Problems solved by technology

[0003] At present, the analysis methods and technologies for the key issues of variety demand that restrict agricultural production are limited to the breeding experts of the research group combining their own practical experience to analyze breeding problems from the perspective of variety characteristics, and rarely consider the scientific and technological difficulties behind the problems, and Analyzing problems from the perspective of planting, processing, consumers and other main market benefit needs. At the same time, due to the different knowledge and ability of different breeding experts, the analysis methods or angles are not the same, and the conclusions drawn are also inconsistent, which can easily lead to the lack of systematic representation of the key issues in the analysis. gender, normative and practical

Embodiment 1

[0090] refer to figure 1 , the present embodiment provides a kind of breeding method, this method is based on the " Suijing 18 " rice variety breeding that key problem finds, solves, and the steps of this method are as follows:

[0091] (1) Constructing a problem database: using literature search, survey questionnaires, and comparative analysis methods to summarize problems and form a problem database for breed breeding needs.

[0092] Wherein, the specific steps of searching documents are as follows:

[0093] Select the China National Knowledge Network (www.cnki.net) literature search database.

[0094] Design conditions to retrieve paths, or relationships. Time: January 1, 1996 to December 31, 1999. Theme: rice in cold regions, rice in Heilongjiang. Keywords: problem, status quo, variety, breeding. Full text: Yield, quality, disease, chilling injury.

[0095] After analysis and summary, a total of 248 literature results were retrieved, including 226 Chinese literature ...

Abstract

The invention belongs to the field of crop breeding, and provides a crop breeding method. The crop breeding method provided by the invention comprises the following operation steps: constructing a problem database, creating a problem evaluation system, focusing on scientific research difficulties, and proposing a breeding cracking path. The crop breeding method provided by the invention is suitable for discovering and analyzing key problems of crop breeding, has the characteristics of systematicness, uniformity and high efficiency, and achieves modeled, objective, specific and operable analysis and solution of the key problems of breeding, so as to achieve the capability of targeted intervention and solution of the key problems of crop breeding; the method has the practical value characteristics that the contradiction between breeding target traits is solved, quantitative coordination is difficult to achieve, and the breeding effect is poor due to the fact that new crop variety breeding and production need to be disjointed.

Description

technical field [0001] The invention belongs to the field of crop breeding, in particular to a method for crop breeding. Background technique [0002] With the continuous development of the level of agricultural production and the continuous accumulation of genetic gains of excellent traits of crop varieties, the demand for the ability of scientific researchers to solve key problems that restrict agricultural production by innovating new varieties of excellent crops is increasing day by day. However, how breeders can effectively sort out and confirm these key issues from agricultural production practices, focus on scientific and technological research difficulties, and propose breeding solutions is one of the effective measures to improve the effect of crop breeding and help the sustainable development of modern agriculture. [0003] At present, the analysis methods and technologies for the key issues of variety demand that restrict agricultural production are limited to the...
