“…A network graph of correlations was constructed from the phenotypic correlations (Rosado et al 2017) and the sensory attributes, in which the variables with positive correlations were connected by a green line and the negatives by a red line. The thickness of the lines represents the absolute value of the correlation whereby the thicker the correlation between the variables is represented by a thicker line.…”

The specialty coffee market has grown significantly in the past decades and has several cultivars with productive potential. The objective of this study was to evaluate the sensory profile of the beverage produced from Coffea arabica L. genotypes based on postharvest processing and to identify cultivars with the greatest genetic potential for coffee cultivation in the city of Araponga, Minas Gerais, Brazil. The experiment was a randomized complete block design with two replicates and 11 genotypes with different levels of resistance to rust. The sensory profile demonstrated an interaction between the genotype and the processing technique. Five of the genotypes presented total scores above 85 points according to the SCAA protocol. Moreover, two of these genotypes yielded heightened sensory notes after undergoing dry processing. The selection of coffee genotypes should consider the level of technology involved in the drying of the coffee beans, which preserves the potential quality of the beverage.

“…It can be inferred that there is a cytoplasmic effect of the female parent influencing these traits, higher seed weight may be related to higher seed reserve, and most of the genetic makeup of the endosperm is maternally, therefore the highest weight of 100 seeds observed for hybrids coming from male parents 2 and 6 is actually due to the female parents used in these crosses. Rosado et al (2017) postulate the existence of cytoplasmic effects on the control of seed emergence and vigor traits in sour passion fruit. Therefore, important to target the paternal and maternal genitor in order to obtain seeds with high germination potential in Sour Passion Fruit, according to Rosado et al (2020).…”

“…Thus, it is important to perform evaluations and selections, aiming to properly choose male and female parents, giving a higher chance of genetic gains. In selection programs, genetic diversity can be assessed early by seed physiological quality, with germination and vigor tests (Rosado et al, 2017).…”

The objective of this study was to verify the genetic influence of male parents in the expression of emergence and vigor traits of the sour passion fruit seedling, and to select the ones that contributed with the highest selection results. Controlled hybridizations were performed between genotypes of the Sour Passion Fruit Breeding Program of the Universidade Federal de Viçosa (UFV) and commercial cultivars of the Empresa Brasileira de Pesquisa e Agropecuária (Embrapa) according to Design I of Comstock and Robinson. The experiment was conducted in a completely randomized design with 24 treatments and four replications (50 seeds). The number of emerged seedlings was calculated daily to calculate emergence percentage and emergence speed index, total length of seedling (cm), length of shoot (cm) and length of main root (cm), seedling dry mass and weight of 100 seeds. The analysis of variance was performed using the Hierarchical Design Model I of Comstock and Robinson, and the combined selection for estimation of genetic gains using GENES statistical program. The Design I of Comstock and Robinson was appropriate to predict the genetic values of seedling emergence and vigor traits. Selection gains were high for the traits such as, weight of 100 seeds and dry mass per seedling. Male parents 2 and 6 were selected for most combinations.

“…Passion fruit species are known to be in the process of diversification (Bruckner et al, 1995) and evolution (Cerqueira et al, 2014;Silva et al, 2017), aided by the high capacity for interspecific hybridization and karyotype plasticity (Melo et al, 2001;Melo and Guerra, 2003). Although purple passion fruit are thought to be mostly inbreeding some outcrossing (Bruckner et al, 1995;Brum et al, 2011;de Lira et al, 2016) may have result in morphological variability (Marostega et al, 2017: Ocampo andd'Eeckenbrugge, 2017).…”

Seed Structural Variability and Germination Capacity in Passiflora edulis Sims f. edulis

2020

Purple passion fruit, Passiflora edulis Sims f. edulis, is an important semi-perennial, fruit bearing vine originating in South America that produces a commercial tropical juice pulp for international and national consumption. Within the round purple passion fruit are a large number of membranous seed sacs each containing individual seeds.Little is known about the seed anatomy of the commercial passion fruit, differences between wild collected and commercial types, and its effect on seedling germination. Therefore, our main objective for this study was to analyze the seed anatomy variability of different germplasm as well as the effect on viability and germination of the seeds of this species. Germplasm was evaluated from three sources: (1) commercial cultivars grown in current production areas, (2) genebank accession from the national seed bank, and (3) landraces collected across different high and mid-elevation sites of the Andean region. A total of 12 morphometric descriptors related to seed anatomy were evaluated on the 56 genotypes, of which three were most informative: Angle to the vertex which is related to the shape of the seed, the thickness of the tegument and the horizontal length; separating the seed according to its source of origin. Germination was found to be positively correlated with the number (r = 0.789) and depth (r = 0.854) of seed pitting. Seeds of the commercial cultivars had more seed pits and higher germination compared to seeds of landraces or genebank accessions showing a possible effect of domestication on the crop. Interestingly, passion fruits often germinate during the rainy season as escaped or wild seedlings especially in the disturbed landscapes of coffee plantations, so some dormancy is needed but faster germination is needed for intensive cultivation. Harnessing passion fruit diversity would be useful as the semi-domesticated landraces have valuable adaptation characteristics to combine with rapid germination selected in the commercial cultivars. The variability of seed pitting with cultivars more pitted than landraces possibly resulting in faster germination may indicate that purple passion fruit is still undergoing a process of selection and domestication for this trait.
