“…The maximum value (0.69) of Shannon's Information Index (I) was exhibited by total 10 primers, while it was observed minimum (0.41) in two primers viz, BoGMS1460 and BoSF1167. In our study, mean value of 'I' was recorded as 0.62, which is greater than as observed earlier by Paulauskas et al (2013) in Brassica napus (0.12). The expected heterozygosity (0.45) had higher mean values than observed heterozygosity (0.32).…”

A comprehensive study on characterization and genetic diversity analysis was carried out in 16 'Ogura'-based 'CMS' lines of cabbage using 14 agro-morphological traits and 29 SSR markers. Agro-morphological characterization depicted considerable variations for different horticultural traits studied. The genotype, ZHA-2, performed better for most of the economically important quantitative traits. Further, gross head weight (0.76), head length (0.60) and head width (0.83) revealed significant positive correlation with net head weight. Dendrogram based on 10 quantitative traits exhibited considerable diversity among different CMS lines and principle component analysis (PCA) indicated that net and gross head weight, and head length and width are the main components of divergence between 16 CMS lines of cabbage. In molecular study, a total of 58 alleles were amplified by 29 SSR primers, averaging to 2.0 alleles in each locus. High mean values of Shannon's Information index (0.62), expected (0.45) and observed (0.32) heterozygosity and polymorphic information content (0.35) depicted substantial polymorphism. Dendrogram based on Jaccard's similarity coefficient constructed two major groups and eight sub-groups, which revealed substantial diversity among different CMS lines. In overall, based on agro-morphological and molecular studies genotype RRMA, ZHA-2 and RCA were found most divergent. Hence, they have immense potential in future breeding programs for the high-yielding hybrid development in cabbage.

“…For erucic acid content, only moderate association was found with UBC 137_750. This is in agreement with the results of other authors who found no association between the phenotypic and morphological traits and the RAPD markers (BURLACU et al, 2011;FAHMI et al, 2012;PAULAUSKAS et al, 2013).

“…In addition to the already narrowed genetic variability, initially caused by the bottleneck, further impoverishment of tomato genetic resources and loss of desirable genes is inevitable. Plant genetic diversity is a very important prerequisite to cope with climate changes and withstand an attack of diseases and pests (Paulauskas et al, 2013). Reduction of genetic diversity leads to the permanent disappearance of many genes from the genetic pool, and loss of numerous traditional varieties.…”

Tomato is one of the most important species belonging to the Solanaceae family. Focusing on the importance of tomato in human nutrition and the problem of narrowed genetic variability, the aim of the study was to assess morphological and chemical diversity in IFVCNS germplasm collection. Twenty genotypes were analysed for the morphological and chemical fruit traits: average mass (g), length (cm), diameter (cm), pericarp thickness (mm), locules number, moisture content (%), total soluble solids (°Brix), ash content (%), total acidity (%) and pH value. Selected plant material for analysis included: landraces, traditional varieties, breeding lines and commercial varieties. Differences among tomato genotypes in all fruit traits were determined. Fruit mass and locules number had the highest coefficient of variation. The least differences between genotypes were observed in the fruit moisture content. Four principal components accounted for 90.6% of total variance or 36.5%, 24.2%, 19.8% and 10.1%, respectively. Along the axis of the first main component, genotypes were classified into three groups. The first component was defined by fruit length, diameter and mass. The second component was correlated with pericarp thickness and locules number, and the third with moisture content, ash content and total soluble solids. Based on the cluster analysis, genotypes were classified into three groups which were in agreement with the PCA groups. Hybridization between genotypes from different groups was proposed in order to create new hybrids and varieties and to increase tomato germplasm diversity. By crossing those genotypes, improved recombinations in morphological and chemical traits can be expected.
