  • Fifty-five sweet pepper (Capsicum annuum L.) germplasm from the Rural Development Administration (RDA) were analyzed for their fruit yield and fruit quality characters, including fruit weight, fruit size, pericarp thickness, total soluble content, fruit lobe, fruit shape, fruit surface and fruit color. Fruit yield per plot ranged from 200 g to 8150 g (average, 1884 g). Fruit fresh-weight per fruit ranged from 27.3 g to 200.0 g with an average of 97.2 g. Fruit length varied from 4.0 cm to 16.2 cm (average, 9.6 cm). Fruit length-to-width ratio ranged from 0.6 to 3.0 with an average 1.7. The fruit pericarp thickness ranged from 1.8 mm to 10.7 mm (average, 4.8 mm). Total soluble content was the highest ($8.5^{\circ}Brix$) in K156286 and the lowest ($5.3^{\circ}Brix$) in K156208 with the average value $6.7^{\circ}Brix$. Fruit lobes numbers varied from 2 to 4. Blocky, triangular, elongated, rectangular and round fruit shape identified among the sweet pepper accessions. Fruit surface varied from smooth to wrinkle and fruit color also varied. The presence of variability in fruit yield and quality traits within the sweet pepper genotypes can be utilized to develop high yielding sweet pepper variety with better fruit quality characters.

  • We analyzed the correlation among fruit bearing branch (FBB) and shoot and fruit characteristics in order to select the length of FBB suitable for producing high-quality fruits of 'Soomee', a peach tree developed in Korea. The length and diameter of FBB were 26.1 cm and 6.1 mm, respectively, shoot and leaf number per FBB were 3.2 and 38.6, respectively. Of these, the coefficient of variation was very high in the shoots and leaf number. The average weight and soluble solid content (SSC) of fruit were 298.6 g and 12.2 Brix, respectively, and coefficient of variation of the fruit weight was 18.0 %, which was higher than that of SSC. As the FBB of 10-20 cm and 20-30 cm length per tree were 27.1 % and 25.4 %, respectively, the sum of short and middle FBB frequency per tree was more than 50 %. Fruits of 250-350 g and 11.0-13.0 Brix per tree were distributed in 68.6 % and 74.0 %, respectively. As a result of correlation analysis, fruit weight and shoot number were affected by the length of FBB. In particular, length of FBB showed the relation of fruit weight with $y=-0.0482x^2+2.4512x+277.36$. As a result, the length of FBB that can maximize fruit weight was analyzed as 25.4 cm. Therefore, in the filed, the suitable FBB for producing 'Soomee' peach is estimated to be about 20-30 cm.

  • Schisandra chinensis is a fruit which is called Omija in South Korea. The Korean word Omija means "five flavors" (sweet, spicy, sour, bitter, and salty). The aim of his study was to investigate the correlation between growth characteristics and lignans (gomisin A, gomisin N, schisandrin) contents of Schisandra chinensis. The method for determining lignans was validated by measuring the linearity, limit of detection (LOD), limit of quantification (LOQ), precision and accuracy using UPLC-UV. Growth characteristics of S. chinensis such as number of fruits per fruit bunch, length of fruit bunch, width of fruit bunch, fresh weight of fruit bunch, length of fruit, width of fruit, fresh weight of fruit, fresh weight of 30 fruits, and sugar contents of fruit were measured. From the results of correlation analysis, it was found that the contents of lignans showed a significantly negative correlation with fresh weight and sugar contents of fruit. These results will be used to study for quality control of S. chinensis fruit.

  • Watermelons, Citrullus species(Cucurbitaceae), are native to Africa and have been cultivated since ancient times. T he fruit flesh of wild watermelon is watery, but typically hard-textured, pale-colored and bland or bitter. The familiar sweet dessert watermelons, C. lanatus, featuring non-bitter, tender, well colored flesh, have a narrow genetic base, suggesting that they are originated from a series of selection events in a single ancestral population. In this study, considered as sweet dissert watermelon, genetic resources, C. lanatus, comprising of traditional cultivars and local accessions were collected from 18 different countries in four continents. A total of 60 accessions were characterized morphologically according to RDA genebank descriptors combined with Japan and China, list for 11 qualitative characteristics, leaf length, leaf width, petiole length, petiole diameter-source, stalk end length, stalk diameter, fruit length, fruit diameter, rind thickness, flesh sugar content($^{\circ}brix$), fruit weight-sink, and 6 sink related characters, leaf margin incision-source, fruit shape, fruit skin ground color, fruit skin stain color, fruit skin stain pattern and flesh color-sink, were also investigated. Even though the relatedness between some morphological traits and fruit weight or fruit sweetness showed no significance, the accessions investigated have a great deal of variation for most of the morphological traits. Additionally, the accessions which showed good performance in flesh color and fruit shape (IT271048) and high sugar content of flesh (IT274119, IT290118) above 14brix, were investigated in this experiment. The accessions, which have the information on specific traits including the selected accessions could be introduced, distributed and investigated for further use.

  • A field experiment was conducted to examine the fruit quality characters in second generation ($F_2$) hybrid cultivar and to compare the fruit characters with original $F_1$ hybrid cultivar of minipaprika (yellow and orange type) at the Research Farm, Hwacheon in July, 2010. Fruit characters varied within $F_2$ population of each minipaprika type. In minipaprika yellow, fruit weight varied from 12.2 g to 50.8 g (average 28.5 g) and fruit length/width varied from 1.4 to 2.8 (average, 2.0). Pericarp thickness ranged from 1.8 mm to 4.1 mm (average, 2.9 mm). Total soluble solid (TSS) varied from $6.2^{\circ}Brix$ to $13.5^{\circ}Brix$ with an average of $8.7^{\circ}Brix$. Fruit volume varied from 10.3 cc to 46.7 cc with an average of 24.4 cc. In minipaprika orange type, fruit weight ranged from 19.7 g to 42.4 g (average, 29.0 g) and fruit length/width varied from 1.5 to 2.6 (average, 2.0). Pericarp thickness varied from 2.1 mm to 4.1 mm with an average of 3.0 mm. TSS varied from $5.0^{\circ}Brix$ to $12.2^{\circ}Brix$ (average, $7.9^{\circ}Brix$) and average fruit volume was 24.6 cc ranging from 10.7 cc to 35.0 cc. The average fruit quality characters in $F_2$ population in both yellow and orange minipaprika did not differ from their $F_1$ hybrid parent and $F_2$ seed can be an additional way to supply high yielding hybrid cultivars at lower cost to the minipaprika growers.

  • Flower and fruit characteristics, in 'Hongro' and 'Galaxy Gala' apples, were investigated by bearing branch lengths and flower bud position such as blow 5 cm, $10{\sim}15cm$ and above 20 cm length with terminal bud, and above 20 cm length with axillary bud for investigation on possibility of alternative use of long bearing branch and axillary bud in case of die-back of spur flower bud. In flowering characteristics by flower bud position in the above 20 cm length, the terminal bud was later and was short in flowering period, and also was little in number of flower per bud. Fruit weight, number of seeds, and sugar-acid ratio, in characteristics of ripening fruit, were more the blow 5 cm and $10{\sim}15cm$ length, but soluble solid and malic acid contents was the opposite tendency. In fruit characteristics by flower bud position in the above 20 cm length, the terminal bud had high tendency expected far number of seed in 'Hongro' and Hunter a value of 'Galaxy Gala' apple but had not significant difference. Correlation between fruit weight and number of seed was high. As the results, value of alternative use of long bearing branch in apples had a little expected for fruit weight, especially was more 'Galaxy Gala' and the axillary bud.

  • This study was carried out to evaluate growth, morphological characteristics, and sugar content among fifty six blackberry (Rubus fructicosus) genotypes derived from gamma-ray treatment (fifty two lines), MNU treatments (three lines), and cross breed R. fructicosus${\times}$R. parvifolius(one line). While 56 genotypes had similar stem diameter with origin variety, the most of mutants showed reduced leaf size. Also, they showed a wide range of variation in fruit size and one hundred fruit weight compared with origin variety. In fruit size and sugar content, two mutant lines showed large fruit sizes and ten mutant lines showed 20% higher sugar content than the original variety. In the correlation analysis, positive relationships were determined between sugar content and stem diameter, fruit length, leaf wide and fruit length/fruit wide ratio. However, leaf length/leaf wide ratio showed a negative correlation with sugar content. The results will be used as fundamental data for Rubus fructicosus breeding program.
