Adaptability and stability of NS sugar beet varieties grown in different agroecological conditions

Abstract

In 2001 and 2002 seven sugar beet varieties with different level of rhizomania resistance were tested on five locations, for root yield, sugar content and yield stability. Analyzed traits depended on agroecological conditions and varied from 44.96 t/ha to 95.00 t/ha for root yield, 11.30% to 16.56% for sugar content and 5.08 t/ha to 13.54 t/ha for sugar content. Varieties Mara and Sara had the highest sugar content. High general adaptability for root and recoverable sucrose yield had variety Drena, while variety Sara had significantly higher stability for those traits.

Tokom 2001. i 2002. godine na 5 lokaliteta je ispitivano 7 sorti šećerne repe različitog nivoa tolerantnosti prema rizomaniji. Utvrđen je prinos korena sadržaj šećera i prinos šećera i po modelu Eberhart i Russell (1966) izračunata stabilnosti sorti. U zavisnosti od faktora spoljne sredine prinos korena je varirao od 44,96 t/ha do 95,00 t/ha, sadržaj šećera od 11,30% do 16,56% i prinos polarizacionog šećera od 5,08 t/ha do 13,54 t/ha. U sadržaju šećera prednost su pokazale sorte Mara i Lara. Visoku opštu adaptabilnost za prinos korena i prinos šećera pokazala je sorta Drena, dok je sorta Sara pokazala natprosečnu stabilnost za ova svojstva.
