Ozimi ječam - Novosadski 529 i Novosadski 535

Abstract

Novosadski 529 i Novosadski 535 po botaničkoj klasifikaciji pripadaju ozimom dvoredom ječmu Hordeum sativum ssp. distichum var. nutans. Sorta Novosadski 529 nastala je iz ukrštanja: OJK 8-82/Novo.293//Sladoran a sorta Novosadski 535 - L.107-87/Sladoran. Sorte ozimog ječma Novosadski 529 i Novosadski 535 su u trogodišnjim ogledima Savezne sortne komisije imale značajno veći prinos u odnosu na standard Novosadski 293, Novosadski 529 - 8174 kg ha-1 sorta a sorte Novosadski 535 -8947 kg ha-1 kod. Nove sorte imaju nižu stabljiku od standardne sorte, Novosadski 529 81,1 cm a sorta Novosadski 535 86,9 cm kao i bolju otpornost na poleganje. Obe sorte se odlikuju dobrom otpornošću na bolesti. Novosadski 529 je sorta krupnog zrna sa učešćem zrna I klase od 96,6% a sorta Novosadski 535 ima i udeo zrna I klase od 98,2%. Sadržaj proteina u zrnu kod obe sorte je na nivou standardne sorte Novosadski 293. Ostali ispitivani parametri koji određuju karakter zrna nisu značajno različiti od Novosadskog 293. U odnosu na postojeće sorte ozimog ječma sorte Novosadski 529 i Novosadski 535 u globalu imaju dobre agronomske i tehnološke osobine.

In botanical terms, the cultivars Novosadski 529 and Novosadski 535 are classified as two-rowed spring barley (Hordeum sativum, ssp. distichum var. nutans). Novosadski 529 was developed from the cross: OJK 8-82/Novo.293//Sladoran and Novosadski 535 from the cross: L.107-87/Sladoran. In a three-year trial carried out by the Federal Variety Commission, the two cultivars significantly outyielded the standard cultivar Novosadski 293. Compared with the standard, they have a shorter stem and better resistance to lodging. Both are also characterized by good disease resistance. Novosadski 529 is a large-grained cultivar with a 96.6% contribution of 1st class grain. In Novosadski 535, this contribution is even larger 98.2%. The grain protein content of the cultivars is similar to that of the standard, while the other parameters determining grain character did not differ significantly from Novosadski 293. On the whole, Novosadski 529 and Novosadski 535 have good agronomic and technological properties compared with the existing winter barley cultivars.
