Issue Date: | 1-Jan-2014 | Journal: | Genetika | Abstract: | The aim of this study is collecting and preserving of unique Cucurbita pepo germplasm in Serbia. This study also describes the intraspecific variation of C. pepo within twenty germplasm accessions. Conservation work aimed to develop a representative core collection of C. pepo germplasm, to guide future studies and breeding of its ornamental use. A wide range of C. pepo germplasm was collected from diferent parts of the world. Nineteen variables were recorded in 20 varieties to determine the overall degree of polymorphism and to detect similarities among them. Qualitative traits of fruit such is shape, color and texture, showed immense variation. Coefficient of variation were highest for fruit length, fruit weight and number of fruits per plant (CV=56.69-161.32%), while they were the lowest for leaf length (CV=20.65%). Morphological characterization is need to facilitate the use of C. pepo varieties in breeding work. Based on the PCA results, 20 accessions of squash are separate in five groups. Those groups are unique in qualitative and quantitative traits. Knowledge of genetic divergence among varieties is essential for breeding. | URI: | https://open.uns.ac.rs/handle/123456789/7731 | ISSN: | 05340012 | DOI: | 10.2298/GENSR1401199M |
