A Crop Virtual Breeding Method Based on Plant Function and Structure Model

Abstract

A crop virtual breeding method based on plant function and structure model. This method will combine the physiological and structural crop virtual growth model and quantitative genetic information to achieve the purpose of virtual breeding by simulating the growth and development process and reproduction process of the crop. The steps are: collecting physiological data, morphological data, and quantitative genetic data of the crop. Construct the original data set with the growth environment data; based on the original data, construct the crop function and structure model through the method of computer graphics and the principles of crop physiological ecology; construct the genetic module, including the quantitative genetic information, and establish the parameters from the quantitative genetic information to the relevant model connection; add the simulation of genetic operations such as crossover and recombination in the hybridization process, and realize the simulation of the crop reproduction process; through the selection and hybridization of individuals in the model, virtual breeding can be realized; the proposal of the present invention can use computer technology to realize crop breeding Virtual breeding, thus assisting and supporting traditional breeding processes.

Description

technical field [0001] The content of the present invention relates to the fields of plant physiology and ecology, plant visualization modeling and crop breeding. It is a method capable of simulating the process of crop breeding through a three-dimensional visualization model, which can be used to assist and support field crop breeding. Background technique [0002] Traditional breeding has a relatively complete breeding theory and technical system, and the development of new technologies, including biotechnology, gene technology, etc., can promote the achievements and development of crop breeding. At present, emerging assisted breeding methods include molecular marker assisted breeding, cell engineering breeding and genetic engineering breeding, etc. Combining molecular breeding, gene breeding and other technical means with conventional breeding methods can greatly promote the improvement of breeding level. However, other new technology breeding methods other than conventio...

AI Technical Summary

Problems solved by technology

However, other new technology breeding methods other than conventional breeding methods still have great limitations, including that research in this area requires a lot of technical accumulation, and the implementation also requires specific instruments and equipment support, which has caused a huge increase in research costs. increased, thereby decoupling from the actual breeding process during development

Moreover, even breeding experiments combined with new technologies require long-term field trials, especially when the target plant type is uncertain and lack of pertinence

In addition, due to the imperfect safety evaluation and identification mechanism, the safety of food crop varieties obtained by related new breeding methods has also been greatly questioned, which limits the development and promotion of these new technologies
