Abstract
The production of passion fruit is important in Brazil. In order to contribute to the development of the most promising cultivars of passion fruit, this study aimed to evaluate the agronomic performance of 32 genotypes of passion fruit in Federal District of Brazil, and to estimate genetic parameters for use in breeding programs. Thirty-two genotypes were used in a randomized block design, with eight plants per plot and four replications. The experiment was conducted in field. Twenty-eight harvests were performed, and the variables analyzed were: productivity estimated, total number of fruits per hectare, average fruit weight and these characteristics following classification of fruits in five categories. The genotypes that presented the highest total yield estimated were MAR20 # 23, AR 01 and PLANTA 7. For industrial purposes, genotypes MAR 20 # 21 and BRS Gigante Amarelo were superior. For fresh consumption, the genotypes with the best performance were PLANT 7, AR 01 and MSC. Total productivity estimated and total number of fruits per hectare in the first-class classification showed high values of heritability and CVg/CVe ratio. These results indicate a favorable condition for selection.

The genotype MAR20#23 had the highest productivity with 17,162 kg ha-1, followed by AR 01 (15,626 kg ha-1) and PLANTA 7 with 15,130 kg ha-1, differing statistically from the genotypes MAR20#29, PLANTA 5 and EC-3-0, which presented the lowest productivity, with 4,762, 4,625 and 4,097 kg ha-1, respectively (Table 2)
Summary
In the national fruit culture, there are some fruits that launch Brazil to the position of great world producer. Passion fruit is one of the crops that contribute to this condition of Brazil as a world fruit producer, with an average productivity of 14t/ha in 2018 (IBGE 2018). The average productivity of passion fruit in recent years has varied from 12 to 15 tons per hectare, with potential for production of 30 to 35 tons per hectare (Silva et al 2009). Fruit production stands out in the Northeast, Southeast, and South regions of Brazil. In the Southeast region, passion fruit is one of the eight most cultivated fruit species in the extensive system, being preceded only by the cultures of orange, banana, lemon, mango, mandarin orange, pineapple, and grape (Meletti 2011)
