the plants are fully consistent with the characters of the original plants, and people do not need worry about the parent mixing. The method is simple and easily performed. The viability of the cabbage parent does not decline according to the method and the parent purity is ensured.
Description
Technical field
The present invention relates to a kind of parent breeding method preventing wild cabbage parent from mixing, belong to field of plant growing technology.
Background technology
Wild cabbage belongs to Cruciferae, Brassica genus, is biennial herb plant.Originate in Mediterranean Bei Yan, be the vegetables of training in worldwide year now, continent country of Europe, the United States is vegetables.Head cabbage is after 16th century imported China into, and due to its adaptability and strong stress resistance, stable yields, again storage tolerance, therefore very fast at China's cultivation development, every Annual planting area has reached 3,000,000 hm at present
2above, in vegetables year-round supply and the export trade, all critical role is occupied.
Because hybrid vigour, existing market uses cabbage seed to be substantially all half-blood, and growth potential, cold-resistant warm tolerance, disease resistance are all better than Parent.For the original seed of the wild cabbage production of hybrid seeds, all want amount reproduction every year, institute's breeding seed is used for greatly the next year production of hybrid seeds, and a small amount of seed is then for next year breeding stock.
Parent propagation is all use between strain to hand over, and for preventing parent from mixing, each parent is separately with grenadine isolation, and parent has awarded before powder changes another parent's pollination, needs to wash one's hands, washes instrument, changes one's clothes, mix to prevent the pollen of different parent to see in cause.But even so, still often can cause and mix on a small quantity, can not 100% guarantee purity.So, for the seed of Second Year parent propagation, be have in arms mistake to kill 1,000 after nursery field planting, the principle of can not be let slip, from seedling stage to bolting, must repeatedly impurity elimination be carried out.This producing method for seed, reduces the probability mixed to a certain extent, but but substantially increases working time and cost.
Summary of the invention
For current Problems existing, the invention provides a kind of parent breeding method preventing wild cabbage parent from mixing, effectively can improve breeding purity and save time.
To achieve these goals, the invention provides following technical scheme:
The parent breeding method preventing wild cabbage parent from mixing, comprises the following steps:
(1) begin sowing in good time according to local weather;
Etc. (2) seedling grow to 4 leaves wholeheartedly time field planting in booth or in isolation curtain;
(3) normal field management, until 2 ~ March of next year, cuts ball, stays bud, help bolting; When blooming, normal breeding is used for the parent of next year hybrid seeding;
Etc. (4) gather in time after seed maturity, during seed collection, leave a few strain depending on next year parent demand and do not remove, to plant Nitrogen Top Dressing once, grow up Deng axillalry bud on plant, cut by axillalry bud, the otch cut dips in root-inducing powder, is inserted in and waters permeable Medium Culture, be placed on shady and cool ventilation place, within about 10 days, send out roots, within about 20 days, field planting is in booth or isolation curtain, for next year parent propagation.
In the aforementioned parent breeding method preventing wild cabbage parent from mixing, the resident time described in step (2) is after planting about 1 month, and the spacing in the rows of field planting is 40 ~ 60cm, and line-spacing is 40 ~ 60cm.
In the aforementioned parent breeding method preventing wild cabbage parent from mixing, the ball that cuts described in step (3) cuts off whole for ball at the wild cabbage balling initial stage, stays siphonal lobe about 10.
In the aforementioned parent breeding method preventing wild cabbage parent from mixing, to stay bud to refer to cut after ball about 2 weeks described in step (3), plant is emerged sprouting 5 ~ 10, and stay 3 ~ 4, unnecessary cuts off at every turn; 3 ~ 4 remaining buds, can slowly grow up, and the beginning of spring in the coming year bolting bloom;
In the aforementioned parent breeding method preventing wild cabbage parent from mixing, the nitrogen fertilizer application amount described in step (4) is 5g/ strain, and described matrix is yellow sand.
In the aforementioned parent breeding method preventing wild cabbage parent from mixing, the time that the axillalry bud described in step (4) is cut is axillalry bud height about 10cm, about 8, blade.
In the aforementioned parent breeding method preventing wild cabbage parent from mixing, described gather refer to when brassica specie pod 2/3 turn yellow, plant grain flavescence brown time, gather in time, carry out by stages and in groups, make seed full maturity as far as possible, timely airing, threshing, to bask seeds, can preservation be put in storage when seed moisture content less than 7%.
In the aforementioned parent breeding method preventing wild cabbage parent from mixing, every strain clip axillalry bud about 50.
The invention has the beneficial effects as follows:
1, on plant get the plant that axillalry bud grows up to, can ensure that its purity is 100%, proterties and former plant completely the same, do not worry that parent mixes.
2, the method that the present invention is also prescinded by wild cabbage balling initial stage whole ball increases wild cabbage branch amount, number of blooming, while guarantee purity, also make wild cabbage hybrid seed yield increase.
3, the method is simple, wild cabbage parent vitality can be made not fail by the method, and ensures parental purity.
Embodiment
The experimental technique used in following embodiment if no special instructions, is conventional method.
Material used in following embodiment, reagent etc., if no special instructions, all can obtain from commercial channels.
The present invention includes following examples:
The parent breeding method preventing wild cabbage parent from mixing, comprises the following steps:
(1) seed and matrix are chosen
In this experiment, head cabbage varieties selects " winter liter " male parent, and matrix selects Switzerland " Pin Shi " vegetables dedicated substrate.
(2) sow
On August 20 (Transition In Jurong, Jiangsu), adopt cave dish seeding and seedling raising.
(3) field planting
Field planting in booth (September 10) during on seedling 4 leaf wholeheartedly, seeding row spacing 50 × 50cm.Normal rich water quality management.
(4) production of hybrid seeds parent propagation
Cut off whole for ball at the wild cabbage balling initial stage, stay siphonal lobe about 10; To cut after ball about 2 weeks, plant is emerged sprouting 5 ~ 10, and stay 3 ~ 4, unnecessary cuts off; 3 ~ 4 remaining buds, can slowly grow up, and the beginning of spring in the coming year bolting bloom; Normal crossbreeding parent used, seed maturity stays plant 10 strain after gathering, every strain Nitrogen Top Dressing 10g.
(5) parent propagation of next year breeding parent
Long sturdy axillalry bud scissors is cut by July 1 on the plant stayed, and dips in root-inducing powder, is inserted in and waters permeable Medium Culture, be placed on shady and cool ventilation place.After 20 days, will survive in plant field planting booth or isolation curtain.Normal management is until next year blooms, parent propagation.
(6) timely collecting:
When brassica specie pod 2/3 turn yellow, plant grain flavescence brown time, gather in time, carry out by stages and in groups, make seed full maturity as far as possible, timely airing, threshing, to bask seeds, can preservation be put in storage when seed moisture content less than 7%.
By the wild cabbage Parent material of seminal propagation, in order to ensure its purity, substantially all to remove about 30% the lower plant of phase knowledge and magnanimity (wild cabbage seedling stage is through insect bite, later stage cuts ball and cuts stem because of carelessness and all can affect its growth traits), and the parent adopting this method to breed does not worry its purity, the purity of 100% can be ensured.
