Description
Technical field
The invention belongs to crop breeding technical fields, and in particular to a kind of high yield and resistance to close high yield, precocity, resistance
The selection of good maize seed.
Background technique
Corn belongs to grain, economy and feeding dual-purpose crop, and trans-utilization range is wide, and popularizing planting area is big, has development well
And application prospect.But the main problem for influencing corn development in production at present is low output, and it is big that difference is showed between the time
And it is unstable, lack the corn excellent variety of good stress resistance and precocity.This problem is solved, is only examined from the angle of heredity
Consider, cultivates high yield, precocity, high-quality, good stress resistance superior corn kind using heterosis, hybrid vigor.
Chinese patent application publication No. CN103535269A discloses a kind of high-quality, how anti-, high with corn inbred line new product
The breeding method of system is selfed specifically by corn strain Swan (late) C4 by preferred strain, educate high-quality, high yield, resist more,
Height matches corn inbred line new lines osmanthus 1,000,000.Osmanthus 1,000,000 for educating of the present invention have accumulated it is high-quality, more it is anti-, high match etc. it is excellent
Benign shape Yu Yiti, but the maturity period of maize seed of the invention is later, High planting is poor, and high yield ability needs to be further improved.
Summary of the invention
The present invention provides the maize seed space jade 338 of a kind of high yield, precocity, good stress resistance in view of the drawbacks of the prior art
Selection, the corn hybrid seed space jade 338 have the characteristics that high yield, precocity, good stress resistance compared to existing corn variety.
Maternal SX3288: strain plant type is compact, plant height 180cm, fringe position 70cm, 18~20 leaves of complete stool.Tassel branch 2-4
It is a, anther yellow, sterile lemma yellow.Fringe thick 4.1cm, spike length 15cm, tassel row number 16-18 row, row grain number 46,100-grain weight 37.1g.
Fruit ear cartridge type shape, cob is red, half horse grain shape of seed.
Male parent SX5176: seedling leaf sheath purple, 165 centimetres of plant height, 50 centimetres of fringe position, plant type is compact, and the number of blade 19, leaf
Color is light green, and Tassel-Branch 5-7, glume color cyan, anther is red, filigree color light red.18 centimetres of spike length, tassel row number 12-
14 rows, cob are red.Seed coat color yellow, half dent of grain shape.
Corn hybrid seed space jade 338 of the present invention has the feature that
The combination seedling growth is strong, and seedling leaf sheath is lilac, and blade is light green color, and plant type is compact, and tassel branch is suitable
In, filigree is light red, plant height 265cm, fringe position 100cm.Fruit ear is tubular, and spike length is averaged 27cm, the thick 4.5cm of fringe.Seed is
Huang Li, seed-producing rate 90%, half dent type, red axis, robustness is good, highly resistance northern and southern leaf blight, disease-resistanting leaf spot, stem rot, straw staygreen,
Lodging resistance, insect resistace is good, and summer sowing breeding time is 103 days or so.
Compared with prior art, the present invention has at least the following advantages:
1) the resulting high yield of the present invention, resistance to close, precocious, good stress resistance maize seed seedling growth is strong, plant type is compact, male
Branch of the ear of grain is moderate, resistance to close, precocious, highly resistance northern and southern leaf blight, and disease-resistanting leaf spot, stem rot, straw staygreen, lodging resistance, insect resistace is good, the summer
Broadcasting breeding time is 103 days or so.
2) the resulting high yield of the present invention, resistance to close, precocious, good stress resistance maize seed precocity, seed-producing rate are up to 90%, compare
Apparent effect of increasing production, the corn of harvest are all had in existing maize seed (such as first jade 335, Zheng Dan 958, capital section 968 etc.)
High yield, niblet robustness are good.
Detailed description of the invention
Fig. 1 be high yield of the present invention, precocity, good stress resistance maize seed space jade 338 breeding flow chart.
Specific embodiment
Embodiment 1
Shown in referring to Fig.1, a kind of high yield, precocity, good stress resistance maize seed space jade 338 selection, including it is following
Step:
1) pioneer cenospecies X1132A (have a try and tested with seed from the provinces and regions of Shandong in 2004) is chosen, the pioneer is miscellaneous
It hands over kind of X1132A to mix powder selfing breeding in Hainan, pioneer cenospecies X1132A is selfed to obtain pioneer's cenospecies X1132AS1 generation
(lower abbreviation pioneer cenospecies X1132AS1 generation), by pioneer cenospecies X1132AS1 generation respectively Jinan and Hainan according to
4000 plants/acre are planted and are carried out jumpbogroup body, high density selection, select fine individual plant, latter year is to fine individual plant selfing two
In generation, simultaneously selects elite plant strain, then the elite plant strain chosen to above-mentioned latter year in latter year was selfed for two generations and continues selection accordingly
Elite plant strain, circuit sequentially, it is female that pioneer cenospecies X1132AS1 generation obtains stability series SX3288 after 6 selfings
This.
2) it chooses corn basis germline Shen 137 (deriving from Shandong Province's Zhaoyuan County institute of agricultural sciences) and recruits 835 (to derive from Shandong
The province Zhaoyuan County institute of agricultural sciences), hybridize to obtain Shen 137 × trick 835F1 generation in Jinan Changqing area, by Shen 137 × trick 835F1 generation
Powder is mixed in Hainan to be selfed to obtain Shen 137 × trick 835S1 generation, and 137 × trick of Shen 835S1 generation is selfed again in Hainan and obtains Shen
137 × 835S2 generation is recruited, by Shen 137, × recruit the plantation of 835S1 generation in Jinan Changqing area, by the Shen 137 × recruits 835S2
Generation plantation is later annual respectively to Shen 137 × trick 835S1 generation and Shen 137 × trick 835S2 generation selfing two in Hainan Region
In generation, Shen 137 × trick 835S1 generation and Shen 137 × trick 835S2 generation, after 6 selfings, pass through the jade planted to two places respectively
Disease resistance, lodging resistance and the comprehensive agronomy character of rice are selected, and stability series 8376 are obtained；
3) draw by stability series 8376 obtained in step 2) and outside is 5003 (from academy of agricultural sciences, Shenyang City) in Hainan
Crossbreeding obtains 8376 × 5003F1 generation, is selfed 8376 × 5003F1 generation to obtain 8376 × 5003S1 generation in Hainan,
In 8376 × 5003S1 generation, is selfed again in Hainan and obtains 8376 × 5003S2 generation, by 8376 × 5003S1 generation plantation
In Jinan Area, by 8376 × 5003S2 generation plantation in Hainan Region, choose the elite plant strain in 8376 × 5003S1 generation into
Row selfing 8 times, the elite plant strain for choosing 8376 × 5003S2 generation carries out selfing and top-cross respectively, each to carry out 8 times, chooses respectively
The elite plant strain of two places simultaneously selects disease resistance, lodging resistance and comprehensive agronomy character, obtains that economical character is good, coordinate force
Good stability series SX5176 male parent, and the performance of the stability series SX5176 male parent is measured.Described be measured is exactly to pass through
Multiple selfing means detect the economical character and coordinate force of the stability series SX5176 male parent.
4) by the stability series SX5176 male parent in stability series SX3288 female parent obtained in step 1) and step 3) in sea
Southern crossbreeding obtains the maize seed space jade 338 of high yield, precocity, good stress resistance.
The beautiful 338 breeding hybridized processes of the space are as follows:
