Problems solved by technology

However, the prediction of breeders depends on the accumulation of long-term practice experience. Different breeders have different experiences and different emphases. The genetic factors involved in the prediction may not be comprehensive, and some genetic factors with high yield potential may be missed. The combination

Abstract

The embodiment of the invention provides a whole genome prediction method and device based on RRBLUP. The method comprises the following steps: obtaining genotype data of a hybrid to be predicted; according to a pre-established RRBLUP prediction model and the genotype data of the hybrid seeds, predicting phenotype data of hybrid combination progenies to obtain a phenotype data prediction result; And in combination with breeding resources and scales, selecting candidate hybridized combinations with high yield potential according to phenotypic data prediction results. By utilizing the method provided by the invention, the genotype of the hybrid can be speculated according to the parent genotype, so that the phenotypic data of the hybrid can be predicted, and the hybrid combination with highyield potential can be recommended.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of breeding, and in particular to a method and device for genome-wide prediction based on RRBLUP. Background technique [0002] The main goal of crop breeding is to develop new varieties that perform better than existing varieties on the market. Hybrid breeding using heterosis can produce hybrids that perform better than their parents. For example, the promotion and application of hybrid rice and hybrid corn have increased food production and contributed to the guarantee of global food security. [0003] In the process of cross-breeding, it is necessary to obtain a large number of hybrids through cross-breeding, and conduct multiple rounds of multi-level screening in the field, and then carry out tests at multiple points for many years, and finally obtain new varieties that meet people's expectations as much as possible. The agronomic traits of the hybrid offspring of random paren...
