Dear Editor,Breeding a new wheat variety using traditional methods typically takes at least 8 to 10 years,and the breeding period can be dramatically shortened via a doubled haploid strategy,which can yield homozygote...
Telomeres cap ends of eukaryotic chromosomes prevent them from degradation and ensure genomic stability. Cdc13 is an essential telomere recruitment and maintenance protein. A temperature-sensitive point mutation in cd...

This article summarizes the research progress inthe breeding of maize haploids, including the production and identification of maize haploids, especially the methods to produce doubled haploids and the selection of ba...
Doubled haploid production via microspore culture is a technique known to accelerate crop breeding by shortening the breeding cycle through achieving homozygosity in one generation. Prior research observed that some e...
