PARDEY RODRIGUEZ, Catherine; GARCIA DAVILA, Mario Augusto  and  VALLEJO CABRERA, Franco Alirio. Agronomic evaluation of Capsicum accessions of the gene Bank of the National University of Colombia at Palmira's campus. Acta Agron. [online]. 2009, vol.58, n.1, pp.23-28. ISSN 0120-2812.

100 accessions from Capsicum gene Bank of the National University of Colombia at Palmira's campus, under field conditions of the experimental station at Candelaria, Cauca Valley were studied. In a design of incomplete blocks 10 x 10 with three repetitions, quantitative descriptions were evaluated. The characteristics were related with yield, capsaicin content and virus presence.The agronomic evaluation found that the differences among the accessions are explained for the capsaicin content, yield, characteristics associated and fruits characteristics associated. Inverse correlation among the capsaicin content with production, quantity of fruits for plant with weight was found. The dispersion of the accessions in the Cartesian axis placed the commercial varieties: Cayenne, Tabasco and Habanero in terms of yield, weight and number of fruits in unfavorable positions with regard to the general averages. The same was observed for the stability of the characteristics above mentioned. There were four introductions with high capsaicin contents that overcome Tabasco. Four virus types affecting plants were evaluated: potyvirus, geminivirus, cucumovirus and virus of the mosaic of the tobacco (TMV). The viruses were acting together; the potyvirus with the cucumovirus and TMV and geminivirus with TMV.

Keywords : Pepper; chili; yield; capsaicin; virus.
