| ABSTRACT The objective of this study was to evaluate stigma receptivity and anther dehiscence in three floral development stages in F3 population of ornamental pepper (Capsicum annuum). A total of 162 plants (81 of purple corolla and 81 of white corolla) were used in this study. To analyze the stigma receptivity and anther dehiscence, three floral stages were analyzed: bud, pre-anthesis, and open flower. For each stage, 33 flowers of each phenotypic class were collected. The receptivity of the stigma was detected by dripping hydrogen peroxide solution (3%). For the evaluation of the level of receptivity, scores of 0 to 3 were assigned, varying according to the bubbles percentage found on the stigmatic surface. Scores of 1 to 5 were assigned for the... |

| ABSTRACT Pepper plants of the genus Capsicum are widely grown worldwide. The Capsicum annuum species shows ornamental potential; nevertheless, in the state of Piauí, there has been a lack of studies on its performance, related to quality traits needed to meet market demand. The aim of this study was to estimate the genetic parameters and associations between traits of ornamental interest in C. annuum in order to indicate, by simultaneous selection of traits, accessions to start an ornamental pepper breeding program in Piauí. We evaluated 16 accessions of C. annuum under plastic house conditions at Universidade Federal do Piauí. Number of days to flowering, number of days to fruit maturation, plant height, number of fruits per plant, fruit persistence,... |
