Heirloom tomato cultivars and local populations as sources of genetic variability for breeding
Korišćenje starih sorti i lokalnih populacija paradajza kao izvora genetičke varijabilnosti u oplemenjivanju
Abstract
Five local tomato populations and fourteen heirloom cultivars were analyzed in this study. The analyzed genotypes represent a part of tomato collection of Institute of Field and Vegetable Crops in Novi Sad. The following fruit and plant traits were analyzed: growth type, fruit color, fruit shape index, fruit weight, number of locules and dry matter content. Cluster analysis was performed so as to group the analyzed genotypes by homology and divergence. The aim of this article was to determine the importance of heirloom cultivars and local populations as sources of genetic variability in tomato breeding process.
Sažetak
U ovom istraživanju je analizirano 5 lokalnih populacija i 14 starih sorti paradajza. Ispitivani genotipovi predstavljaju deo kolekcije paradajza Instituta za ratarstvo i povrtarstvo u Novom Sadu. Analizirane su sledeće osobine biljke i ploda: tip rasta, boja ploda, indeks oblika ploda, masa ploda, broj komora i sadržaj suve materije u plodu. Primenjena je analiza grupisanja (klaster analiza) u cilju grupisanja ispitivanih genotipova na osnovu sličnosti i razlika za ispitivana svojstva. Cilj rada je ispitivanje značaja starih sorti i lokalnih populacija kao izvora genetičke varijabilnosti u oplemenjivanju paradajza.
