Abstract
The invention relates to a method for planting hot pepper, which comprises that using pepper as mother and father to be crossed; using selection method to plant a better parental generation self-cross system; using pepper as mother and using pimento as father to be crossed; using selection method to plant another better parental generation self-cross system; using said two self-cross systems as parents, using hybrid technique to plant the hot pepper. The inventive hot pepper has uniform size and beautiful appearance, while the price is 0.2-0.3yuan higher than other kinds and each unit field can generate 1500kg.
Description
Technical field
The invention belongs to the plant breeding technique field, the method for particularly a kind of high-quality capsicum variety seed selection.
Background technology
Capsicum is one of main vegetable crop of China, occupy consequence in vegetables industry.Capsicum produces the important component part that has become the many provinces and cities of China "three highs" agriculture, has become one of the pillar industry in many cities, county.
In China produced, the fruit properties according to capsicum was divided into capsicum types such as goat's horn green pepper, long red pepper, capsicum annum fasciculatum, line green pepper, pimento very early; According to purposes, capsicum can be divided into eats, processes two classes raw.
The capsicum quality comprises marketing quality, nutritional quality and flavor quality.Marketing quality mainly comprises the appearance character of fruit, and it has determined the commercial value of capsicum; Nutritional quality mainly comprises nutrient components such as vitamin, dry matter content, and flavor quality refers to capsaicin content etc., and nutritional quality and flavor quality have determined the thing of capsicum with being worth.
At present, eat raw in goat's horn green pepper and the long red pepper production in China, the nutritional quality and the flavor quality of used capsicum variety are better, and marketing quality is relatively poor, and it is little mainly to show as the big tail of carpocephalum, and is crooked, the fruit face is wrinkle, and fruit is flat, and this has had a strong impact on the commercial value of capsicum.
Summary of the invention
In order to overcome the deficiency that above-mentioned existing capsicum variety exists, the object of the present invention is to provide the method for a kind of high-quality capsicum variety seed selection, thereby select the high-quality capsicum variety, to satisfy the demand in market.
The marketing quality that high-quality capsicum variety of the present invention is meant fruit is good, concrete feature is: the fruit cylinder shape, long 16.0～26.0 centimetres of fruit, fruit top (head) portion rugosity is 2.5～10.0 centimetres, fruit is big or small end to end more consistent, concrete characteristics are: the fruit rugosity is 95～100% of a fruit top rugosity during 1/2 fruit length, the fruit rugosity is 90～100% of a fruit top rugosity during 4/5 fruit length, and the fruit afterbody is more blunt, and fruit is straight, fruit surface smooth is glossy.
The method of capsicum variety seed selection of the present invention is to be the parent with the high-quality selfing, utilizes the hybrid vigour technology to select the high-quality capsicum variety.
Purpose of the present invention is achieved through the following technical solutions: a kind of method of capsicum variety seed selection comprises the steps:
(1) select a high-quality parental inbred line by the systematic breeding method: little with the big tail of carpocephalum, crooked, fruit face is a female parent than wrinkle, the flat sharp green pepper material of fruit, size evenly end to end, the sharp green pepper material of straight, the fruit surface smooth of fruit, fruit cylinder shape is male parent with fruit, hybridize, obtain F
1Generation then is that recurrent parent is to this F with the male parent
1Backcross 1～2 time, obtain BC1～BC2 from generation to generation, then size evenly end to end, straight, the fruit surface smooth of fruit, fruit cylinder shape etc. are target with fruit, and its offspring is selected, and selects the plant that meets target to reserve seed for planting, and obtains seed; Plant these seeds, continue that size evenly end to end, straight, the fruit surface smooth of fruit, fruit cylinder shape etc. are that target is selected with fruit; Like this, through the systematic breeding of 3～4 generations, select a high-quality parental inbred line.
(2) select another high-quality parental inbred line by the systematic breeding method: little with the big tail of carpocephalum, crooked, fruit face is a female parent than wrinkle, the flat sharp green pepper material of fruit, size evenly end to end, the pimento material of straight, the fruit surface smooth of fruit, fruit cylinder shape is male parent with fruit, hybridize, obtain F
1Generation then is that recurrent parent is to this F with the male parent
1Backcross 1～2 time, obtain BC1～BC2 from generation to generation, then size evenly end to end, straight, the fruit surface smooth of fruit, fruit cylinder shape etc. are target with fruit, and its offspring is selected, and selects the plant that meets target to reserve seed for planting, and obtains seed; Plant these seeds, continue that size evenly end to end, straight, the fruit surface smooth of fruit, fruit cylinder shape etc. are that target is selected with fruit; Like this, through the systematic breeding of 3～4 generations, select another high-quality parental inbred line.
(3) utilize the hybrid vigour technology to select the high-quality capsicum variety: with above-mentioned two high-quality selfings is the parent, utilizes the hybrid vigour technology, hybridizes, and selects the high-quality capsicum variety.
The high-quality parental inbred line that selects in the described step (1) has following feature: the thin cylinder shape of fruit, long 16.0～30.0 centimetres of fruit, thick 2.0～4.0 centimetres of fruit top (head) portion, fruit is big or small end to end more consistent, and concrete characteristics are: the fruit rugosity was 90～100% of a fruit top rugosity when fruit rugosity was 95～100%, 4/5 a fruit length of fruit top rugosity during 1/2 fruit length, the fruit afterbody is more blunt, fruit is straight, and fruit surface smooth is glossy.
The high-quality parental inbred line that selects in the described step (2) has following feature: the thick cylinder shape of fruit, long 10.0～20.0 centimetres of fruit, thick 4.5～12.0 centimetres of fruit top (head) portion, fruit is big or small end to end more consistent, and concrete characteristics are: the fruit rugosity was 90～100% of a fruit top rugosity when fruit rugosity was 95～100%, 4/5 a fruit length of fruit top rugosity during 1/2 fruit length, the fruit afterbody is more blunt, fruit is straight, and fruit surface smooth is glossy.
The high-quality capsicum variety that selects in the described step (3) has following feature: the fruit cylinder shape, long 16.0～26.0 centimetres of fruit, fruit top (head) portion rugosity is 2.5～10.0 centimetres, fruit is big or small end to end more consistent, and concrete characteristics are: the fruit rugosity was 90～100% of a fruit top rugosity when fruit rugosity was 95～100%, 4/5 a fruit length of fruit top rugosity during 1/2 fruit length, the fruit afterbody is more blunt, fruit is straight, and fruit surface smooth is glossy.
The big tail of described carpocephalum is little, crooked, wrinkle, the flat sharp green pepper material of fruit comprise No. 2 capsicums of Lip river green pepper, U.S. Big Jim, the west of a river, Hunan long red pepper or Chifeng, Inner Mongol long red pepper to the fruit face.
Size evenly end to end, the sharp green pepper material of straight, the fruit surface smooth of fruit, fruit cylinder shape comprises red sharp green pepper of Korea S or Hunan smooth bark green pepper for described fruit.
Size evenly end to end, the pimento material of straight, the fruit surface smooth of fruit, fruit cylinder shape comprises eggplant door pimento or long pimento for described fruit.
The present invention compares with existing pepper breeding technology, has following advantage and beneficial effect:
1) high-quality capsicum variety of the present invention, its fruit is big or small end to end more consistent, aesthetic in appearance; And all there is a shortcoming that big tail is little, marketing quality is relatively poor in the fruit of existing capsicum variety.
2) plant the high-quality capsicum variety that the present invention selects, the fruit price is higher 0.2～0.3 yuan than other kind per kilograms; In 1500 kilograms every mu, the high-quality capsicum variety that plantation the present invention selects can be overcharged into 300～450 yuan for every mu.
