In this paper are presented three years data (2009-2011) of biological traits of 30 cornelian cherry genotypes selected from the natural population of the region Upper Polimlje in Montenegro. Time of maturity, cropping, fruit and stone weight, size, fruit shape index and peel colour, content of flesh in total fruit mass and the soluble solids continent are presented. The aim of this paper is selection and preservation of cornelian cherry genotypes from natural population of Upper Polimlje that deserve attention due to their biological traits and recommendation of these genotypes for future propagation in present agricultural conditions or as a starting material in breeding of this fruit species. Genotypes BA 70, BP 04, BP 17 and BP 44 with high cropping coefficient from 0.34 to 0.50 are worthy of attention as a big biological potential. For table consumption genotypes BA 70 and BP 21 are interesting, with fruit weight above 4 g, and genotypes PL 98, BP 44, PL 99, BP 36 and BP 22 with content of flesh in total fruit mass above 89% for processing. High content of soluble solids in the fruit, above 19%, are characteristic for genotypes BP 01, BP 06, BA 13, BP 38 and BP 40.

Cornelian cherry is a little-known plant that can be grown in Poland both on a commercial and amateur scale. The commercial cornelian cherry plantations should be established using selected cultivars or vegetatively propagated valuable ecotypes, as only this guarantees a uniform yield, maturation and standardization of fruit quality. The experiment was carried out in 2014 and 2015 in the private plantation of cornelian cherry (Cornus mas L.) located in Dąbrowica, near Lublin (22.454 N; 51.270 E). The subject of the research were ecotypes No.: 1, 2, 3, 4, 5, 6, 7, 10, 11, 14, 15 obtained as seedlings in 1998. Cornelian cherry plants obtained from seeds differed very much in the yield and quality of fruit. The fruit characteristics for the examined ecotypes ranged to 1.63–2.21 g for fruit weight, 1.30–1.61 for fruit shape index, 10.13–15.32% for content of stone, 17.85–22.68% for soluble solids content (SSC), 2.32–3.0% for titratable acidity (TA), 6.59–8.36 for SSC/TA, 54.9–75.97 for vitamin C content. Among the ecotypes studied in terms of external fruit features, ecotypes No. 3 and 4 were distinguished due to the largest fruits (mass and diameter) and relatively small share of the stone in the whole mass of the fruit. However, due to the chemical composition, the fruits of ecotype No. 5 were distinguished by the content of extract, extract to acids ratio, sugar, dry matter, anthocyanins and vitamin C content. These fruits enjoyed 55% strong acceptability among adults. The indicated ecotypes can be used in breeding as well as in nursery for obtaining valuable varieties of cornelian cherry for production in Poland.

Although the Cornelian Cherry is widely grown in the north-eastern areas of Iran, it is not recognized as an important fruit crop as are many other fruit species. Large variability has been observed in all morphological and chemical compositions under study. Fruit weight varied from 1.499 to 3.29 g, whereas seed weight ranged from 0.249 to 0.425 g. The average lengths of fruits were between 15.22 and 22.31 mm, and the average widths of them were between 10.26-16.3 mm. The content of ascorbic acid ranged from 240-360 mg/ 100 g fresh weight. The total soluble solids and total acidity were 5-12.5% and 0.43-1.86% respectively. Grouping of Cornelian Cherry accessions based on 5 factors was performed and were divided into three sub-clusters. The results obtained from this study might be helpful for Cornelian Cherry breeders trying to develop new genotypes and varieties.

A melon (Cucumis melo L.) genomic library of near-isogenic lines derived from the cross between the Spanish cultivar Piel de Sapo and the exotic accession PI 161375 has been evaluated for fruit quality traits in four different locations. Traits evaluated were fruit weight, soluble solids content, maximum fruit diameter, fruit length, fruit shape index, ovary shape index, external color, and flesh color. Among these traits, soluble solids content showed the highest genotype × environment interaction, whereas genotype × environment interactions for fruit shape and fruit weight were low. Heritability was high for all traits except soluble solids content, with the highest value for fruit shape and ovary shape. Ten to 15 quantitative trait loci were detected for soluble solids content, fruit diameter, fruit length, and fruit shape; and four to five for ovary shape, external color, and flesh color. Depending on the trait, between 13% and 40% of the detected quantitative trait alleles from PI 161375 increased the trait, and between 60% and 87% of them decreased it, resulting in some PI 161375 alleles of interest for breeding. Most of the quantitative trait loci detected in previous experiments could be verified with the near-isogenic line population. Future studies with the melon near-isogenic line genomic library will provide a better understanding of the genetic control of melon fruit quality in a wider context related to agronomy, genetics, genomics and metabolomics studies.

Abstract Pumpkin is a popular vegetable crop and exhibits a broad diversity in fruit shape and size. Fruit-related traits are the decisive factors determining consumer acceptance and market value of pumpkin cultivar. As a result, deciphering the genetic basis of fruit-related traits is of great importance for pumpkin breeding. To address this problem, a F2 population was generated by two Cucurbita moschata inbred lines with contrasting fruit shapes and genotyping-by-sequencing approach were used to construct a high-density genetic map and localize the QTLs underlying the fruit-related traits in this study. The results showed that a high-quality genetic map was constructed for pumpkin, which comprised of 2413 bins and spanned a total length of 2252.10 cM with an average genetic distance of 0.94 cM. A total of 30 significant QTLs with moderate or small effects were identified for 7 fruit-related traits, including fruit length, fruit diameter, fruit shape index, fruit weight, fruit flesh thickness, seed cavity size, and total soluble solids content. Co-locations and close locations were observed between the QTLs underlying different traits, demonstrating that pleiotropic effect plays an important role in genetic control of fruit-related traits. The identified QTLs provide valuable information for further fine mapping of the related genes and pumpkin breeding programs with the aim of improving fruit quality.

Flower Thinning

Ammonium and potassium thiosulfate are used commercially or experimentally as flower thinners because they are considered user, environment and consumer safe. The thinning trials were conducted in 2009 and 2010, on three- and four-year-old Braeburn Mariri Red* trees. The chemicals were applied at 1%, 2% and 3% rates of ammonium and 0.5%, 1% and 1.5% of potassium thiosulfate. Both thinning agents reduced fruit set, but were more efficient in 2009, when applied at 20% full bloom, than in 2010, when they were applied at 80% full bloom. Flower thinning with ammonium and potassium thiosulfate increased the average fruit weight, but the highest chemical rates retarded fruit growth. Ammonium and potassium thiosulfate did not affect fruit shape and firmness, but they increased starch degradation, total soluble solids content and titratable acidity. The treatments increased the percentage of flower buds, except at the highest chemical rates, where leaf damage reduced flower bud formation. Ammonium or potassium thiosulfate application may be recommended as the first step in a chemical thinning program

ABSTRACT The use of dwarf lines to obtain mini-tomato hybrids has provided agronomic and economic benefits. In Brazil, round tomatoes predominate over other varieties. The benefits of using a dwarf parent in round tomato hybrids has yet to be explored, making it important to develop dwarf round tomato lines. Backcrossing is the most suitable method to develop these lines. Evaluation and selection of the dwarf populations can improve the development of such lines. Thus, the aim of this study was to select BC1F2 populations of dwarf round tomatoes with agronomic potential and high-quality fruit. The study was conducted at the Vegetable Experimental Station of the Federal University of Uberlândia (UFU). A randomized block design was used, with 15 treatments and three replicates. The genetic material analyzed consisted of 12 BC1F2 dwarf tomato populations, plus both parents (recurrent and donor) and a commercial hybrid. The characteristics assessed were: average fruit weight (g), total soluble solids (ºBrix), number of locules (locules per fruit-1), fruit shape, pulp thickness (cm), longitudinal (cm) and transverse fruit diameter (cm), internode length (cm) and plant height (cm). The data were submitted to mean testing, multivariate analyses and a selection index. In general, average fruit weight in the dwarf populations increased significantly after the first backcross, with some fruits exhibiting a similar shape to round tomatoes. Selection of the populations UFU-DTOM7, UFU-DTOM10, UFU-DTOM5, UFU-DTOM9, and UFU-DTOM3 resulted in an estimated 6% increase in the number of locules, transverse diameter, TD/LD ratio and average fruit weight. The BC1F2 dwarf populations UFU-DTOM7 and UFU-DTOM10 were the most promising for develop inbred lines with round fruits. Despite the considerable progress achieved in this study, we suggest a second backcross, in order to obtain lines and, posteriorly, hybrids with round fruits and compact plants.

Soil Pathogens

Production of Capsicum annuum peppers is often limited, especially in tropical environments, by susceptibility to soil pathogens including Ralstonia solanacearum. Grafting desirable cultivars onto selected rootstocks can increase adaptation to abiotic stress and is an alternative to pesticides for managing soilborne pathogens. Cultivars of two other pepper species, Capsicum baccatum and Capsicum chinense, are tolerant or resistant to an array of soilborne pathogens and have potential as rootstocks; however, knowledge of how interspecific grafting may affect scion fruit quality is lacking. Flowering time, yield, and fruit quality characteristics were evaluated in 2017 and 2020 for C. annuum cultivars Dulcitico, Nathalie (2017), Gypsy (2020), and California Wonder used as scions grafted onto Aji Rico (C. baccatum) and Primero Red (C. chinense) rootstocks, including self-grafted and nongrafted scion checks. In 2020, the rootstocks per se were evaluated. The two rootstocks (‘Aji Rico’ and ‘Primero Red’), three scions, and self- and nongrafted scions were evaluated using a factorial, replicated, completely randomized design in fields at the West Madison and Eagle Heights Agricultural Research Stations located in Madison, WI, in 2017 and 2020, respectively. Differences among the main effects for scion fruit quality characteristics were consistent with cultivar descriptions. No scion × rootstock interactions were observed. Rootstocks did not result in changes in total fruit number, yield, fruit shape (length-to-width ratio), or soluble solids of scion fruit compared with self- and nongrafted checks. The rootstock ‘Primero Red’ increased fruit weight and decreased time to flowering regardless of scion compared with self- and nongrafted checks. All scions were sweet (nonpungent) cultivars and both rootstocks were pungent cultivars. No capsaicinoids were detected in the fruit of sweet pepper scions grafted onto pungent pepper rootstocks. The results indicate that interspecific grafts involving ‘Aji Rico’ and ‘Primero Red’ will not have deleterious effects on fruit quality characteristics of sweet pepper scions.

Physicochemical and sensory attributes of fully mature honey dew melon (Cucumis melo L. var. inodorus Naud.) fruits were evaluated 10 days after storage for eight commercial cultivars grown in two locations. Cultivars varied in degree of pref- erence expressed by panelists' ratings for overall fruit preference, flavor, and shape and for physicochemical measurements of soluble solids concentration (SSC), flesh firmness, and fruit weight. The sensory attribute that correlated most strongly with overall fruit preference was fruit flavor (r = 0.97). The whiteness of epidermal tissue (rind L value) and SSC correlated more highly with overall fruit preference (r = 0.54 and r = 0.52, respectively) than other physicochemical attributes, such as fruit firm- ness (r = -0.24) and fruit weight (r = -0.12). Epidermal L value correlated more strongly with panelists' ratings for fruit shape (r = 0.69) than with fruit flavor (r = 0.35), but SSC correlated more strongly with fruit flavor (r = 0.61) than with fruit shape (r = 0.30). Superior honey dew melon quality at harvest was associated with high SSC, white epidermal tissue, and round fruit shape.

The productivity of tomato is influenced mainly by environmental factors, agronomic practices and cultivar potential. Accordingly, a field experiment was conducted at Mizan-Aman, southern Ethiopia in  2016/ 2017 to evaluate the effect of intra-row spacing (20, 30, 40 and 50 cm) on the performance of three tomato varieties(Fetan, Bishola and Roma VF) with the constant inter-row spacing of 70 cm in completely randomized block design with three replications. Data on crop phenology, growth performance, yield and quality parameters were recorded and subjected to analysis of variance using SAS version-9 software. Results of the study indicated that both intra-row spacing and variety had a significant effect on phenology as well as parameters including; the number of branches, the number of fruit cluster and fruit per plant, fruit weight, total fruit yield, marketable and unmarketable yield and total soluble solids (TSS). However, the number of fruits per cluster, fruit shape index, titratable acidity (TA) and pH were significantly different only among varieties, while plant height was significantly affected by intra-row spacing. Closer spacing enhanced early maturity, while wider intra-row (50 cm) produced a maximum number of branches, cluster and fruits per plant, fruit weight, unmarketable yield and TSS. Generally, 20 and 30 cm intra-row spacing was found to be suitable for the production of maximum total and marketable yield. From the three tomato varieties, Fetan was early maturing with the highest total and marketable yield. The varieties were also significantly different in fruit weight, with the highest value obtained from Bishola followed by Fetan. The outcome of this study revealed that, the intra-row spacing of.30 cm and variety Fetan could be promoted for production in Mizan-Aman and similar agro-ecologies.

Over a three-year period yield components and pomologic properties were studied in 20 raspberry seedlings obtained by open pollination of Meeker`s yellow clone. The primary goals of this research were to determine its variability components, coefficients of genetic and phenotypic variation and coefficient of heritability in a broader sense. The analysis of the components of total variance evidenced that higher proportion of genotypic variance was found with fruit shape index (30.84%) and sucrose content (35.61%). The results revealed that genotypic coefficient of variation were less than its corresponding estimates of phenotypic coefficient of variation for all traits which indicated significant role of environment in the expression of these characters. The values of heritability coefficients, in a broader sense, were high except for number of flowers per inflorescens (9.47%), titratable acidity (6.38%) and inverted sugar content (28.88%). Nine characters had h2 in interval from 50 to 80% but for fruit weight and fruit length was greater than 80% which implies the high potential of genetic improvement in those traits.
