Karakteristike plodova paprika poreklom iz slobodne oplodnje
Fruit traits of pepper genotypes originating from open pollination
Projekat: Stvaranje sorata i hibrida povrća za gajenje na otvorenom polju i u zaštićenom prostoru (MPNTR - 31030)
Sažetak
Paprika je jedna od značajnijih povrtarskih vrsta u Srbiji. U pojedinim regionima naše zemlje potrošači su navikli da konzumiraju plodove različitog oblika, veličine i boje. Cilj ovog rada je da se ispitaju 4 genotipa paprike (355, 356, 357 i 358) kraćih plodova poreklom iz slobodne oplodnje, poredeći ih sa ishodnom majčinskom linijom 354 dužih plodova. Na plodovima iz druge berbe izmerena su sledeća svojstva: dužina, širina i masa ploda, broj komora, debljina perikarpa, sadržaj suve materije i prinos plodova po biljci. Indeks ploda je izračunat na osnovu odnosa dužine i širine ploda. Podaci su obrađeni u programu Statistica 12, metodom analize varijanse, koristeći Dankanov višestruki test intervala na nivou značajnosti 0,05. Između ispitivanih genotipova nije bilo značajnih razliku u prinosu plodova po biljci. Na osnovu izmerenih svojstava, genotip 357 će biti korišten za dalji selekcioni rad zbog veće mase ploda, a genotip 358 zbog debljeg perikarpa.
Abstract
In different regions of Serbia people consume pepper fruits with various shapes, sizes and colors. In southern Serbia consumers prefer longer fruits, while in the northern part shorter fruits are more preferred. The aim of this paper was to evaluate four pepper genotypes (355, 356, 357, and 358) with shorter fruits originating from open pollination. These genotypes were compared with the parental line 354 with longer fruits. The fruits were harvested in technological maturity. Fruit (length, width, weight, and index), locule number, pericarp thickness, total soluble solids and fruit yield per plant were evaluated. The line 354 had the longest fruits (14.46 cm). Genotype 358 had the highest pericarp thickness (5.8 mm), while the genotype 357 had the highest fruit weight (105 g). Based on the evaluated traits, genotype 357 will be used for further selection because of higher fruit weight, and genotype 358 because of a thicker pericarp.
