Nove linije ozime pšenice sa poboljšanom otpornošću prema obligatnim parazitima

Abstract

Sorta Lovrin 25 i linija FR 81-19 uzete su kao izvori otpornosti prema Bumeria graminis tritici i Puccinia triticina na osnovu višegodišnjih testiranja u poljskim uslovima. Ukrštanja sa dve izuzetno osetljive sorte (Skopljanka i Barbee) prema obligatnim parazitima izvršena su 1990. godine. Kao rezultat, ovih ukrštanja, stvorene su NS RZL 225 i NS RZL 253 linije koje su posedovale odličnu otpornost ali loš tehnološki kvalitet i ostala agronomska svojstva. U 1997 godini novostvorene RZL linije ukrštene su sa, dve prinosne i raširene sorte u proizvodnji, Pesmom i Pobedom. Rezultat ovih ukrštanja su linije NS 3-4 731 i NS 3-5255 razvijene u oplemenjivačkom delu programa ozime pšenice u Naučnom institutu za ratarstvo i povrtarstvo koje se odlikuju odličnom otpornošću prema obligatnim parazitima, visokim prinosom i odličnim tehnološkim kvalitetom.

Based on the results of the trials carried out under field conditions during several years the variety Lovrin 25 and line FR 81-19 were taken as a source of resistance to Blumeria graminis tritici and Puccinia triticina. Two varieties (Skopljanka and Barbee) particularly sensitive to obligate parasites were crossed in 1990. As a result of these crossings new lines NS RZL 225 and NS RZL 253 having excellent resistance but poor technological quality and other agronomical traits were developed. Newly developed RZL lines were crossed with two high yielding varieties Pesma and Pobeda widely used in production. The results of these crossing were lines NSA 3-4731 and NS 3-5255 developed in the breeding section of the Winter Wheat Program in the Research Institute of Field and Vegetable Crops and they had excellent resistance to obligate parasites, high yielding capacity and excellent technological quality.
