ABSTRACT

The inheritance of capsaicin content in Capsicum chineuse Jacq. was studied from two crosses between the accessions 157 (pungent) x 261 (non pungent) and 220 (intermediate) x 261 (non pungent), and their six basic generations (P₁, P₂, F₁, F₂, BC₁, and BC₂). The character showed predominance of additive gene effects and the magnitudes of the narrow sense heritability indicate that the capsaicin content can be effectively changed by simple selection.

Keywords: Pungency; Capsicum chinense; Solanaceae.
