Abstract

Abstract:

In recent years, BSA-seq technology has been widely used in the mining of new genes related to agronomic traits. With the development of the first reference genome of pea, it is imperative to combine BSA-seq method with genome-wide sequencing for gene mapping. In this study, we used purple flower parent G0004562, white flower parent G0002930, and F₂ populations for preliminarily locate the target genes controlling flower color by BSA-seq technology, and a mapping region of 31.42 Mb was obtained. Then, the InDel molecular markers were designed to further narrow the mapping interval, and finally the target gene was located in the range of 0.99 Mb with 19 genes. Based on gene annotation, Psat6g060480.1 was considered as the candidate gene that controled the flower color. The results of this study verified the feasibility of gene mapping by BSA-seq technology in pea.

Key words: pea, BSA-seq, InDel, gene mapping
