Breeding method for once measuring quality of peanuts selected by multiple indexes

Abstract

The invention relates to a crop quality analysis method, in particular to a rapid quantitative method applicable to breeding for quality of peanuts with multiple indexes. The breeding method for once measuring the quality of peanuts selected by multiple indexes is characterized by comprising the steps as follows: firstly, matching high-quality parent with hybridized combination and selecting true hybrid; or mutagenizing seeds; and secondly, carrying out quality selection on the seeds, wherein the selection of true hybrid is based on sequencing or utilizes a near infrared quantitative analysis model of the main quality trait of naturally air-dried single peanut and the quality selection method of the seeds relies on natural air-drying of a large sample and/or the near infrared quantitative analysis model of the main quality trait of the naturally air-dried single peanut. By the technology, high oleic acid and high oil peanut materials are identified already. Besides the selection of early generation and late generation in the breeding for quality of peanuts, the technology can be used for evaluating the quality of hybridization operation, optimizing the mutagenesis technology and controlling the quality in seed production.

Description

technical field [0001] The invention relates to a crop quality analysis method, in particular to a rapid quantitative method suitable for multiple quality indexes of peanut quality breeding. Background technique [0002] The quality improvement of peanuts should be based on the priorities of industrialization needs. From the perspective of meeting the domestic demand for edible oils and fats, high-oil breeding should be placed in a very prominent position. With the development of the economy, the proportion of edible peanuts will increase year by year, and attention should be paid to improving the quality of edible peanuts. Improving the protein and reducing the oil content of edible peanuts can be partially achieved through processing techniques, but for peanuts consumed in the form of roasted fruit and cooking, this goal needs to be achieved through breeding methods. Increase the oleic acid content of peanuts in an all-round way, especially pay attention to increasing th...

Problems solved by technology

From the perspective of the needs of peanut quality breeding in northern production areas, these models generally have one or another deficiency, such as: incomplete indicators, insufficient representativeness of modeling samples (not including large and small grain samples, large gaps in content), need The special sample pretreatment process (drying at 60-65° for 6h) is difficult to be used for early generation selection, or it was developed with equipment from different manufacturers, and cannot "realize one-time measurement, multi-component quantification"
