Crop virtual breeding method based on plant function and structure model

Abstract

A crop virtual breeding method based on a plant function and structure model. The method combines a physiological and structural crop virtual growth model and quantitative genetic information, fulfills the aim of carrying out virtual breeding by simulating the growth and development process and the propagation process of crops and comprises the steps of: acquiring physiological data, morphological data, quantitative genetic data and growth environment data of the crops to construct an original data set; based on original data, constructing the crop function and structure model by a computer graphics method and a crop ecology principle; constructing a genetic module which comprises the quantitative genetic information and establishing association from the quantitative genetic information to related model parameters; adding simulation on genetic operations of crossing, recombination and the like in the hybridization process and implementing simulation on the propagation process of the crops; and implementing virtual breeding by selection and hybridization on individuals in the model. By providing the crop virtual breeding method based on the plant function and structure model, virtual breeding of the crops can be implemented by a computer technology so as to provide assistance and support for a conventional breeding progress.

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
