Abstract
Hot pepper breeding program to increase the capsaicinoids content for pharmaceutical and food industry was carried out by crossing 3 varieties of Capsicum annuum [Jinda (JD), Maepong (BP) and Siam Hot (SH)] with 2 varieties of C. chinense [French Habanero (FH) and Mexican Habanero (MH)]. The mating design was a half-diallel (method 4 model 1). The crossing between these 2 species were successful with most of varieties except for BP x FH. A Randomized Complete Block Design with 14 treatments and 3 replications was employed for the progeny test in Khon Kaen Province during October 2005 - April 2006. Capsaicinoids content of progeny was recorded between 2,473-19,846 ppm/g whereas those for the parents were in the range of 2,257-11,917 ppm/g and the heterosis (MP) value of capsaicinoids was -2.30 % to 73.96 %.
