Germplasm Accessions

The study involved characterization of Jackfruit accessions with obloid (round) versus ellipsoid fruit shape. The morphological characterization was based on tree, fruit and seed descriptors. The Jackfruit accessions exhibited wide range of differences. The dominant tree growth habit was erect type, with medium to low branching density and branching pattern was irregular in most of the trees. With respect to fruit rind weight, it was more than fifty to sixty per cent in accessions with obloid fruit, than ellipsoid fruits. The rind weight ranged from thirty to forty per cent of the total fruit weight. Based on fruit and flake quality characters, the accessions such as Allilugatta 5, Kumaraswamy, Manipur Parmesh and Swarna in obloid fruits and Ashoka Red, Ashoka Yellow, Byrachandra, Janagere and NSP in ellipsoid fruits have been identified for commercial purpose. Among ten RAPD primers screened, two primers showed higher PIC value (0.24) viz., OPA 4 and OPAH 4. Similarly among ten ISSR markers screened, ISSR - 868 (0.31) showed higher PIC value. These can be used effectively to probe the genetic variations among the Jackfruit accessions.

Morphological characterization of genotypes is fundamental in providing information on their genetic status to guide on their conservation and improvement. The objective of this study was to determine agro-morphological diversity within horned melon in Kenya. The study was carried out in two seasons at the University of Embu in Kenya. The study characterized 19 horned melon accessions collected from different agro-ecological zones in Eastern, Central and Western regions in Kenya. The experiment was laid out in a randomized complete block design with three replications. Morphological characterization of the accessions was based on melon descriptors from International Plant Genetic Resources Institute (IPGRI) with slight modifications. Significant differences were observed in all the quantitative traits except the number of branches and main vine length. However, qualitative variations were only observed in fruit shape, rind colour and seed shape. Principle Component Analysis (PCA) showed that fruit weight, main vine length and days to maturity had the highest contribution to the observed diversity. Cluster analysis separated the accessions into seven groups with between classes diversity of 79.20% and within classes diversity of 20.80%. The diversity observed can be exploited by plant breeders for genetic improvement of the crop.

The red dragon fruit Selenicereus undatus is a native fruit from the Americas. Its growing appeal in the international market as an exotic fruit highlights the relevance of the crop for the local economies. In Colombia, the high diversity within the genus and species makes it difficult to have reliable materials for propagation as cultivars. This agronomic challenge requires more studies of the distribution and real diversity within the genus Selenicereus sp. Due to the information aforementioned, the fruit is harvested in small localities as an extraction production system. This project aimed to morphologically characterize the working collection of red dragon fruit under growing conditions in the Municipality of San Jerónimo. It contained 30 accessions from the departments of Antioquia, Córdoba, and Valle del Cauca. Twenty-one characters of cladode, flower, and fruit were quantified to assess the diversity, and a restricted cluster analysis was performed to understand the morphological richness of the materials. As a result, it was observed differences in terms of stems, such as distance between areolas and width of cladode. This was also observed in flowers, in which their total length, the width of petals, the presence of trichomes, the color of calyx and petals, and the color of the stigma were different. Also, differences were recorded in the fruit. Characteristics such as weight and color of its skin were assessed, resulting in fruit size medium to small. Regarding other properties, total soluble solids varied between 11.2 to 15.6 °Brix. 55% of the fruits have measurements that fit market requirements. Finally, three accessions match the requirements of weight and °Brix, to be used as possible genotypes by commercial growers; however, studies about agronomic management strategies that favor an increase in fruit weight must be done.

The research was conducted for the assessment of genetic diversity using both morphological and random amplified polymorphic DNA (RAPD) analysis of twelve guava (Psidium guajava L.) varieties growing in Bangladesh. Morphological characterization of guava varieties showed a wide range of variation. The highest variability was observed between Poly and Jelly varieties.Polymerase chain reaction with 5 arbitrary 10-mer and 3 arbitrary 12- mer RAPD primers produced a total of 50 bands of which 75.23 percent were polymorphic. The highest percentage of polymorphic loci (100%) was observed for primer A and the lowest (50%) for A03 primer. The UPGMA dendrogram revealed the segregation pattern and the difference of evolutionary changes. Guava varieties were separated into two main groups, one of them was made up of Chineese, Jelly, Kazi, Apple, L-49, Local-2 and Local-3. The other one was made up of Local-1, Poly, Kashi, Thai and Bombay. The highest genetic distance between Apple and Kazi peyara indicate that these varieties might be interesting in breeding programme for improving trait of interest. This scientific information could be used for further improvement of guava. Jahangirnagar University J. Biol. Sci. 7(2): 89-98, 2018 (December)

The mangabeira (Hancornia speciosa G.) is a native Brazilian species in the process of domestication. It has several potential uses. In recent years the populations of mangabeira have become fragmented and, to conserve their genetic resources, Embrapa Tabuleiros Costeiros has, since 2006, maintained a Mangaba Genebank, which currently has 299 individuals distributed across 27 accessions. In one of these accessions (CP), first fruiting was observed to occur at 13 months, indicating precocity. The current project was developed with the intention of morphologically characterizing the CP accessions and evaluating the extent of genetic diversity between genotypes, based on genetic markers associated with fruiting precocity. Morphological variation in crown and leaf shape, growth habit, total height, stem diameter and canopy height were investigated. For molecular characterization, 18 CP accession genotypes were used, all from Sergipe State, Brazil, and 11 ISSR markers were studied that generated 62 fragments with 91.4% polymorphism. The fruits have physical and chemical characteristics suitable for in natura consumption and also for processing. UPGMA dendrogram analysis showed the genotypes CP2 and CP6 to be most similar and CP10 the most divergent within the CP accessions. The results showed the existence of polymorphism, and genetic divergence among genotypes, thus reinforcing the importance of constant germplasm characterization, which guarantees information on gene sources for future use, while providing information concerning potential parents that can be used in breeding programs as well as the identification of duplicates.

The objective of the present paper was to characterize some avocado fruit varieties to increase the information pool for this fruit. Twelve avocado varieties of medium oil content (8.09-11.12%) from a Venezuelan orchard: Wilson Popenoe, Figueroa 1, Waldin, Puebla, Schaff, Celia, Araira FM, Adolfo, Esencia de la Vega, Lawhon, Winslowson, and Lujo were characterized for pulp oil and moisture; weight (whole fruit, seed, pulp, and peel); length, width, and fruit shape; peel characteristics (roughness, color and hand peeling); and ripeness time. Differences in oil content, moisture content and fruit weight were found when compared with results reported by other authors. The variety Puebla was the lightest (107 g) and the smallest (7.90 x 4.62 cm), while Wilson Popenoe presented the highest pulp proportion (82%). Most of the varieties were ovate, with rough green peel and easy to hand peel. Peak ripeness of some varieties was at 3-12 days. Potential yields of two varieties were higher that the Venezuelan average.

Characterization of local germplasm is an effective way to identify elite breeding material and develop improved varieties. This study was aimed to assess 52 tomato accessions comprised of local varieties (28), landraces (8), breeding lines (14), and wild relatives (2) and its characterization for 30 morphological/agronomic, four fruit quality, and Tomato Mosaic Virus (ToMV) resistance traits. Morphological, quality, and ToMV traits were evaluated using phenotyping, biochemical assays, and molecular markers, respectively. Fruit shape and size showed appreciable variation with fruits varied from rounded to heart shape and small to big size. Significant variation was observed for fruit weight (1.6g to 564.8g), fruits per plant (6.0 to 174.7), productivity (130.5g to 5146.5g), soluble solids (4.1% to 8.4%), vitamin C (9.5 mg/100g to 46.4 mg/100g), antioxidant activity (2.5 μmol Fe2+/g FW to 9.6 μmol Fe2+/g FW), and total polyphenols (23.9 GAE/100g FW to 124.2 GAE/100g FW). All accessions were phenotypically screened for the virus resistance in the growth chamber and CAPS molecular markers were used to identify accessions with ToMV Tm-22 resistant alleles and accessions LYC-13, LYC-15, LYC-17, LYC-26, and LYC-52 were identified as resistant. Multivariate analysis of morphological and quality traits showed that 35 principal components (PCs) contributed to the total variation and the first two and twelve PCs explained 47.2% and 90% variation, respectively. The evaluated tomato collection appears to have breeding potential and around 20% accessions of the collection (LYC-6, LYC 17-18, LYC 26-31, LYC 33) are promising genetic resources for variety development that are enriched with enhanced fruit quality and high yield.
