Abstract
The invention discloses a kind of breeding method of higher fatty acid high-yield peanut, comprise the following steps：Selection Luo spends No. 6 to make the maternal, Weihe River and spends No. 8 to do male parent collocation cross combination, obtain first F1 generation；Doing the maternal, Weihe River with first F1 generation spends No. 8 to do male parent backcrossing for the first time, obtains second F1 generation；Doing the maternal, Weihe River with second F1 generation spends No. 8 to do second of backcrossing of male parent, obtains the 3rd F1 generation；The continuous selfing of 3rd F1 generation obtains F2, F3, F4, F5 generation, since F3 generations, per in generation, all selects high-fat individual plant to carry out self propagated, strain is proceeded by from F6 generations to compare, elite plant strain is selected to enter identification garden, then the yield and quality qualification test of 2 years multiple spots is carried out, the new peanut variety of higher fatty acid high yield is obtained.The present invention have breeding method is simple, blindness is small, efficiency high the characteristics of.The good new peanut variety of higher fatty acid high yield, Comprehensive Traits or strain can be cultivated, with good economic benefit and social benefit.
Description
Technical field
The invention belongs to peanut breeding technical field, and in particular to a kind of breeding method of higher fatty acid high-yield peanut.
Background technology
Peanut, is one of main oil crops of China, according to statistics, and China has the peanut of more than half to be used for extracting oil.With
When preceding, oil pressing mill is just as the procurement price of peanut, but in recent years, the price of purchase peanut has but pulled open shelves
Secondary, the price difference between peanut varieties is also increasing, and its reason is that they can calculate the oil content of peanut, oil-containing now
Amount is per high one percentage point, and enterprise is not in the case where increasing any input, and benefit can increase 6%-8%.So, oil pressing mill works as
So like purchasing the high peanut of oil content.Oil content described in oil pressing mill, with the specific term in scientific research crude fat content,
The most peanut varieties of China, crude fat content is 45% or so, and peanut of the crude fat content more than 50% is just high oil bloom
It is raw, but for a long time, China and the straight grip of peanut breeding person one raising peanut yield target the most in the world, to higher fatty acid
Quality breeding is seldom paid attention to, and higher fatty acid high-yield peanut variety is seldom.
The content of the invention
The purpose of the present invention is that there is provided a kind of breeding side of higher fatty acid high-yield peanut for above-mentioned the deficiencies in the prior art
Method.
The technical scheme is that realize in the following manner：
A kind of breeding method of higher fatty acid high-yield peanut, comprises the following steps：Selection Luo spends No. 6 work female parents, the Weihe River to spend No. 8 to do
Male parent collocation cross combination, obtains first F1 generation；Doing the maternal, Weihe River with first F1 generation spends No. 8 to do male parent backcrossing for the first time, obtains
Obtain second F1 generation；Doing the maternal, Weihe River with second F1 generation spends No. 8 to do second of backcrossing of male parent, obtains the 3rd F1 generation；3rd
The continuous selfing of F1 generation obtains F2, F3, F4, F5 generation, since F3 generations, per generation all select high-fat individual plant to carry out self propagated,
While high yield individual plant is selected, higher fatty acid not damaged selection is carried out using near-infrared diffusing reflection spectrum not damaged selection technique,
High-fat individual plant is subjected to selfing, selection of future generation is carried out；Strain is proceeded by from F6 generations to compare, selection elite plant strain enters
Garden is identified, the yield and quality qualification test of 2 years multiple spots is then carried out, the new peanut variety of higher fatty acid high yield is obtained.
The present invention has advantages below：
The breeding method for the higher fatty acid high-yield peanut that the present invention is provided, with breeding method is simple, blindness is small, efficiency high
The characteristics of.The good new peanut variety of higher fatty acid high yield, Comprehensive Traits or strain can be cultivated, with good economic benefit and
Social benefit.
Embodiment
Technical scheme is further illustrated below by specific embodiment.
A kind of breeding method of higher fatty acid high-yield peanut, comprises the following steps：Selection Luo spends No. 6 work female parents, the Weihe River to spend No. 8 to do
Male parent collocation cross combination, obtains first F1 generation, wherein：Luo spends No. 6, per mu yield pod 290kg, crude fat content 49.8%；
Spend 346.66 kilograms of 8 average yield per mu pod, crude fat content 52.7% in the Weihe River；Doing the maternal, Weihe River with first F1 generation spends No. 8 to do male parent
It is returned for the first time, obtains second F1 generation；Doing the maternal, Weihe River with second F1 generation spends No. 8 to do second of backcrossing of male parent, obtains the 3rd
Individual F1 generation；The continuous selfing of 3rd F1 generation obtains F2, F3, F4, F5 generation, since F3 generations, per generation all select high-fat individual plant
Self propagated is carried out, while high yield individual plant is selected, high fat is carried out using near-infrared diffusing reflection spectrum not damaged selection technique
Fat not damaged is selected, and high-fat individual plant is carried out into selfing, carries out selection of future generation；Strain is proceeded by from F6 generations to compare, and is selected
Select elite plant strain and enter identification garden, then carry out the yield and quality qualification test of 2 years multiple spots, the peanut for obtaining higher fatty acid high yield is new
Kind Luo spends No. 9, and average yield per mu pod 383.9kg, crude fat content 59.64% belongs to higher fatty acid high-yield peanut new lines.
Above by the embodiment of embodiment form, the present invention is described in detail, but this should not be managed
Solve the embodiment that the above is only limitted to for above-mentioned subject area of the invention, it is all based on the above of the present invention it is achieved that
Technology belongs to the scope of the present invention.
