| Abstract |
Besides capsaicin (CAP), capsiate (CAT) is now recognized as an important secondary metabolite of pepper (Capsicum spp.) for use as a health food, dietary supplement, and pharmaceutical. However, genetic resources for high levels of CAT are scarce worldwide. To develop new commercial pepper varieties with high levels of CAT, sources of variably are needed. This study was primarily conducted to evaluate the high CAT yield with or without CAP. Moreover, two DNA markers, which were associated with CAT and CAP were used to identify presence of these two secondary metabolites. The results indicated that accession KKU-P31146 contained the highest levels of CAT (505.3 µg/g DW) without Sum CAPs among 19 accessions tested. Although, KKU-P62268 pepper cultivar showed the highest Sum CATs (3794.1 µg/g DW), however, it contained lower levels of CAT than KKU-P31146. The dCAPS (p-AMT) molecular marker amplified DNA fragment of 269 bp, while a 1670 bp DNA fragment was not amplified by SCAR (Pun1) molecular marker. In addition, the genotypic data from the two known molecular markers were associated with CAT and Sum CAPs in all accessions tested. In particular, that association was clearly observed in KKU-P31146. The novel discovery here is that KKU-P31146 should be considered as a new source for breeding high CAT varieties, due to its high CAT and no CAP. An obvious association between genotypic and phenotypic trait related to CAT of KKU-P31146 indicated that the two known markers are useful for selection pepper varieties with the target trait. |
