Our expedition has identified different location t of Kosovo where we were collected a samples at altitudes from 545 till 748 m.a.s.l. The aim of the present investigation was carried out to study morphological diversity, protein and lipids content. Protein content (PC) was determined by Kjeldahl method. Lipids were determined by extraction using Soxhlet apparatus and diethyl ether was used as extraction solvent. Pumpkin populations show great diversity for quality traits. The greater part of variance was accounted for Protein Content (PC) and Lipid Content (LC). The estimation overall value μ in seed for PC and LC were 14.59%, and 32.99% respectively. The genetic diversity studies of the investigated of C. pepo showed significant genetic variation on chemical parameters, which could be largely due to that they were of different origins. This evaluation of traits variability can assist breeders to identify populations with desirable characteristics for inclusion in variety breeding programs.展开更多

The design of the experiment was based on split plot methods. From the total samples collected, were selected 16 mostly widespread samples of natural populations of origano (Origanum vulgare L. sp. vulgare and sp. hirtum). Essential oil isolation from oregano was performed by hydro distillation. Identification of the components was made by comparing mass spectra of components in essential oils with those from Nist, Wiley and Adams mass spectra libraries. The results show that the total oil content varies from 3.45% to 0.1%. The populations of Oregano in the part of southern Albania have a higher amount of etheric oil compared with those of the North part. The higher content of carvacrol in 55.63%, of the samples was determined in sites of the southern part of Albania, while in the other two investigated area central and north part it was 55.63% and 48.49% respectively. The same indicators were realised also for content of linalool and thymol, while North area has sites with high content of caryophyllen-oxide and β-pinen 3. But, in all sites, the oils of thymol and carvacrolit were dominant.展开更多
