NS Lenija - nova sorta ozime pšenice

Abstract

Prilikom stvaranja novih sorti pšenice (Triticum aestivum L.), pored visokog potencijala za prinos i dobrog tehnološkog kvaliteta neophodno je i inkorporirati gene odgovorne za otpornost prema poleganju, niskim temperaturama i adaptabilnost na različite uslove proizvodnje. NS Lenija, nova sorta ozime pšenice stvorena u Institutu za ratarstvo i povrtarstvo (Institut od nacionalnog značaja za Republiku Srbiju) nastala je veštačkim ukrštanjem tri divergentna roditelja: sorte Kupava (Rusija) i sorti Donna (Srbija) i Arija (Srbija). Ukrštanjem ovih roditelja uspešno su iskombinovani geni odgovorni za visok potencijal za prinos, dobar tehnološki kvalitet, adaptabilnost i stabilnost, koji omogućavaju da se ova sorta može uspešno gajiti u agroekološkim uslovima Jugoistočne Evrope. Tokom trajanja dvogodišnjih ogleda Komisije za priznavanje sorti, NS Lenija je uspešno prošla DUS test (različitost, uniformnost i stabilnost), i na 7 ispitivanih lokaliteta ostvarila je u proseku značajno veći prinos zrna u odnosu na prosek prinosa zrna sorti standarda. Prilikom ocena hemijsko-tehnoloških osobina, svrstana je u kvalitetnu klasu II, u farinogramsku kvalitetnu grupu A-2, i u tehnološku grupu poboljšivača.

During the creation of new wheat cultivars (Triticum aestivum L.), in addition to high yield po tential and good technological quality, it is necessary to incorporate genes responsible for resistance to lodging, low temperatures and adaptability to different production conditions. NS Lenija, a new winter wheat cultivar developed at the Institute of Field and Vegetable Crops (National Institute of the Republic of Serbia) was created by crossing the three divergent parents: cultivar Kupava (Russia) and the cultivars Donna (Serbia) and Aria (Serbia). By crossing these parents, genes responsible for high yield potential, good technological quality, adaptability and stability were successfully combined, enabling this cultivar to be successfully cultivated in the agroecological conditions of Southeast Europe. During the two-year trials of the Commission for the registration of varieties, NS Lenija successfully passed the DUS test (distinctness, uniformity and stability), and on the 7 tested locations achieved a significantly higher average grain yield compared to the grain yield of the check cultivars. When evaluating its chemical and technological properties, it was classified in quality class II, farinograph quality group A-2, and in the technological group of improvers.
