Varate Giduga is one of the unique variety from Sirsi region of Karnataka. The tree is Semi-circular shaped with dense foliage, leaves about 25cm long; dark green in colour with wavy margin. It is a very consistent and heavy producer. The fruit of this tree matures by mid-April and fruit has a distinctive yellow skin color on fruit exposed to the sun. The fruit shape is round, fruit weight ranged from 350-400 g, fruit length was 9.8 cm, fruit diameter was 9.2 cm, fruit thickness was 8.0cm and bisexual flowers were 16.53%. Biochemical constituents such as the total phenols (317.50 mg/100 g), flavonoids (5.79 mg/100g), carotenoids (1.46 mg/100 g) and acidity (0.19%) were recorded which suggests that these characters are unique as compared to other varieties. The fruit skin is rough and glossy in appearance and the fruit has little or no fiber. It is very delicious in taste with high pulp percentage (74.0%) and high TSS (23.4º B). The flesh color is orange. The fruits have deep orange firm pulp and very sweet with pleasant flavor. Besides,several other traits have drawn special attention to this mango variety as it has large sized fruits (Fig-1), late variety with very good taste, fruit can be cut into two halves by retaining the stone in one half, regular bearer and fruit fly resistant genotype because of its thick peel and high phenolic content in pulp (317.50 mg/100 g).

  A study was conducted on twenty five genotypes of seedling Mangoes to examine fruit morphological characters. Fruit shape of the evaluated germplasm varied enormously and fruits of obovoid, elliptic, round and oblong shapes were found. Fruit apex shape in the evaluated plants was round, acute and obtuse. Depth of fruit stalk cavity was either absent, shallow and of medium type, whereas, fruit neck prominence was absent to slightly prominent in the tested plants. Shape of fruit ventral shoulder was varied and found to be slopping abruptly, rising and then rounded and long curve type in the evaluated germplasm. Fruit beak varies from pointed to perceptible type and fruit sinus was absent to shallow type in the fruits from different plants. Fruit attractiveness varies from very good to excellent and fruit colour from greenish yellow to green colour of fruit skin at maturity was noted in fruits from selected trees. Peel colour of AA-15 was different amongst all the genotypes which were green with red blush. Pulp colour varied from light orange, yellow orange, orange yellow, yellow and light yellow, whereas, pulp texture was soft to intermediate in the evaluated germplasm.

In semiarid apple (Malus domestica) growing regions, high temperatures and excessive solar radiation can increase the risk of sunburn development. Protective netting is increasingly used as a cultural practice under these conditions to mitigate fruit sunburn losses. However, fruit skin color development can be negatively affected under protective nets due to the reduction in light availability. Reflective groundcovers have been previously reported to increase fruit color development, particularly in the inner parts of the tree canopy. Here, we compared two types of reflective groundcover: a woven polyethylene fabric and a film material with a grassed control without reflective material under a protective netting installation that reduced photosynthetically active radiation (PAR) by 17%. The experiment was conducted in a semiarid climate on a 5-year-old ‘Cameron Select Honeycrisp’ apple orchard near Quincy, WA. Light penetration into the canopy was measured with a PAR sensor. At harvest, fruit quality, yield, and size were assessed. The use of reflective groundcover between the rows significantly increased reflected PAR into the lower canopy. Moreover, reflective groundcovers significantly increased the amount of fruit with greater than 25% skin red color compared with the control. Reflective groundcover did not affect fruit weight, yield, and fruit number. The use of reflective groundcover under protective netting can increase light penetration into the canopy, thereby improving fruit skin red coloration in apple.

The objective of this research was to determine whether immediate cooling of mangoes (Mangifera indica L.) in water or air affected survival of Mexican fruit fly (Anastrepha ludens Loew) larvae. Two tests were conducted with mortality of late third instar Mexican fruit fly larvae evaluated after infested mangoes were immersed in 46.1 °C water for 65, 75, or 90 minutes depending on fruit weight and immediately cooled in water or air at 22 to 26.5 °C. Results suggest a need to amend the current hot water quarantine dip treatment schedule to require cooling of fruit for 30 minutes in air. We suggest a 25-g allowance in maximum permitted fruit weight be established for the 65-, 75-, and 90-minute dips and a monitoring system used to ensure compliance. Synchronization between maximum permitted fruit weight for each hot water dip duration and commercial sizing practices would facilitate monitoring of fruit weight. We also recommend confirmation of efficacy for the 75-minute treatment of flat-elongated mangoes that weigh 375-570 g.

Abstract Summer apples are one of the most important plant community in Artvin province located Northeastern part of Turkey. In present study 22 local apple genotypes were characterized by phenological, morphological, biochemical and sensory properties. Harvest date was the main phenological data. Morphological measurements included fruit weight, fruit shape, fruit ground color, fruit over color, fruit over color coverage and fruit firmness, respectively. Sensory measurements were as juiciness and aroma and biochemical characteristics included organic acids, SSC (Soluble Solid Content), vitamin C, total phenolic content and antioxidant capacity. Genotypes exhibited variable harvest dates ranging from 11 July to 13 August and cv. Summered harvested 30 July 2017. The majority of genotypes were harvested before cv. Summered. Fruit weight were also quite variable among genotypes which found to be between 89 g and 132 g, and most of the genotypes had bigger fruits than cv. Summered. Pink, red, yellow and green fruit skin color was evident and main fruit shape were determined as round, conic and oblate among genotypes. ART08-9, ART08-4, ART08-21 and ART08-22 had distinct bigger fruits and ART08-1, ART08-2, ART08-5, ART08-12 and ART08-17 had higher total phenolic content and antioxidant capacity. The results of the study showed significant differences for most of the phenological, morphological, sensory and biochemical characteristics. Thus, the phonological, morphological, sensory and biochemical characteristics of summer apple genotypes were distinguishable and these results suggest that phonological, morphological, sensory and biochemical differences of the summer apple genotypes can be attributed to differences in genetic background of genotypes which placed different groups by PCoA analysis.

Many trials to supply selenium to fruit have been carried out since tests have confirmed selenium's role as a medical substance. Supplying selenium in orchards by soil and foliar application was not effective because of loss from rainfall. In order to increase selenium absorption by fruit, this study carried out tree trunk injections during the growing season. Selenium solutions in concentrations of 5, 10, 25, and 50 mg·L–1 were supplied to `Niitaka' pear (Pyruspyrifolia) trees by trunk injection (1.5 L/tree) four times at 15-day intervals from June 2004. The treatment with 50 mg·L–1 selenium showed necrosis symptoms at leaf-margins after secondary treatment and toxicity as abnormally red fruit skin color. Fruit weight and leaf area were decreased by selenium treatments, while severe symptoms appeared with higher selenium concentrations. Hunter values `a' and `b' in fruit skin color were increased by selenium treatment in comparison to the control. The selenium treatment showed lower soluble solids by as much as 1.2%, and higher fruit firmness. Selenium concentration in pear fruit was increased by trunk injection with a 5 mg·L–1 solution. The bound selenium in pear fruit after 3 months of storage in cold room conditions was very high, but free selenium was low.

Bottle gourd [Lagenaria siceraria (Molina) Standl.] is one of the most interesting species in the plant kingdom, due to the diversity of fruit shapes, sizes and ways of use. Warty genotypes are rare compared to non warty genotypes. Considering unusual external appearance of warty fruits, we focused our research on the investigation of its inheritance patterns. By crossing different bottle gourd phenotypes, we studied the mode of inheritance and identified and verified genes responsible for the fruit skin color and warty phenotype segregation. Two parental lines, LAG 70 (with warty fruit of light green color) and LAG 71 (smooth fruit, variegated), F1, F2 and backcrosses populations along with both parents were evaluated. Genetic analysis indicated that warty fruit type is a result of monogenic inheritance, whereby the warty fruit type is dominant (Wt) trait over to the non-warty fruit type (wt). The mode of inheritance of fruit color was controlled by recessive epistasis, with a ratio of 9 variegated (A-, B-), 3 dark green colored (aaB-) and 4 light green colored (aabb) fruits in the F2 generation.

Afghanistan assumed to be a part of the diversity center of Central Asian group of apricots but due to lack of proper collection, precise detection and documentation of distinct variability, the apricot diversity in the country is under unknown and unprecedented threat. This study, therefore, was run in Badam-Bagh research station for two consecutive seasons (2016-2017) to assess 28 various characters of 20 native Afghan apricot accessions. Results showed a high variability among studied genotypes. Leaf and fruit characteristics such as leaf blade length, leaf blade width, fruit weight, kernel weight, mesocarp percentage, kernel bitterness and fruit quality like total soluble solids, pH, and titratable acidity, skin color and fruit shape which subsequently determines customer appeal and marketability, displayed huge variation. Based on fruit weight, there were two groups of apricot genotypes; small fruits (<37 g) and large fruits (>37 g). Accessions with large fruits embrace: “Amiri”, “Bid-Mushk”, “Hassan-Khili”, “Jibraelli”, “Koorpa”, “Qandak”, “Pir-Naqshi”, “Seyed-Abadi”, “Salari-Sorkh”, and “Saqi”. Most genotypes were early flowering and intermediately ripening in nature. Kernels of only “Walayati” accession had strong bitterness and remained were sweet-kernelled. The mesocarps of most accessions were very weakly adhered to stones. PCA showed 86.15% of total variance among genotypes to be due to first seven components. UPGMA cluster analysis separated 20 accessions into 2 main groups (13 accessions in the first and 7 accessions in the second groups). The results exhibited that morphological characters of leaf and fruit and pomological characters are of immense importance in fast and easy description of apricot genotypes. This is per se the first study on genetic diversity of apricot accessions performed in Afghanistan. The results would provide opportunity for apricot breeders to select accessions with elite and premium characters in terms of marketability and adaptability for particular growing sites.
