Abstract

The invention provides a rapid multi-target property polymerization breeding method for rape, belonging to a plant breeding method, and comprising the following steps of: selecting excellent breeding target properties requiring to be polymerized, preparing single-cross combinations at room temperature in winter locally, preparing multi-parent complicated cross combinations in summer at different places, and assembling and polymerizing the multiple parents with excellent target properties based on the breeding requirements; performing microspore seedling cultivation on the complex filial generation for which multi-target property breeding restructuring polymerization is already realized, constructing a dihaploid (DH) breeding group, and realizing rapid fixation and homozygosis of the target genotypes of the generation of the multi-target property polymerization; and performing effective field and indoor identification and screening on the target genotypes of the generation for which the multi-target property polymerization is realized based on the property characteristics, performing molecular marker assistant selection on important target properties, and breeding new materials conforming to the breeding targets.

Description

technical field [0001] The invention relates to rapid aggregation breeding of multi-objective traits of rapeseed, which belongs to plant breeding methods, and specifically relates to breeding methods such as off-site assembly and aggregation of multi-objective traits, rapid fixation and homozygosity of target genotypes, and effective identification and screening of aggregation traits. . Background technique [0002] Rapeseed is an important oil crop in my country, with an annual planting area of ​​about 100 million mu, a total output of more than 11 million tons, a production of more than 4.4 million tons of rapeseed oil, and more than 6 million tons of high-quality protein cakes. The planting area and total output rank first in the world first place. In the past two decades, through the vigorous promotion of new high-yield and double-low rapeseed varieties and their high-efficiency cultivation techniques, the yield of rapeseed in my country has increased significantly, the ...
