Embodiment 1

[0132] In this embodiment, the multi-objective optimization method for rice breeding provided by the present invention is illustrated by taking rice breeding in the second accumulated temperate zone of Heilongjiang Province as an example.

[0133] The method is specifically as follows:

[0134] Step 1: Construct the objective variable function of rice breeding in the second accumulated temperature zone of Heilongjiang Province, as follows:

[0135] (1) Design a multi-objective optimization variable system for rice breeding, which includes a target layer, a criterion layer and an index layer.

[0136] in:

[0137] The target layer is a multi-objective optimization variable design evaluation system for rice breeding in the second accumulated temperate zone of Heilongjiang Province.

[0138] The criterion layer is the high-yield and high-quality aspects of rice varieties.

[0139] The index layer includes the following 11 agronomic traits belonging to the high-yield aspect of ...

Abstract

The invention belongs to the field of crop breeding, and provides a rice breeding multi-objective optimization method, which comprises the steps of constructing a variable function, creating an objective optimization model, implementing optimization simulation solution and determining an optimization scheme. The method provided by the invention solves the defects that the thought in the current rice breeding target making process is too specific and poor in universality and applicability, and a conventional method is limited and low in unreliability . According to the method, blindness, ineffectiveness and unscientificity of breeding practice can be reduced, then the working efficiency, effect and efficiency of rice breeding practice are improved, the rice breeding target design theory andmethod are perfected, and beneficial references are provided for rice breeding target design and application in the future.

Description

technical field [0001] The invention belongs to the field of crop breeding, and particularly relates to a multi-objective optimization method for crop breeding, which is especially suitable for the multi-objective optimization of rice breeding. Background technique [0002] The breeding goal is the premise, basis and guide for carrying out the breeding practice, and its accuracy is directly related to the success or failure of the breeding work. As far as conventional sexual hybrid breeding of rice is concerned, the hybrid combinations currently prepared will not be approved until the next 10 years or so. application prospects. From 2015 to 2019, there were 69 main varieties of high-quality and high-efficiency rice varieties planting in Heilongjiang Province, of which 40 varieties were approved by Heilongjiang Province from 2013 to 2019, accounting for about 58% of all the main varieties, accounting for about 206 approved varieties in the province during this period. 19% o...
