Whole-genome mapping reveals QTLs linked to key agronomic traits in bi-parental populations of field cress (Lepidium campestre).

ABSTRACT:

Background

Field cress, Lepidium campestre, is an oil and catch crop undergoing domestication for the Nordic region. In this study, the genetic bases of domestication-related traits of field cress are identified using three bi-parental F₂ mapping populations (MPs). The MPs were phenotyped for plant height (PH), inflorescence length (IL), pod density (PD), seed yield per plant (SYPP), seed dormancy (SD), and pod shattering measured with two different parameters (PSH1 and PSH2).

Results

The MPs were genotyped, with a targeted Genotyping-by-sequencing (GBS) method, SeqSNP, using 9,378 Single Nucleotide Polymorphisms (SNP) spanning across eight linkage groups (LGs) of field cress. There was wide phenotypic variation among the individuals for the agronomic traits measu
