Jasna: A new winter rapeseed cultivar

Abstract

The program of winter rapeseed breeding at Institute of Field and Vegetable Crops covers the development of winter and spring rapeseed cultivars and hybrids. Winter rapeseed cultivars are selected for high and stabile grain and oil yield, good oil quality, low erucic acid and glucosinolate content (type 00) and tolerance to stresses caused by abiotic and biotic factors. This paper reviews agronomic characteristics and grain and oil quality of a new cultivar of winter rapeseed Jasna. In the trials of the Serbian Commission for new cultivars registration, cultivar Jasna had higher grain yield then standard, in the three locations and two years. In average the yield was 4566 kg/ha. Oil content is at the level of the standard. The erucic acid content and glucosinolate content are lower then that in the standard and that are positive characteristics. .

Program oplemenjivanja uljane repice u Institutu za ratarstvo i povrtarstvo u Novom Sadu obuhvata stvaranje ozimih i jarih sorti, kao i hibrida. Sorte ozime uljane repice treba da imaju visok i stabilan prinos zrna i ulja, dobar kvalitet ulja, da su bez eruka kiseline, niskog sadržaja glukozinolata (tip 00) i da su tolerantne na stres izazvan abiotičkim i biotičkim faktorima. U radu su prikazane agronomske osobine i kvalitet zrna nove sorte ozime uljane repice Jasna, koja je registrovana u Srbiji 2009. godine. U ogledima Komisije za priznavanje sorti, u odnosu na standard, sorta Jasna je imala veći prinos, i u dvogodišnjem ispitivanju na 3 lokaliteta, bio je u proseku 4566 kg/ha. Sadržaj ulja je na nivou standarda. Sadržaj eruka kiseline i glukozinolata su niži od standarda, što su pozitivna svojstva. .
