dc.description.abstractThe research was conducted in order to determine yield related characters which are more effective as selection criteria than yield itself. Three spring canola (Brassica napus L.) genotypes have been investigated for plant height, number of primary branches (including the main raceme), number of pods per plant, pod length, number of seeds per pod, seed weight per pod and 1000 seed weight and their correlations with seed yield per plant. Seed yield had highest correlation with number of pods per plant (r= 0.935 and r= 0.973 in Skopje and Strumica, respectively), followed by seed weight per pod (r= 0.693 and r= 0.729) and 1000 seed weight (r= 0.627 and r= 0.680). Path coefficient analysis was used to identify the direct and indirect effect of studied characters on seed yield. Number of pods per plant (p=0.759 and p=0.877 for Skopje and Strumica, respectively) and seed weight per pod (p=0.216 and p=0.225) had the highest direct effect on seed yield in both locations followed by 1000 seed weight (p=0.056 and p=0.010). The coefficient of determination (R2) was 0.943.en
dc.description.abstractIstraživanje je sprovedeno sa ciljem da se determinšu komponente prinosa koje mogu pretstavljati efektivniji kriterijum za selekciju nego prinos "per se". Kod tri jara genotipa uljane repice (Brassica napus L.) su bila ispitivana svojstva: visina biljke, broj primarnih grana (uključujući i centralnu), broj ljuski po biljci, dužina ljuski, broj semena po ljusci, masa semena po ljusci i masa 1000 semena, kao i njihove korelacije sa prinosom semena po biljci. Broj ljuski po biljci je imao najveću vrednost koeficijenta korelacije sa prinosom po biljci (r= 0.935 i r= 0.973 u Skoplju i Strumici). Nešto manju vrednost je imao koeficijent korelacije za masu semena po ljusci (r= 0.693 i r= 0.729) i masa 1000 semena (r= 0.627 i r= 0.680). Analiza path koeficijenta je korišćena za razdvajanje direktnih i indirektnih uticaja ispitivanih svojstava na prinos semena. Broj ljuski po biljci (p=0.759 i p=0.877 za Skoplje i Strumicu) i masa semena po ljusci (p=0.216 i p=0.225) su imale najveći direktni efekat na prinos semena po biljci u obe lokacije. Nešto manja vrednost ovog pokazatelja izračunata je za masu 1000 semena (p=0.056 i p=0.010). Koeficijent determinacije (R2) je iznosio 0.94.sr
