Annual progress on new gene characterization and novel technology development for wheat genetic improvement in 2023
In the past year,dramatic progress on wheat genetic improvement was achieved,including the exploring of new genes related to high yield,disease resistance,and drought and low temperature tolerance,the development of new germplasms with ideal disease resistance and promising yield and good quality potential,the creating of EMS-induced mutants in a large scale,the improvement of prime editing technology used in wheat and haploid induction system by wheat edited mutant,and the enrichment of wheat genome sequencing data on coverage and polymorphism.In future studies,these genes,materials,technologies,and genome sequencing information should be better used in wheat breeding for fully playing their roles.Particularly,multiple available genes or traits can be pyramided by crossing or advanced techniques to develop ideal wheat varieties which have high yield,multiple resistances,and satisfying quality.Additionally,more researches on aphid resistance,high temperature tolerance,and high photosynthetic efficiency are necessary in this crop for reducing yield loss in wheat production.
