Acerola fruit is one of the richest natural sources of ascorbic acid. As a consequence, acerola fruit and its products are in demand worldwide for the production of health supplements and for the development of functional products. Acerola phenotypes (103) were screened in Western Paraná State, in the Southern region of Brazil, and evaluated to obtain information on fruit quality characteristics with the aim of using them in future breeding programs. Principal Component and Hierarchical Cluster analysis were performed on all datasets to explore the variability among samples and to identify the main clusters. A great variability among phenotypes was observed, with potential for use in breeding programs. Seven phenotypes were selected as candidates in the next breeding program, characterized by high vitamin C content and yield, or higher values of fruit size and color parameters. Four belong to cluster 1 and three to cluster 2. Specifically, two phenotypes, belonging to cluster 2, showed the best performance in terms of vitamin C (2150 mg 100 g−1 pulp and 2625 mg 100 g−1 pulp respectively) and pulp yield (74.8% and 82.3% respectively), and one phenotype, belonging to cluster 1, for high pulp yield, fruit size and vitamin C content (80.3% 6.43 g and 2490 mg 100 g−1 pulp).

Myrtus communis L. is an evergreen shrub that produces berries with a high content in antioxidant compounds. Since these compounds have demonstrated a positive effect on human health, the interest on berries and their usages has increased. However, environmental conditions may affect the productivity of these species and consequently the quality of wild myrtle. Ecotypes from diverse geographical origins may result in significant variations in terms of bioactive compounds content as well as in chemical traits. For this reason, in this work ecotypes from two different localizations have been studied to determine if their differences in morphological and anthocyanins traits can be attributed to their origin and the environmental characteristics of these locations. For this, chemometric analyses such as Hierarchical Cluster Analysis and Principal Component Analysis, were employed. The results showed differences between the ecotypes depending on their location. In particular, myrtle berries from maritime zones present greater fruit size and amount of bioactive compounds, which means an improvement in the quality of the final product based on this raw material. It can be concluded that both morphological and anthocyanins traits are related to the location of the ecotype and allow selecting the best ecotype for the required applications.

Informed assessment of priority genetic traits in plant breeding programs is important to improve the efficiency of developing cultivars suited to current climate and industry needs. The efficiency of genetic improvement is critical for perennial crops such as cranberries, as they usually involve more resources, time, and funding compared with other crops. This study investigated the relative importance of cranberry producers’ preferences for breeding traits related to fruit quality, productivity, plant physiology, and resistance to biotic and abiotic stresses. Industry responses revealed that fruit characteristics affecting fruit quality, including firmness, fruit size and anthocyanin content, and resistance to fruit rot, were the most desired traits in new cranberry cultivar release. These traits have the potential to increase the quality standards needed to process high-value sweetened dried cranberry products, positively affecting price premiums received by producers, which is critical for the economic viability of the cranberry industry. Our findings will be useful to breeders and allied scientists seeking to develop an advanced DNA-based selection strategy that would impact the global cranberry industry.

We conducted audience surveys at three major peach producer meetings across the United States. We found that the relative importance assigned to fruit quality and tree traits by producers varied across producers’ end markets. Fresh peach producers indicated fruit flavor and size were the most important fruit quality traits, whereas processed peach producers viewed fruit size, fruit firmness, and absence of split pits as being the most important traits for a successful peach cultivar. These results have potential to ensure that peach breeding programs are consonant with fresh and processed peach producers’ needs for fruit and tree traits.

Abstract In this study, walnut genotypes that selected during two growing seasons among thousands of seedlings were analyzed in terms of detailed morphometric, phenological, and chemical traits. A multivariate analysis was conducted with valuable traits for breeding and selection such as morphometric traits, chemical composition, and phenological characteristics. Also, genotypes were characterized by a retrotransposon-based iPBS marker system. The correlation analysis showed significant positive and negative correlations between agro-morphological characters. The principal component analysis explained 71.44% of the total variance into five main components. Principal component and hierarchical cluster analysis divided genotypes into three groups, whose subgroups were identified based on both agro-morphological characters and iPBS marker systems. A high level of polymorphism ratio was observed for tested markers. Mantel’s test demonstrated relatively low correlations between molecular and morphological treats (r=0.04). The genetic similarities among all individuals ranged from 0.39 (between 018 and 015 or 045 genotypes) to 0.98 (between 090 and 094 genotypes) with a mean similarity of 0.67. Remarkable phenotypic and molecular variations were observed among the genotypes. The features of some investigated genotypes were above the acceptable thresholds for walnut selection in breeding programs and our study indicated that iPBS markers can be beneficial in walnut breeding programs, allowing the evaluation of the genetic relationship between genotypes, helping to differentiate and select the best genotypes to improve agronomic properties.

Pepper Plants

Pepper plants experience complex environmental factors including abiotic and biotic stresses in field and the importance of climate changes including low and high temperatures has been emerged. Low temperature stress in the growth and development is one of the most critical issues, which directly impact on the crop yield and productivity of pepper plants. It is essential to select and breed low temperature-(LT) tolerant pepper (Capsicum annuum L.) cultivars. The research was performed to assess the agronomical traits of 39 pepper accessions belonging to chili and bell fruit types which cultivated two different night temperature set-points at 15°C for suboptimal temperature (CT) and at 10°C for low temperature (LT), respectively. Plant heights (PH) of most pepper accessions in LT were significantly decreased compared to those in CT. The stem diameter (SD) and the length of main axis (LMA) were various depending on the genotypes under LT. Moreover, the number of flowers (NFL), the total number of fruits (NFR), fruit yield (FY), fruit fresh weight (FFW), fruit length (FL), fruit diameter (FD), and the number of seeds in a fruit (NSF) were notably declined in LT compared to CT. The evaluated agronomical traits between LT and CT were further applied for the correlation analysis, the principal component analysis (PCA), and the hierarchical cluster analysis. Notably, FY trait was correlated with other reproductive traits including NFR, FFW, FD, and FL on positive directions and LT treated-39 pepper accessions were clustered into seven groups by the clustering analysis. The selected accessions were primarily involved with the positive trends with the reproductive index including NFR, FL, FD, and FW traits and would be used for pepper breeding programs on developing LT-tolerant cultivars.

BACKGROUND: In the Mediterranean basin, the solar radiation received is very high for many tree species over several hours of the day during the summer. Using a photoselective net can improve the climatic conditions and also modify the quality of light received. OBJECTIVE: This study aimed to evaluate the influence of the colour of photoselective nets on the yield and quality of Actinidia chinensis. MATERIALS: The experiment was carried out in Southern Italy on an orchard of Jintao kiwifruit. Photoselective nets of different colours were used: black, red, yellow, white, and grey. The resulting fruits were compared to those of plants in the open field. A randomised block design was adopted. Environmental, vegetative, and leaf gas exchange parameters; yield; and fruit quality were defined. All data were analysed using the Variance Analysis (ANOVA) and the Principal Component Analysis (PCA). RESULTS: Photoselectivity influenced production. The best results were obtained under the red net in terms of production and fertility indices. Fruit size, maturation indices, and nutraceutical parameters were also higher under the red net. Among the nets, the grey net induced the worst tree productivity results and the worst fruit quality parameters. However, all nets showed better results compared to the open field. CONCLUSION: The photoselective net strongly influenced the yield and quality of Jintao kiwifruit and the better results compared to the open field. The red net proved to be the best performer for the environment where the experiment was carried out.

ABSTRACT Floral management using the growth regulator paclobutrazol may be an alternative for promoting the uniformity of flowering and fruiting in West Indian cherry (Malpighia emarginata D.C.) plants. However, the effects of its use on fruit quality are still unknown. This study aimed to evaluate the effect of paclobutrazol doses on the fruit quality of M. emarginata. The experimental design was randomized blocks, in a 2 x 5 factorial arrangement, with three replications and three plants per plot, with the studied factors consisting of two M. emarginata cultivars ('Junko' and 'Flor Branca') and five paclobutrazol doses (0, 0.4, 0.8, 1.2 and 1.6 g a.i. m-1 of canopy diameter). The following variables were evaluated: fruit mass, fruit transverse and longitudinal diameters, pH, soluble solids content, titratable acidity, soluble solids/titratable acidity ratio and vitamin C content. The use of paclobutrazol, to some extent, promoted the increase of fruit mass, longitudinal diameter and soluble solids contents. The 'Junko' cultivar presented a higher vitamin C content than that for 'Flor Branca', and the maximum vitamin C contents were obtained with the paclobutrazol doses of 0.64 and 0.81 g a.i. m-1, respectively for the 'Junko' and 'Flor Branca' cultivars. None of the studied factors promoted differences for pH and fruit acidity.

Nutraceutical Properties

Pomegranate is gaining popularity because of its proved nutraceutical properties and is highly adaptable to different climates. In southern Jalisco, Mexico, 18 genotypes were characterized on the basis of fruit characteristics (21 traits) and AFLP (Amplified Fragment length polymorphism) markers. The first three components of a principal components analysis (PCA) explained 71.5% of the variation. The most important variables were related to fruit size and weight. Fruit weight, equatorial diameter, polar diameter, and rind and membrane weight were the variables that most contributed to principal component one (PC1) 46.4%. The variables juice per fruit, edible proportion, proportion of rind and membrane, and seed length contributed most to principal component two (PC2) 15.2%, while juice pH, weight of one seed, and aril width contributed the most to principal component three (PC3) 9.9%. With the six combinations of AFLP primers, 315 fragments were obtained (an average of 52.5 fragments per primer); of these, 229 were polymorphic (72.7% polymorphism). Grouping by both morphological traits and AFLP markers separated all the evaluated individuals so that there were no repeated genotypes. In both analyses, the grouping did not obey geographic origin of the genotypes (r = −0.35), suggesting that both techniques were useful and complementary in the characterization of pomegranate genotypes. The commercial cultivars Wonderful and Apaseo had low levels of similarity to genotypes from southern Jalisco. The level of polymorphism found and compared with the results obtained by other authors suggests that the pomegranate genotypes evaluated are highly polymorphic. We found broad genetic diversity that can be used in breeding programs.

The present study aimed to evaluate different agro-morphological traits among twenty genotypes of Curcuma aeruginosa Roxb. and three varieties of Curcuma zanthorrhiza Roxb. Agro-morphological data traits were investigated based on qualitative and quantitative parameters from PPVFRA descriptors with modification. All the recorded data was analyzed through SPSS 16.0 and R 3.4.2 for ANOVA and similarity analysis, respectively. Significant differences (P <0.05) were observed in the traits studied of the habit of the rhizome, the shape of the rhizome, length of primary rhizome, number of mother rhizome, plant height, pseudostem diameter, number of leaves, leaf length, leaf width, and number of shoots. Hierarchical cluster analysis (HCA) classified the genotypes into three groups. The principal component analysis (PCA) were showed consistent with results of the HCA. These genotypes could be used as novel genotype in agricultural biochemistry for breeding programs.
