Outline of Final Research Achievements

No.3341 from Bolivia is a non-pungent pepper cultivar. Our segregation analysis using pungent Habanero and non-pungent No.2 (p-amt), No.80 (p-amt), NMCA30036 (pun1) indicated that non-pungency of No.3341 is controlled by a novel single recessive gene, neither Pun1 nor p-AMT. In addition, Comt was also not related to non-pungency of No.3341. Moreover, from Rad-seq analysis of Habanero, No.3341 and F2 population, molecular maker linked to non-pungency of No.3341 was obtained.
