ABSTRACT
Background:
Cultivated peanut (Arachis hypogaea L.) is a major oilseed crop worldwide. Fatty acid composition of peanut oil may affect the flavor and shelf life of the resulting food products. Oleic acid and linoleic acid are the major fatty acids of peanut oil. The conversion from oleic acid to linoleic acid is controlled by theΔ12 fatty acid desaturase (FAD) encoded byAhFAD2AandAhFAD2B, two homoeologous genes from A and B subgenomes, respectively. One nucleotide substitution (GCâAT) ofAhFAD2Aand an "A" insertion ofAhFAD2Bresulted in high-oleic acid phenotype. Detection ofAhFAD2mutation had been achieved by cleaved amplified polymorphic sequence (CAPS), real-time polymerase chain reaction (qRT-PCR) and allele-specific PCR (AS-PCR). However, a low cost, high throughput and high specific method is still required to detectAhFAD2genotype of large number of seeds. Kompetitive allele specific PCR (KASP) can detect both alleles in a single reaction. The aim of this work is to develop KASP for detectionAhFAD2genotype of large number of breeding materials.Results:
Here, we developed a KASP method to detect the genotypes of progenies between high oleic acid peanut and common peanut. Validation was carried out by CAPS analysis. The results from KASP assay and CAPS analysis were consistent. The genotype of 18 out of 179 BC4F2seeds was aabb.Conclusions:
Due to high accuracy, time saving, high throughput feature and low cost, KASP is more suitable fordeterminingAhFAD2genotype than other methods.
