ABSTRACTPotassium (K) is a mineral nutrient needed by crops that influences the quality of fruits and vegetables. The objective of this study was to elucidate the interaction effects of genotype by KNO3 treatment (G × KNO3) on fruit traits of melon. The experiment was conducted from August to October 2016 at Tajur II Experimental Station of IPB, Bogor, following a split plot design with three replicates. The main plot was two levels of KNO3 and the subplot was eight genotypes, consisting of seven test genotypes and one check variety (Eagle). The KNO3 treatments were applied weekly, started from 7-49 DAP with 5 g L-1 concentration, ±200 ml plant-1. G × KNO3 interaction effects were significant for sugar content and titratable acidity (TA). P34 had relatively high sugar content and TA. P25 showed a significant increase of sugar content when KNO3 is added, while Eagle, P311, and P34 showed significant decrease of sugar content. Days to male flowering, days to hermaphrodite flowering, and fruit weight had high broad sense heritability (repeatability), while days to harvest, fruit diameter, flesh thickness, rind thickness, and sugar content had moderate heritability. Fruit weight had significant positive correlation with fruit diameter, flesh thickness, and rind thickness. Application of KNO3 fertilizer in practical is therefore suggested for the postive-response genotypes to KNO3.Key words: fruit quality, KNO3, melon, sugar contentABSTRAKKalium (K) merupakan mineral yang dibutuhkan oleh tanaman yang berpengaruh terhadap kualitas buah dan sayur. Pada budidaya melon umumnya, sumber mineral K diperoleh dalam bentuk KNO3. Penelitian ini bertujuan mengidentifikasi pengaruh interaksi genotipe × perlakuan KNO3 (G × KNO3) terhadap peningkatan kualitas buah melon. Percobaan dilakukan pada bulan Agustus sampai Oktober 2016 di Kebun Percobaan IPB Tajur II, Bogor menggunakan rancangan petak terbagi (split plot design) dengan tiga ulangan. Petak utama merupakan perlakuan KNO3 dengan dua taraf, dan anak petak merupakan genotipe dengan delapan taraf, yang terdiri dari tujuh genotipe uji dan satu varietas pembanding (Eagle). Perlakuan KNO3 dilakukan setiap minggu mulai 7–49 HST dengan konsentrasi 5 g L-1 dan volume aplikasi ± 200 ml tanaman-1. Interaksi G × KNO3 berpengaruh nyata terhadap karakter kadar gula dan total asam tertitrasi (TAT). Genotipe P34 memiliki kadar gula dan TAT yang relatif tinggi. P25 merupakan genotipe yang menunjukkan respon positif berupa peningkatan kadar gula pada perlakuan KNO3, namun sebaliknya genotipe Eagle, P311, dan P34 justru menunjukkan penurunan kadar gula yang signifikan pada perlakuan KNO3. Karakter yang memiliki nilai heritabilitas (repeatabilitas) arti luas yang tergolong tinggi adalah umur berbunga jantan, umur berbunga hermaprodit, dan bobot buah, sedangkan yang heritabilitasnya tergolong sedang adalah umur panen, diameter buah, tebal daging buah, tebal kulit buah, dan kadar gula. Bobot buah berkorelasi positif dengan diameter buah, tebal daging buah, dan tebal kulit buah. Aplikasi pemupukan KNO3 secara praktis disarankan pada genotipe melon yang memiliki respon positif terhadap KNO3.Kata kunci: kandungan gula, KNO3, kualitas buah, melon

The use of saline water is one of the major challenges of agriculture, as it can cause nutritional imbalances and thus reduce crop yield. This study proposes to examine the efficiency of potassium nutrition as a salt stress-mitigating agent in melon grown in a protected environment. The experiment was laid out in a randomized-block design with ten treatments in a 2 × 4 factorial arrangement represented by two melon cultivars (McLaren and SV1044MF) and four nutrient solutions (S1 - standard nutrient solution, 2.5 dS m-1; S2 - nutrient solution salinized with NaCl, 5.0 dS m-1; S3 - nutrient solution salinized with NaCl + 50% K, 6.5 dS m-1; and S4 - nutrient solution salinized with NaCl + 100% K, 7.5 dS m-1). Yield (average fruit weight, production, fruit diameter, internal cavity, and pulp thickness), quality (pulp firmness, total sugars, soluble solids [SS], vitamin C, pH, titratable acidity [TA] and SS/TA ratio) and nutritional (K, Na and K/Na ratio) variables were evaluated. Plants fertigated with standard nutrient solution showed the highest values for fruit weight (1,190.6 g), production (2,381.3 g per plant), fruit diameter (13.6 cm) and pulp thickness (2.6 cm). Cultivar McLaren produced heavier fruits (931.4 g) with larger diameter (12.4 cm) and pulp thickness (2.4 cm). The addition of NaCl to nutrient solution induced a reduction in the yield variables but did not influence fruit quality. The addition of extra K to salinized nutrient solution did not mitigate the deleterious effect of salinity on the yield of melon.

Importance of fruits as valuable food resources, attention has been paid in recent years to study their physicochemical properties. Therefore, this investigation was undertaken to measure the physicochemical properties of the sweet orange genotype available in Bangladesh. A total of 8 genotypes including 3 released varieties (BAU Malta-1, BAU Malta-3, and BARI Malta-1) and 5 lines (CS Jain-001, CS Jain-002, CS Jain-003, CS Ram-001, and Variegated Malta) were included in this trial. Maximum average fruit weight (286.00 g), fruit size in terms of length (92.00 mm), and diameter (82.00 mm), mesocarp thickness (10.00 mm), and width of epicarp equatorial area (76.00 mm) was recorded from CS Jain-001 while the maximum number of segment (28.00), the diameter of fruit axis (23.66 mm), juice content (41.44%), titratable acidity (0.99%) and TSS: TA (33.73) was recorded from BAU Malta-3. TSS and juice pH was recorded maximum of 10.21% and 4.48, respectively in BAU Malta-1. Sugar content was found to be as follows, reducing sugar was the maximum in CS Jain-001 (3.50 %) while the highest total sugar (4.68%) was recorded in BAU Malta-1. Variegated Malta produced the maximum (48.45 mg/100 ml juice) ascorbic acid while CS Jain-001 contained maximum (8.35 mg/100 ml juice) ß-carotene. Therefore, considering fruit quality, BAU Malta-3, BARI Malta-1 can be used as fresh fruit. However, considering the fruit size, CS Jain-001 and CS Jain-002 could be used as breeding material to develop a new sweet orange variety with higher yield potential.

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.

AbstractSugar content is one of the most important quality traits of tomato. Cell wall invertase promotes sucrose unloading in the fruit by maintaining a gradient of sucrose concentration between source leaves and fruits, while invertase inhibitor (INVINH) regulates this process. In this study, knock-out of cell wall INVINH in tomato (SlINVINH1) was performed by genome editing using, CRISPR/Cas9 and Target-AID technologies. Most of the genome-edited lines set higher soluble solid content (SSC) fruit than the original cultivar ‘Suzukoma’, while fruit weight was different among the genome-edited lines. From these genome-edited lines, three lines (193–3, 199–2, and 247–2), whose SSC was significantly higher than ‘Suzukoma’ and fruit weight were almost the same as the original cultivar, were selected. The fruit weight and overall plant growth of the two lines were comparable to those of the original cultivar. In contrast, the fructose and glucose contents in the mature fruits of the two lines were significantly higher than those of the original cultivar. The mature fruits of genome edited line 193–3 showed the highest sugar content, and the fructose and glucose contents were 29% and 36% higher than that of the original cultivar, respectively. Whole genome sequence data showed no off-target mutations in the genome-edited lines. Non-target metabolome analysis of mature fruits revealed that fructose was the highest loading factor in principal component analysis (PCA) between the genome-edited line and the original cultivar, and no unexpected metabolites appeared in the genome-edited line. In this study, we succeeded in producing tomato lines with high sugar content without a decrease in fruit weight and deterioration of plant growth by knock-out of SlINVINH1 using genome editing technology. This study showed that functional disruption of SlINVINH1 is an effective approach to produce tomato cultivars with high sugar content.

The climate change and growing production of crops increase the demand for the water and the efficient use of water in agriculture becomes more critical. This experiment presents the results of research in the orchard with different irrigation programs and fertigation on yield and quality parameters of the ’Gala‘ and ’Fuji‘ apple tree. Three irrigation programs were applied IR + F – full irrigation with fertigation; IR – full irrigation without fertigation; NON‑IR – non‑irrigation, only natural precipitations. There were no differences observed among these three irrigation programs for tree diameter, sugar content, starch content and fruits firmness (P < 0.05). Significant deficit of water was in program IR and NON‑IR, at the length of annual growth, where the reduction was from from 680 mm to 440 mm at the ‘GALA’ variety. Statistically important differences between the irrigation variants were found out at the variety ‘Fuji’, in parametres yield, fruit weight and fruit diameter. Between programs IR + F and NON‑IR was the difference of fruit weight 25.6 g (14.3 %) and of fruit diameter 4.5 mm (5.8 %).

The experiment was carried out to assess the suitability of different mulch materials in enhancing the growth and fruit yield of okro. Ten okro genotypes were evaluated in a split plot design with 3 replications. Three treatments of mulch (black plastic, grass, and no mulch) represented the main plots with the genotypes as the subplots. The result indicated significant (P<0.05) genotypic variability among the genotypes for all parameters except plant girth. However, genotype and mulch interaction was not significant. The genotype Sasilon had the tallest plants (82.6 cm) and the highest fruit yield under all mulch conditions while Koni had the widest fruits (34.1 mm) with TZ SMN 10-3 having the longest fruits (16.11 cm). Number of fruits per plant ranged from 30 to 11 with an average of 21. Mulching significantly (P<0.05) influenced all parameters except fruit width and mean fruit weight. Plastic mulched plots had the greatest heights while no mulching had the least. The highest average yield was obtained under plastic mulch (3.49 t/ha) which was 4.2% higher than grass (3.34 t/ha) and 11% higher than no mulch (3.11 t/ha). The study has shown that mulching with black plastic or grass ensures vigorous growth and improves the fruit yield of okro.

The aim of this study was to understand the flavor components of eating quality of several strawberry (Fragaria ×ananassa Duch.) genotypes grown in Florida over two harvest seasons. Five selections and one cultivar of the University of Florida Breeding program as well as two new cultivars from Australia (Rubygem and Sugarbaby) harvested on different dates from the same grower were evaluated by sensory evaluation. Festival, the main strawberry cultivar grown in Florida, had low ratings for flavor and sweetness in January and March. Selection FL 00-51 and ‘Rubygem’ had relatively high and consistent ratings for flavor and sweetness compared with the other selections. Genotypes with low flavor ratings were always judged as “not sweet enough” by the panelists, thus linking flavor to sweetness preference. Instrumental analysis confirmed that typically these selections had low soluble solids content (SSC) and/or high titratable acidity (TA), thus explaining their lack of sweetness. Volatile compounds that varied only quantitatively did not seem to influence the flavor rating except for ‘Sugarbaby’. This cultivar contained between seven and 40 times less total ester content than the other selections and was disliked by panelists despite its high sugar content and perceived sweetness. It was perceived as having an artificial peach- or blueberry-like flavor. A principal component analysis was performed with chemical parameters (SSC, TA, and volatile content) and selections over the two harvest seasons. Chemical composition was mainly influenced by harvest date, except for FL 00-51. This selection maintained high volatile content and SSC throughout the seasons, explaining consistently high flavor ratings.

<p>ABSTRACT<br />Breeding of melon requires the availability of genetic diversity and extensive evaluations of the genetic materials. Evaluations on fruit quality and yield potential are among the important steps in melon breeding. This research was aimed at studying the genetic diversity of 17 melon genotypes based on fruit traits and identifying the potential genotypes to be used as genetic materials in melon breeding programs. The research was conducted from August to October 2015 at the IPB Experimental Station Tajur II, South Bogor, 250 m above sea level. The experiment was arranged in a single factor of randomized complete block design with four replicates. Results of the research showed that genotype effects were significant for all observed traits except for days to hermaphrodite flowering. Traits having broad sense heritability estimates greater than 50% were days to male flowering, days to harvest, fruit length, fruit diameter, flesh thickness, fruit rind thickness, fruit weight, and sugar contant. P21 and P19 genotypes were potential for fruit weight and sugar content, while P2 was potential for fruit weight and P12 for sugar content only. Fruit weight showed significant positive correlations with fruit length, fruit diameter, flesh thickness, and fruit rind thickness. Clustering based on morphological traits generally separated reticulatus and inodorus genotypes into different groups.<br />Key words: correlation, heritability, simultaneous selection</p><p>ABSTRAK<br />Pemuliaan tanaman melon memerlukan ketersediaan keragaman genetik dan evaluasi yang ekstesif pada materi genetik yang digunakan.
