Stamena winter wheat variety

Abstract

Stamena is a winter wheat variety developed at the Institute of Field and Vegetable Crops in Novi Sad, Yugoslavia. It was released by the Federal Commission for varietals Approval in 1999. Stamena was developed by crossing genetically divergent and highly productive parents Lasta and Rodna (Breeders: T. Mišić. N. Mladenov, Z. Jerković and R. Jevtić). Spike is white, smooth, awn less, medium compact with 18-21 spike lets. The grain is vitreous and dark red (Triticum aestivum L. ssp. vulgar e var. lutescens). Stamena is a medium early variety, 1 day earlier than Partizanka and 3 days earlier than Jugoslavija (Table 4). It has excellent resistance to winterkilling, as in very winter hardy Partizanka. The average stem height is 78 cm, with a good resistance to lodging. Stamena has field resistance to leaf rust (Pucce, recondita tritict), horizontal resistance, which is the type of resistance that modern wheat breeding is interested in. The resistance to stem rust (Pucce, graminis tritict) is good and to powdery mildew (Erysiphegraminis tritici) very good. The 1000 grain mass is about 32 g and volume grain mass 81.3 kg/hi. (Table 2). Stamena is classified in the subgroup A-l. It has excellent milling and baking quality and it belong to the 1st technological group (quality enhancer). The quantity of dry gluten is about 9%. The variety Stamena is a very productive, with the genetic potential for grain above 11 t/ha suitable for growing on fertile and less fertile soils. It has started to be grown commercially in 2000.

Ozima, srednje rana sorta pšenice Stamena, oplemenjena je metodom proste hibridizacije genetički divergentnih roditelja, sorti Lasta i Rodna. U njoj su vrlo uspešno kombinovani geni koji kontrolišu glavne agronomske osobine: potencijal prinosa zrna iznad 11 t/ha, odličan tehnološki kvalitet na nivou poboljšivača, visoka otpornost prema niskim temperaturama i mrazu kao i pojavama koje prate mraz (golomrazici i suvomrazici), poljska otpornost prema prouzrokovaču lisne rđe (Pucce. recondita tritict) i dobra otpornost prema stabljičnoj rđi i vrlo dobra prema pepelnici (Pucce. graminis tritici, Erysiphe graminis tritici), srednje niska stabljika, oko 78 cm visine i dobra otpornost prema poleganju. Ističe se velikom biološkom plastičnošću i sposobnošću adaptacije različitim klimatsko-zemljišnim uslovima. Vrlo je perspektivna sorta. Registrovanje od strane Savezne komisije za priznavanje sorti 1999 godine (selekcioneri T. Mišić, N. Mladenov. Z. Jerković i R.Jevtić).
