“…UNEMAT S10 population showed distinctiveness from the other cultivars and populations evaluated and high agronomic performance, being able to be launched as commercial cultivar. To characterize P. edulis genotypes, Castro et al (2012) selected minimum morphological descriptors to differentiate passion fruit varieties. This result was obtained through principal components analysis, which indicated 22 of the 28 descriptors analyzed for the characterization of P. edulis with high contribution in the total variation.…”

-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 Tangará 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.

PRODUTIVIDADE, QUALIDADE FÍSICO-QUÍMICA DE FRUTOS E DISTINGUIBILIDADE DE POPULAÇÕES DE MARACUJAZEIRO-AZEDORESUMO -A avaliação da produtividade e da qualidade físico-química apresenta importância, pois permite identificar populações superiores. Porém, para lançar material, é necessário seguir os descritores conforme as instruções para a execução dos ensaios de DHE. Desta maneira, objetivou-se avaliar três populações de maracujazeiro-azedo que apresentem características de alta produtividade e qualidade físico-química, para lançamento comercial. O experimento foi conduzido na área experimental da Universidade do Estado de Mato Grosso, situada no município de Tangará da Serra-MT. O delineamento experimental foi o de blocos completos casualizados, com quatro repetições e dez plantas por parcela. As características físico-químicas foram submetidas à análise de variância e comparadas pelo teste de Tukey. Para avaliar a distinguibilidade, foram utilizados 25 descritores, onde os dados quantitativos foram convertidos em multicategóricos, visando a obter matriz de dissimilaridade. A partir da matriz de dissimilaridade, formaram-se grupos pelo método de Tocher e UPGMA. A maior produtividade e o maior número de frutos foram verificados na cultivar BRS Rubi do Cerrado e na população UNEMAT S10. As populações e as cultivares apresentaram características físico-químicas que ate...

“…Further, the relatively higher correlation value of this trait in the second principal component compared to that in the first principal component can be interpreted to mean the reliability of the second component in discrimination based on this trait. The overall low values for the each trait eigen can be attributed to the low number of traits under evaluation [18].…”

The passion fruit was introduced to Kenya through Europe in the 1920s, and only gained significant economic importance in the 1990s. Several species of the genus Passiflora present potential superior characteristics for genetic breeding of the passion fruit germplasm. Quantitative morpho-agronomic traits are important in passion fruit breeding since they allow for discrimination of varieties for important parameters that are useful in selection of fruit for market. The present study aimed at evaluating existing phenotypic variation between the Purple and Brazil varieties as well as their hybrids, developed by the Kenya Agricultural and Livestock Research Organization (KALRO). Seven quantitative morpho-agronomic traits were targeted with replication per plant and variety. Principal component technique and cluster analysis statistical tools of Minitab 17.0 software were used to discriminate the accessions under study based on the morpho-agronomic traits. Both the dendrogram and scatter plot clustered accessions based on their respective varieties, an indication of phenotypic relatedness within varieties. The results of this study will supplement the current body of knowledge on Kenyan passion fruit breeding.

“…Morphological and agronomic characterization of germplasm as well as new varieties using descriptors is a key consideration in breeding programs. The term descriptor is used to refer to a character or attribute that is used to discriminate between varieties, with redundant descriptors being seen during evaluation of many traits and thus many descriptors are judged accordingly as unnecessary due to their low contribution to variability [18][19][20]. Elimination of redundant descriptors is an important strategy in that it ensures reduction of the work required to collect data without causing significant losses in genotype discrimination [20,21].…”

Phenotypic characterization is crucial in determination of variability of hybrid varieties and their parents. The objective of this study was to determine phenotypic variation among known genotypes of both parent and KPF hybrids, as well as genotypes collected mainly from Embu County which is one of the growing areas of hybrid varieties developed by KALRO. Analysis was done using Minitab 17.0 software. Six out of seven morpho-agronomic descriptors evaluated, showed significant differences among the genotypes under study. A dendrogram based on the 7 morpho-agronomic descriptors discriminated the genotypes into two main clusters with one main cluster (II) carrying only 2 genotypes. Principal component analysis corroborated the findings of the dendrogram, distantly placing the two genotypes further from the other genotypes.
