Screening of High Capsaicin Rich and High-Yielding Hot Chilli Genotypes for Future Varietal Improvement

Bangladesh has a wealth of Capsicum species, which has led to the development of a large
number of hot chili landraces. Information on their genetic diversity, conservation status andpotential use is lacking. It is possible to introduce new varieties as there is
plenty of favorable environments for chili cultivation and high demand for hot chili. To
generate useful information toward the sustainable use, management and conservation of these
species, evaluation of diversity, sustainability and productivity of 50 chili genotypes from
home and abroad was carried out. Among them, Bangladesh Agricultural Research Institute (BARI)-released varieties were used as a reference. A one-factor experiment with three
replications following RCBD was conudcted. The results indicated that most of the genotypes demonstrated
satisfactory performance in yield. Few genotypes did not perform well, so all the genotypes
are needed to identify genetic variation and evaluate chemical components to detect a higher
level of sustainability.
