Productivity, fruit physicochemical quality and distinctiveness of passion fruit populations/Produtividade, qualidade fisico-quimica de frutos e distinguibilidade de populacoes de maracujazeiro-azedo

The productivity and physicochemical quality evaluation is important, as it identifies superior populations. However, launching products requires following the descriptors according to DHE test instructions. Thus, this study aimed to evaluate three passion fruit populations with high productivity and physicochemical quality characteristics for commercial launch. The experiment was conducted at the State University of Mato Grosso experimental area, located in the municipality of Tangara da Serra, MT. The experimental design was complete randomized block design with four replicates and ten plants per plot. The physicochemical characteristics were submitted to analysis of variance and compared by the Tukey test. For the distinctiveness test, 25 descriptors were evaluated, where quantitative data have been converted into multicategoric data to obtain the dissimilarity matrix. From the dissimilarity matrix, groups were formed using the Tocher and UPGMA methods, Livestock and Supply Department. The highest productivity and number of fruits were verified for BRS Rubi Cerrado cultivar and UNEMAT S10 population. Populations and cultivars presented physicochemical characteristics that meet the required quality for both fresh consumption and industry use. Based on the distinction test among genotype, it was observed that the descriptors were effective for population differentiation. UNEMAT S10 population has characteristics that distinguish it from other cultivars and populations evaluated, and presents high agronomic performance; therefore, it can be launched as a commercial cultivar.

Porem, para lancar material, e necessario seguir os descritores conforme as instrucoes para a execucao dos ensaios de DHE. Desta maneira, objetivou-se avaliar tres populacoes de maracujazeiro-azedo que apresentem caracteristicas de alta produtividade e qualidade fisico-quimica, para lancamento comercial. O experimento foi conduzido na area experimental da Universidade do Estado de Mato Grosso, situada no municipio de Tangara da Serra-MT. O delineamento experimental foi o de blocos completos casualizados, com quatro repeticoes e dez plantas por parcela. As caracteristicas fisico-quimicas foram submetidas a analise de variancia e comparadas pelo teste de Tukey. Para avaliar a distinguibilidad
