Mature fruit of 295 accessions of Capsicum baccatum from the USDA/ARS Capsicum germplasm collection were characterized for fruit length, width, weight, and color. Mean fruit weight was determined to be 5.91 g with a range of 0.15 to 22.8 g. Mean fruit length was 6.01 cm with a range of 0.8 to 16.0 cm. Mean fruit width was 1.86 cm and a range of 0.5 to 4.75 cm. Distributions of all characteristics were positively skewed and failed the Kolmogorov-Smirnov test for normality. The distribution of fruit weight values was the most highly skewed, possibly reflecting a more intense human selection pressure for this characteristic. Distributions of fruit width, length, weight, and length:width were leptokurtic (long-tailed). Ninety-three percent of accessions were elongate. Mature fruit colors included red (73.6%), orange (19.7%), yellow (3%), green (0.3%), and mixed (3%). These data suggest that variability for mature fruit characteristics within this germplasm collection is considerable and that variability for fruit length, width, weight, and color is sufficient to provide the basis for the improvement of the aji crop.

Mature fruit of 330 accessions of Capsicum chinense Jacq. from the USDA/ARS Capsicum germplasm collection were characterized for fruit length, width, weight, and color. Mean fruit length was determined to be 47 mm with a range from 7.9 mm to 113.7 mm. Mean fruit width was 21.17 mm with a range of 6.18 mm to 40.0 mm. Mean fruit weight was 6.31 g with a range of 0.18 g to 22.7 g. Distributions of all characteristics were positively skewed. Distributions of fruit length, fruit weight, and fruit length/width failed the Kolmogorov-Smirnov test for normality. The distribution for fruit width was normal. Ninety-two percent of the accessions examined were elongate. Mature fruit colors included red, orange, yellow, brown (chocolate), and cream. The germplasm collection contained primarily pendent larger-fruited cultivated forms of the species, but also contained upright small-fruited primitive and semipendent transitional forms. These data define the variability for mature fruit characteristics within this germplasm collection and provide a baseline against which future introductions/acquisitions can be compared. Additional sampling of the gene pool might be expected to substantially enhance the genetic variability within the primitive forms of this species.

ABSTRACT: The aim of this study is to determine some fruit characteristics of 19 different lines hybridized by previous regular studies. These lines were examined in order to determine the differences among volatile components and reveal the differences in comparison with the parents. Plant height (cm), fruit weight (g), fruit width (mm), fruit length (mm), fruit flesh thickness (mm), pungency, immature fruit color and mature fruit color were determined of parents and F4 lines. As a result, a wide range of variations were determined between lines and parents in terms of all parameters apart from pungency. Especially in terms of volatile components, it has been found that some active substances are found only in the father and white genotype (Fenchol, spathulenol and geranyl acetate), some of them only in the mother and orange genotype (α-terpineol, dihexyl azelate and 2-hexadecanol). It was concluded that volatile compounds of the species can be used as a marker for breeding studies.

ABSTRACT This study aimed to evaluate the genetic divergence among Passiflora cristalina genotypes and quantify the relative contribution of 30 flower and fruit characteristics, seeking to support the preservation and characterization of genetic resources of the species for preservation and use in future breeding programs. We evaluated 150 fruit and 150 flowers collected in 15 genotypes with naturally occurring in the municipality of Alta Floresta, MT. The characterization of genotypes was performed through 30 morphological characteristics of flowers and fruits, 21 of these for flower and 9 for fruit. Data were evaluated using the principal components and cluster methods obtained by UPGMA method from the similarity matrix (Euclidian mean distance), using the Genes software. By principal component analysis, it has been found that the first three components have absorbed 52.11% of the accumulated variation. The characteristics that most contributed to the discrimination of genotypes were fresh fruit weight, stigma length, length of corona filaments, fruit width, petal width and pulp weight, which are more responsive for the selection of P.cristalina genotypes. Smaller contributions to diversity were obtained from anther width, bract width and fruit length. The smallest contributions for diversity were obtained from the following characteristics: anther width, bract width and fruit length. Through UPGMA clustering method, it was found that there is a large genetic divergence among genotypes analyzed because all genotypes were grouped with over 50% of dissimilarity. This study identified genotypes 4, 5 and 9 as the most divergent and therefore the most suitable for breeding in future breeding programs and genetic conservation of the species.

The total of thirteen different avocado (Persea americana Mill.) genotypes were collected for evaluating the fruit characteristics in the laboratory of Agricultural Research Station, Pakhribas during November 2017. The fully matured fruits from the farmer's field at Patle, Dhankuta were collected. The criteria for selecting the genotypes were fruit weight, fruit length, fruit diameter, seed weight, pulp weight, pulp to fruit ratio and the seed weight percentage. The result suggests the potentiality of the genotypes PAKAV002 and PAKAV010 in most of the evaluated characters as compared to the tested genotypes. The genotypes PAKAV008 and PAKAV007 were disliked as they have 32.59% and 28.39% of seed weight to the total fruit weight. The genotypes PAKAV002 and PAKAV010 had the average fruit weight ranging (307.1 g and 346.8 g), maximum of pulp to fruit ratio 62.34% and 56.97%. Similarly, genotypes PAKAV010 (11.425%), PAKAV013 (11.96%) and PAKAV002 (14.47%) had low seed weight to the total fruit weight which is regarded important factor for avocado selection and evaluation. This result shows that the genotypes PAKAV002 and PAKAV010 should be further evaluated for fruit characteristics and the quality.

Four pigmented grapefruit cultivars viz. Shamber, Flame, Star Ruby and Rio Red were evaluated at Horticultural Research Station, Sahiwal (Pakistan) for their production features encompassing growth, yield and fruit characteristics. The cultivars significantly differed for the studied physical parameters i.e. yield per plant (kg), fruit weight (g), fruit length (cm), fruit breadth (cm), peel thickness (mm), peel, juice and rag contents (%)], and biochemical traits i.e. TSS (°Brix), acidity (%) and ripening index. The highest fruit yield (84.28 kg/plant) was recorded for Star Ruby and the minimum (75.00 kg/plant) was recorded for Rio Red. The maximum fruit weight (338.92 g/fruit) was noted in Rio Red, while the maximum fruit length (9.14 cm) was found in Shamber. The highest TSS was noted for Rio Red (8.32 °Brix) followed by Shamber (7.94 °Brix). The maximum fruit acidity was observed for Star Ruby (1.00%), while the minimum for Shamber (0.94%). It was concluded that four grapefruit cultivars under consideration were divergent in their performance under prevailing conditions.

Phenotipic diversity and biometry of fruit and seeds of a natural population of Cenostigma macrophyllum Tul. The aim of this study was to characterize and estimate the phenotipic diversity of Cenostigma macrophyllum in a natural population in the state of Piauí (PI), Brazil, from the physical characteristics of the fruit and seeds. The data were collected in the municipality of Floriano, PI. The following variables were evaluated in biometry: fruit length (mm), fruit width (mm), fruit weight (g), number of seeds per sample fruit, seed length (mm), seed width (mm), and seed thickness (mm). The biometric data were analyzed by descriptive statistics, and deviations from normality of the data were confirmed by the Lilliefors test for use of the Spearman non-parametric correlation. The phenotipic divergence observed among the individuals was based on cluster analyses (Tocher and UPGMA) and principal components. According to principal components and the dendrogram, individuals 3 and 11 have the greatest dissimilarity. The variables related to the fruit (length, width, and weight) had significant positive correlation, and these variables were the ones that most contributed to intraspecific variation. The results obtained were relevant because they will assist studies related to pre-breeding and conservation of the species.

Abstract Apricot (Prunus armeniaca L.) is a world-wide highly appreciated fruit, with its attractive colour, soft texture and typical flavour. In the current investigation, 68 apricot accessions collected from Jammu and Kashmir, India were analysed to determine the measure of variation using 12 qualitative and 16 quantitative traits with an aim to identify superior apricot accessions with excellent fruit quality traits. High phenotypic variability was observed among the studied apricot accessions with significant differences among most of the qualitative and quantitative traits. Fruit-related characteristics including fruit weight, fruit length, fruit ratio, fruit firmness, fruit shape, fruit suture, stone weight, kernel weight and stone shape were the most diverse with a high coefficient of variation (>30%). One way analysis of variance showed significant differences (P < 0.0001) among all the quantitative traits. Significant positive and negative correlations were observed between all the agronomically important fruit quality traits. The principal component analysis (PCA) revealed that 75.34% of the variability was defined by the first eight components. The unweighted pair group method with arithmetic mean (UPGMA) dendrogram, based on all traits measured grouped the accessions into two main clusters with several sub-clusters. Both UPGMA dendrogram and PCA scatter plot formed a cluster of 14 accessions, having the highest values regarding most important fruit quality traits such as fruit weight, fruit length and width, fruit ratio, stone weight and kernel weight can be treated as potentially superior accessions. These accessions can be used directly for cultivation and in future apricot breeding programmes. The present findings are promising for genetic resource management, cultivar improvement and commercial applications of apricot in Jammu and Kashmir, India.

Quince (Cydonia oblonga Mill.) belongs to the Rosaceae family is native to south-eastern Europa and Asia Minor. It is generally used for table consumption and processed into jam, jelly and marmalade. It is also used as dwarfing rootstock for pear cultivars. In the present study, fruit characteristics and genetic diversity of 17 quince cultivars from Turkey were investigated. For fruit characteristics, 'Bardacik' had the highest fruit weight. The highest SSC/Acidity ratio were obtained from 'Osmancik'. There was high level of variation in fruit characteristics among cultivars. In molecular analysis, totally 133 bands were obtained from 23 sequence-related amplified polymorphism (SRAP) primer combinations and 67 of them were polymorphic. Genetic similarity of 17 cultivars was between 0.78 and 1.00. Two cultivars ('Sekergevrek' and '32S04') were found to be more distinct from the other cultivars genetically. This study showed that there was low level of genetic variation most of quince cultivars grown in Turkey. SRAP markers firstly used in quince with this study indicating that it can be used for characterization and diversity analysis of quince.

Some physico-chemical properties of ten pomegranate accessions collected from different districts in the Kurdistan region of Iraq were investigated in this paper. Considerable correlations between the characteristics studied were found and valuable pomological traits were observed. Cluster analysis showed the homonyms between some pomegranate accessions. Principle component analysis reported that the component describing the greatest variability also positively correlated with fruit weight, total aril weight, total peel weight, volume of juice, total soluble solids (TSS), fruit length, fruit diameter, pH, aril length, and 100-seed fresh weight, but negatively correlated with titratable acidity (TA). Fruit weight was firmly correlated with total aril weight, total peel weight, volume of juice, TSS, aril length, 100-seed fresh weight, fruit length and fruit diameter. The volume of juice was correlated with TSS, aril length, 100-seed fresh weight, fruit length, fruit diameter and it was observed that with an increase in the fruit size, the volume of juice increased as well. The correlation between total phenolic compounds and antioxidant capacity was not observed. The associations found among physical and chemical traits suggest that consumers should use large fruits with large arils so that they have more juice. Thus, ?Choman?, ?Raniyeh? and ?Halabja? were juicier than other accessions.
