Prima, vrlo rana patuljasta sorta ozime pšenice

Abstract

Ozima, vrlo rana i patuljasta sorta pšenice Prima stvorena je ukrštanjem genetički divergentnih i intenzivnih sorti i linija Tobary 66, Kavkaz, Nova Banatka, NS 3143, Rana niska i NS 3985/1 metodom sukcesivne hibridizacije. U sorti Prima uspešno su kombinovani geni odgovorni za visok genetički potencijal za prinos zrna, vrlo dobar tehnološki kvalitet, ranozrelost i otpornost prema poleganju, bolestima i niskim temperaturama. Za redukciju visine stabljike i ranozrelost korišćeni su geni Rht 2 i Ppd 1 iz Norin 10 (Tobary 66 i Rana niska) i Rht 1S iz Saitama 27 (NS 3985/1). Savezna komisija za priznavanje sorti registrovala je Primu 1995. godine.

Very early winter wheat variety Prima was released by the Federal Comission for Varietal Approval in 1995. It was developed by crossing genetically divergent and highly productive varieties Tobary 66, Kavkaz, Nova Banatka, NS.3143, Rana niska and NS.3985/1. The spike in white and smooth, compact and awnless, with 18-22 spikelets; the grain is witreous and red (Triticum aestivum L ssp. vulgare var. lutescens). Prima is a dwarf variety with the average strow height of about 73 cm, with very good resistance to lodging. It is very early variety with good resistance to winterkilling. Its resistance to leaf rust (Pucc. recondita tritici) is excellent, the resistance to stem rust (Pucc. graminis tritici) and powdery mildew (Erysiphe graminis tritici) is good. Apsolute mass of 1000 grains is about 33 g, volumic mass of about 85 kg/hi. The variety is classified in the quality subgroup A2. The milling quality is excellent, the baking quality is very good to excellent. According to the indicators of technological quality Prima is classified in the II technologic group as an very good bread variety. The variety is very productive, with the genetic potential for grain yield above 11 t/ha and suitable for growing on fertile soils and intensive production conditions. Prima is a important genotype for profitable production at a high level of intensity. .
