In-vitro oriented screening method of peanut high-oil body

Abstract

The invention relates to an in-vitro oriented screening method of a peanut high-oil body, which is capable of solving the problems that peanuts are lack of high-oil germplasm resources and high-yieldand high-oil peanut varieties are difficult to cultivate through conventional breeding. The high-oil body is screened through an in-vitro oriented screening way, a screening process is proceeded in aculture medium, a large amount of culture materials without resistance are eliminated, a large amount of resources and cost can be saved and reduced, mutagenic culture and oriented screening can be carried out all the year round, and the operation is convenient. New peanut high-oil germplasms can be created and screened, genetic basis of peanuts can be broadened, and the difficulty that breeding of the high-yield and high-oil new varieties is difficult to break through as the peanuts are lack of the high-oil germplasm resources can be overcome.

Description

technical field [0001] The invention belongs to the field of peanut breeding, in particular to a method for in vitro directional screening of peanut high oil bodies. Background technique [0002] Peanut is an important oil crop in my country and occupies an important position in the national economy. More than 50% of the peanuts produced in my country are used for oil extraction. Generally, the oil content of more than 50% is a high-oil variety or high-oil material. Every 1 percentage point increase in the oil content can increase the net profit by 7%. Therefore, new varieties of high-oil peanuts are cultivated. It has become one of the main breeding goals of the majority of breeders. However, there is a lack of high-oil variety resources in peanuts, and it is difficult to obtain high-oil offspring by cross-breeding. Therefore, the breeding of high-yield and high-oil varieties has always been a difficult problem to solve. The use of mutagenesis technology can cause gene mut...
