Abstract
Disclosed is a disc plant type high yield and high oleic acid peanut variety cultivation method. Disc plant type peanuts are characterized in that the plant type of the peanuts is in a crawl manner, the length of a first pair of lateral branches is within 40cm, the height of a plant is 25-35cm, the diameter of the plant is 65cm above, and the whole plant is 'disc'-shaped seemingly. The cultivation methods includes the steps of 1), cultivation of the disc plant type and high oleic acid single plants; 2), cultivation of the high yield and high oleic acid plants; 3), cultivation of the disc plant type high yield and high oleic acid peanut single plants; 4), cultivation of the disc plant type high yield and high oleic acid peanut varieties. The disc plant type high yield and high oleic acid peanut varieties have the advantages of small sowing quantity, high propagation coefficient, high yield, good quality, fitness for mechanical harvest, labor saving and the like, and are wide in application prospect.
Description
Technical field
The present invention relates to the breeding method of a kind of dish-type strain type high-yield, high gas oil ratio peanut varieties, belong to peanut breeding technical field.
Background technology
Peanut occupies critical role in agricultural planting industry, and as large agricultural product, peanut cultivation benefit is higher than general field crop, and especially for the peasant of poverty-stricken area, the income of plantation peanut is their main source of finance.The traditional planting habit of peanut is every mu of plantation 10000-12000 caves, and 2, every cave, generally, major peanut mu sowing quantity 25 kilograms of pods, small pod peanut 20 kilograms of pods, the seed expense of every mu is up to about 300 yuan.Peanut sowing quantity is large, and seed costs is high, limits the enthusiasm that peasant changes grow novel varieties, also constrains the breeding rate of peanut varieties.Therefore, cultivation can thin planting, and then reduces the dish-type peanut varieties of sowing quantity, the breeding rate of peanut varieties can be improved, to the cost that minimizing peasant changes new peanut variety, increase farmers' income, adjustment rural area plant structure is significant, is also conducive to the quick application of new work kind.
Peanut is as important oil crop, food crop and economic crops, and the requirement of consumer to peanut quality is more and more higher.Peanut main fatty acid is oleic acid and linoleic acid, and the two summation accounts for about 80% of all fatty acid.Oleic acid can reduce the content of blood total cholesterol and harmful low density cholesterol, but does not reduce the content of useful HDL-C; Oleic acid belongs to unit price unsaturated fatty acid, and non-oxidizability is strong, and product shelf time is long, and not easily oxidative rancidity goes bad.Therefore, high gas oil ratio quality merged and have higher economic worth in dish-type strain type high-yield peanut varieties, plantation dish-type strain type high-yield high gas oil ratio peanut varieties, will produce larger economic results in society.
Dish-type plant type peanut, refers to that peanut plant type is crawled, but within the first pair of side shoot length 40 centimetres, plant height 25-35 centimetre, plant diameter more than 65 centimetres whole plant seem " assorted cold dishes " shape.Not yet there is the report of the breeding method of dish-type strain type high-yield high gas oil ratio peanut varieties at present, also do not have the report that dish-type strain type high-yield high gas oil ratio peanut varieties is bred as.
Summary of the invention
Problem to be solved by this invention is just to provide a kind of breeding method of dish-type strain type high-yield high gas oil ratio peanut varieties, obtains the new peanut variety of dish-type plant type, high yield, high gas oil ratio.
Technical scheme of the present invention is achieved in that
(1) dish-type plant type, the cultivation of high gas oil ratio individual plant, high gas oil ratio peanut resource or kind is utilized to be female parent, spreading type peanut resource or kind are male parent, collocation hybrid combination obtains F1 generation, F2 generation is obtained by after the seed selfing of F1 generation, " a kind of method of nondestructively measuring main fatty acid content of peanut seeds " (patent of invention ZL200910136388.7) is adopted to filter out the seed in the F2 generation of high gas oil ratio, by the seed selfing in F2 generation, dish-type plant type is selected in its offspring, the plant of high gas oil ratio, from after in F4 generation, F5 generation, F6 is for selecting dish-type plant type in colony, the plant of high gas oil ratio, by F6 for dish-type plant type, each individual plant of the plant of high gas oil ratio is all planted, finally obtain the individual plant of stable dish-type plant type high gas oil ratio.Peanut plant type is crawled, but within the first pair of side shoot length 40 centimetres, plant height 25-35 centimetre, plant diameter more than 65 centimetres.
(2) high yield, the cultivation of high gas oil ratio individual plant, same high gas oil ratio peanut resource or kind is utilized to be female parent, high-yield peanut resource or kind are male parent, collocation hybrid combination obtains F1 generation, F2 generation is obtained by after the seed selfing of F1 generation, " a kind of method of nondestructively measuring main fatty acid content of peanut seeds " is adopted to filter out the seed in the F2 generation of high gas oil ratio, by the seed selfing in F2 generation, high yield is selected in its offspring, the plant of high gas oil ratio, in F4 generation after selfing, F5 generation, F6 selects high yield in colony, the plant of high gas oil ratio, by F6 for high yield, each individual plant of the plant of high gas oil ratio is all planted, finally obtain stable high yield, the individual plant of high gas oil ratio.
(3) cultivation of dish-type strain type high-yield high gas oil ratio peanut individual plant, the dish-type plant type high gas oil ratio individual plant obtained with first two steps is for female parent, high yield, high gas oil ratio individual plant is male parent, collocation hybrid combination obtains F1 generation, F2 generation is obtained by after the seed selfing of F1 generation, by the seed selfing in F2 generation, dish-type plant type is selected in its offspring, high yield, the plant of high gas oil ratio, in F4 generation after selfing, F5 generation, F6 is for selecting dish-type plant type in colony, high yield, the plant of high gas oil ratio, by F6 for dish-type plant type, high yield, each individual plant of the plant of high gas oil ratio is all planted, finally obtain stable dish-type plant type, high yield, the individual plant of high gas oil ratio, peanut plant type is crawled, within the first pair of side shoot length 40 centimetres, plant height 25-35 centimetre, plant diameter more than 65 centimetres.
(4) breed of variety, the individual plant Fast-propagation of the dish-type plant type the 3rd step obtained, high yield, high gas oil ratio, forms strain, becomes strain, carry out Yield compari@to each strain after the mixed receipts of each strain; The dish-type plant type of yield increased volume increase more than 10%, high yield, high gas oil ratio strain are carried out varietal yield test, are dish-type strain type high-yield high gas oil ratio kind than the kind of contrast volume increase 10%.
Good result of the present invention is: the breeding method of the dish-type strain type high-yield high gas oil ratio peanut varieties of invention, there is dish-type plant type and sowing quantity is few, breeding rate is high, output is high, quality better, be applicable to mechanized harvest, save the feature such as labour, have broad application prospects.Cultivate into dish-type strain type high-yield high gas oil ratio new peanut variety, will the application speed of new varieties be accelerated, improve the enthusiasm that peasant changes new peanut variety, reduce peanut kind of a cost, improve peanut interior quality, improve peanut per unit area yield, there are huge social benefit, economic benefit and ecological benefits.
