Description
Technical field
The present invention relates to a kind of crop in cruciferae cultivation mulch mini greenhouse and its applications, belong to plant breeding teclmiques neck
Domain.
Background technology
Baby cabbage (Baby Chinese cabbage), also known as miniature Chinese cabbage belong to Chinese cabbage (Brassica rapa
L.ssp.pekinensis a type), shape is consistent with common Chinese cabbage, but size just corresponds to the four of common Chinese cabbage
1/1 mono- to five, " the emulation miniature version " of similar common Chinese cabbage.Baby cabbage also known as Chinese cabbage originate from China,
Variety type is extremely abundant, is the special vegetable (Ke Guilan, 2010) of China.Currently, the great Bai of South Korea, Japan and other countries plantation
Dish is passed to by China earliest.For a long time, Chinese cabbage is always the backbone vegetables of China and East Asian countries, critical role
It is that other vegetables are difficult to compare with production area.
For a long time, due to being limited by kind and cultivation technique, Chinese cabbage is mainly as autumn vegetable cultivation.In recent years
Come, with the development that vegetable at protected field is cultivated, the situation that Chinese cabbage is also supplied from autumn production, half a year has gradually turned to more than a year
Stubble cultivation, year-round supply new frame.With the improvement of living standards, consumer proposes the appearance and flavor quality of baby cabbage
Requirements at the higher level.Due to the variation of family structure, demand of the market to big plant type Chinese cabbage is constantly reduced, and to spring sowing, summer sowing
It is increasingly urgent to the demand of the small-sized baby cabbage of autumn sowing.The demand of consumer and market to spring sowing baby cabbage is increasingly urgent to.At present
The sale for baby cabbage of sowing in spring in major, the medium and small wholesale vegetable market in the whole nation and supermarket.Spring baby cabbage available on the market
Kind is essentially from the imports kind such as South Korea, Japan, although these kind Late boltings are very strong, because of its heat resistance and viral diseases
Ability is poor.The existing spring sowing baby cabbage kind in China, although antiviral property is strong, Late bolting is poor, and shortening stem easily extends, leaf
The commodity of ball is poor.Therefore, selection and breeding are suitable for the extremely strong baby cabbage new varieties of Late bolting of China's spring sowing, are China vegetables
One of the vital task that dish industry faces.The core of spring baby cabbage breed breeding is the strong Late bolting breeding material of acquisition, and strong
The key that Late bolting breeding material obtains is high-throughput, Rapid identification bolting resistant property technology application.
The Late bolting of brassicaceous vegetable includes wanting basic nutrition growth type (such as wild cabbage), low temperature requirements type and long-day
Seek type three categories.Baby cabbage and the seed vernalization crop that turnip is basic nutrition growth phase, are typical low temperature requirements types, kind
After sub- vernalization, you can induction low temperature (Ke Guilan, 2010).Turnip is stringenter to low temperature requirements than baby cabbage, shows as extremely late bolting.
Hybridized with baby cabbage using turnip, the baby cabbage kind for being bred as anti-clubroot simultaneously, also the late bolting gene of turnip is transferred to
In baby cabbage, which can be applied to baby cabbage evening bolting breeding (Yui, 2003).Breeds of Chinese cabbage is slow May, and bolting is opened
Flower needs low temperature vernalization and longer sunshine condition.Hybridized with Chinese cabbage using baby cabbage, can isolate and only require in offspring
Long day, and the material insensitive to low temperature, which, which is applied to breeding, still prodigious distance (Yui, 1991,1992).
Bud differentiation is the key that baby cabbage bolting phenomenon occurs.The device of photoperiodic signal is experienced in baby cabbage bud differentiation
Official is blade, and the organ for receiving low temperature vernalization treatment signal is stem apex.Baby cabbage belongs to vernalization type, after seed maturity, radicle
Just there is the ability for experiencing low temperature after appearance.There are many reports for inducing baby cabbage vernalization optimum temperature.In general, doll
Dish seed vernalization temperature sensor is 0-13 DEG C.The requirement of different breeding material counterglow length is different with the requirement to temperature,
For some to day long sensitivity, some is then only temperature sensitive.Long-day can promote bolting and bloom.It is handed in the duration of day and temperature
In interaction, low temperature vernalization is the determinant of baby cabbage bud differentiation and bolting, in incomplete vernalization, the photoperiod amount of playing
Cumulative function.According to the cultivation practices of baby cabbage, baby cabbage bolting is acted on by low temperature vernalization, also receives the shadow of photoperiod
It rings.Above-mentioned principle is exactly that we establish the theory of the identification method of baby cabbage breeding material Late bolting in breeding cultivation production
Basis.
It is reported according to previous literature, Late bolting identification method has very much.Mero etc. (1984) is existed using 2-3 leaf tinkling of pieces of jade seedling
It is handled 6-7 weeks under 5 DEG C of cryogenic conditions, investigates squaring period or shortening stem length identifies Late bolting.Yu Yangjun etc. (1996) is utilized
Indirect indexes of the number of sheets as evaluation breeding material Late bolting when blooming.Cheng Fei etc. (1999) thinks that baby cabbage bolting is early
Evening and Floral initiation significant positive correlation can replace bolting sooner or later, in breeding time with Floral initiation
Interior progress Late bolting shape selection.The above research, the judgement to bolting use the discrimination method of bud differentiation morning and evening.So
And after bud differentiation, bolting process is also influenced by temperature and photoperiod, and the different kind of counterglow length requirement is compared, flower
Bud differentiation is more early, and to be not meant as bolting more early.2004, remaining sun person of outstanding talent etc. by 3 DEG C of germinating seed low temperature vernalization treatment 20 days, and
After be seeded in 20-22 DEG C of greenhouse, night fluorescent lamp light filling to 16 hours photoperiods, 108-144 μm of ol/ (m2 of light filling light intensity
s);Integrated survey buddings, bolting, situation of blooming, using bolting index as the morphological index of the late bolting of evaluation.Bolting index (%)
Algorithm be:(∑ series × strain number at different levels) × 100/ (9 × investigation total strain number).Bolting index evaluation cycle is about 45 days.On
The method for stating identification Late bolting has the advantages that respective, also there is respective limitation.These methods it is accurate whether, will also be by big
Field plants to examine, because they cannot cover all field low temperature and photoperiod integrated environment condition.
Since the country of China lacks the antiviral germplasm of baby cabbage evening bolting, strong Late bolting is imported to the parent of viral diseases
It is one of the important channel of late bolting breeding material selection and breeding in material.Using this approach, disease-resistant, late bolting is excellent obtaining for we
While benign shape, it can also increase the genetic diversity of breeding material.This approach includes hybridization, selfing or backcrossing and field
The processes such as Single-plant selection cannot carry out effectively evaluating identification using the method being documented to offspring's breeding material.
