dc.description.abstractVarijabilnost biljnih genetičkih resursa pruža mogućnost oplemenjivačima da razviju nove i poboljšane sorte izmenjenog kvaliteta i otporne na bolesti i nepovoljne uslove sredine. Oplemenjivanje uljanih biljnih vrsta u Institutu za ratarstvo i povrtarstvo (IFVCNS) ima uspešnu pedesetogodišnju tradiciju čiji je rezultat kolekcija od 7000 linija gajenog suncokreta, kao i kolecija divljih srodnika suncokreta i značajne kolekcije genetičkih resursa uljane repice, bundeva i još 24 alternativne uljane biljne vrste. Poznavanje genetske konstitucije i odnosa između genotipova unutar kolekcije je od suštinskog značaja za efikasno korišćenje germplazme. U studijama varijabilnosti, molekularni markeri imaju prednost u odnosu na druge tehnike jer su nezavisni od uslova životne sredine i faze razvoja biljke, te se sve više se koriste za analizu genetičke varijabilnosti. U skladu sa tim, varijabilnost IFVCNS kolekcija divljeg i gajenog suncokreta, uljane repice, bundeve i šafranjike je analizirana upotrebom različitih molekularnih markera. Molekularne analize su pokazale postojanje velike inter- i intraspecies varijabilnosti u testiranim populacijama. U većini slučajeva, dobijeno grupisanje genotipova je odražavalo filogenetske odnose. Dobijeni su različiti rezultati u pogledu geografskog porekla, odnosno nije utvrđena korelacija između grupisanja i geografskog porekla testiranih genotipova bundeve, dok su se kod uljane repice genotipovi grupisali prema geografskom poreklu. Utvđena je i potvđena povezanost pojedinih markera i otpornosti na bolesti, izmenjenog kvaliteta, kao i pojedinih kvantitativnih svojstava. Pomoću do sada korišćenih molekularnih analiza nije pronađena čvrsta korelacija za morfološka i svojstva uslovljena većim brojem gena. Dalja istraživanja će se fokusirati na asocijativno mapiranje i dalje pronalaženje veza između molekularnih markera i agronomski važnih osobina.sr
dc.description.abstractDiversity in plant genetic resources provides an opportunity for plant breeders to develop new and improved cultivars with altered quality traits, resistant to diseases and unfavourable environment. Oil crops breeding at Institute of Field and Vegetable Crops (IFVCNS) has a successful 50-year long tradition that resulted in collection of 7000 sunflower inbred lines, as well as collection of wild sunflowers and substantial collections of genetic resources of rapeseed, pumpkins and 24 minor oil crops. The knowledge of genetic constitution and relationships among genotypes within the collection is essential for effective utilization of germplasm. In variability studies, molecular markers have advantages over other techniques as they are independent of the environment and plant growth stage and they have been increasingly employed for genetic diversity analyses. Hence, variability of IFVCNS collections of wild and cultivated sunflower, rapeseed, pumpkins and safflower were accessed with the use of different molecular markers. Molecular analyses revealed great inter- and intra-species variability of tested accessions. In most cases, molecular clustering reflected phylogenetic relationships. Contrasting results were obtained regarding geographic origin, as no correlation was found between clustering and geographical origin of tested pumpkin genotypes, while in rapeseed tested genotypes clustered according to geographic origin. Relationship between certain markers and disease resistance, altered quality, as well as certain quantitative properties was established and verified. No solid correlations were found for morphological and polygenic traits by molecular studies conducted so far. Further studies will focus on associative mapping studies and finding links between molecular markers and agronomically important traits. Key words: sunflower, rapeseed, pumpkins, minor oil crops, molecular markerssr
