AI Technical Summary
In the current process of constructing wheat recombinant inbred line populations, parental selection is easily affected by the environment, the authenticity of hybridization is difficult to identify, the population purification cycle is long, and the efficiency is low.
SSR markers were used to screen parental combinations, and photothermal regulation technology was combined to optimize the hybridization verification and generation progression process. 21 pairs of SSR primers were used to detect genomic differential sites to achieve rapid and accurate hybridization and population purification.
It shortens the population construction cycle, improves genetic stability, and enables the efficient construction of wheat recombinant inbred line populations. It is suitable for genetic map construction, quantitative trait locus localization, gene cloning, and molecular design breeding.
