Diversity among lineages and relative importance of longevity traits in potted ornamental peppers

The chilli peppers an important vegetable crop in Brazil. Although there are little studies with the capsicum species. The aim of this work was to evaluate the pot life longevity of chilli lineages and their variability. The experimental design was performed in an entirely random design with three replicates and six treatments (lineages: 76, 82, 72, 132, 83 and 134). After the fructification and fruit maturation the plants were submitted to simulated transport conditions and later transferred to room temperature. The pot aging ability was daily evaluated. The traits observed were number of dropped leaves, number of yellow leaves, number of dry leaves, number of dropped fruits and longevity. The data were submitted to Analysis of variance and the means are separated by Duncan’s test (p≤0.05). The genetic variability was done by Mahalanobis distance with grouping by Tocher’s method. The relative importance of traits to variability was done by SINGH’s method. The lineage 132 presented major number of leaves dropped and the lineages 83 and 72 the minor values for this trait. The major numbers of fruit dropped was presented by lineage 82. The lineages that had survived for longer were 82, 132, 83 and 134. The Tocher’s method formed two groups: the first one with lineages 132, 143 and 75; and the second one with 82, 72 and 83. The SINGH’s method pointed out the variable number of yellow leaves (2%) and the trait that most contribute to diversity was the number of dropped leaves (43%).
