Peanut molecular breeding (PRJCA030360)

The RIL population constructed from the parents of large pod varieties and small pod germplasm resources was used as the experimental material. QTL-seq and RNA-seq techniques were used to mine the genetic loci and candidate genes of seed size-related traits, and KASP markers were developed for the identification of peanut germplasm resources. In order to obtain marker loci and candidate genes closely related to seed size, this study will provide a theoretical basis for genetic improvement of peanut seed size and breeding of new varieties.
