Dunav and Vrbas: New NS varieties of spring oat

Abstract

Oat breeding program has been revived at the Institute of Field and Vegetable Crops Novi Sad after almost fifty years. From this program the following varieties were released: in 2001 spring naked oat Novosadski golozrni, in 2008 spring chaffy oat Dunav and in 2009 spring chaffy oat Vrbas. Variety Dunav has also been released in Bosnia and Herzegovina but renamed as Jelena. Dunav and Vrbas are hexaploid varieties of species Avena sativa. In two-year six-location trials of the Commission for variety release variety Dunav has had an average higher yield of 711 kg ha-1 than standard, and variety Vrbas higher yield of 380 kg ha-1. Both varieties are well-resistant to lodging. Variety Dunav features special quality grain with grain protein content of 16.2 %, oils 4.7 % and cellulose 9 %. Regarding growing conditions, variety Dunav is more tolerant to less favourable conditions, while variety Vrbas demands more favourable conditions to fulfill its genetic potential. .

U Institutu za ratarstvo i povrtarstvo Novi Sad nakon skoro pedeset godina inoviran je program oplemenjivanja ovsa. Iz tog programa je 2001. priznata sorta jarog golozrnog ovsa Novosadski golozrni, 2008. jara sorta plevičastog ovsa Dunav i 2009. jara sorta plevičastog ovsa Vrbas. Sorta Dunav priznata je u BiH pod nazivom Jelena. Dunav i Vrbas su heksaploidne sorte i pripadaju vrsti Avena sativa. U dvogodišnjim ogledima Komisije za priznavanje sorti koji su izvedeni na šest lokaliteta, sorta Dunav je imala u proseku veći prinos od standarda za 711 kg ha-1, a sorta Vrbas veći prinos za 380 kg ha-1. Obe sorte imaju dobru otpornost na poleganje. Sorta Dunav odlikuje se posebno kvalitetnim zrnom sa sadržajem proteina u zrnu od 16,2 %, masti 4,7 % i celuloze 9 %. U pogledu uslova gajenja sorta Dunav je tolerantnija na manje povoljne uslove, dok sorta Vrbas za realizaciju genetskog potencija zahteva povoljnije uslove. .
