Productivity of NS sugar beet hybrid varities resistant to rhizomania (BNYVV) infield trials

Abstract

In the paper are presented results of three year long field testing on four locations. Four hybrid varieties were tested: three varieties, Sara, Lara and Drena, accepted by Plant variety comission, Ministry of agriculture and water management, Republic of Serbia and one experimental hybrid. Three most important quantitative traits were tested: root yield, sugar content and sugar yield, who were than compared with standard varieties. It could be observed that varieties did not significantly differ among themselves, which was to be expected since all three of them are resistant to rhizomania. Regularity in trials were noted but not statistically proved that variety Lara has high sugar content, Sara is normal type variety, and Drena has high root yield.

U radu su prikazani rezultati trogodišnjih ispitivanja šećerne repe na većem broju lokaliteta. Ispitivane su hibridne sorte šećerne repe otporne prema Rizomaniji koje su priznate od strane Zavoda za biljne i životinjske genetičke resurse, Komisije za priznavanje sorti pod nazivom Sara, Lara i Drena i jedan eksperimentalni hibrid koji se nalazi u ispitivanju. Ispitivane su tri najznačajnije kvantitativne osobine: prinos korena sadržaj šećera i prinos kristalnog šećera i upoređivanje sa standardnim sortama. Između tri priznate sorte nisu ustanovljene značajne razlike, jer se radi o sortama otpornim prema Rizomaniji. Pravilnost koja je u ogledima uočena ali nije statistički potvrđena je da sorta Lara ima naglašen sadržaj šećera, Sara je normalnog tipa a Drena ima naglašen prinos korena.
