Genetske analize roditelja u selekciji pšenice prema obligatnim parazitima / Genetic analysis of parents in wheat breeding to obligate parasites resistance
(Beograd : Društvo genetičara Srbije, 1999)
Osnovni preduslov za uspešnu selekciju na otpornost prema obligatnim parazitima je različitost roditelja po genima koji tu osobinu kontrolišu. Broj gena i njihove interakcije, bez obzira na vrstu otpomosti, od presudnog ...
Tilletia vrste na pšenici: rasprostranjenost, suzbijanje i uticaj na prinos i kvalitet proizvoda
(Beograd : Društvo za zaštitu bilja Srbije, 1997)
Prema Neergaardu (1983) postoji 5 značajnih rodova fitopatogenih gljiva koje se prenose semenom pšenice. To su Tilletia, Ustilago, Fusarium, Drechslera i Septoria od kojih su prouzrokovači glavnice (Tilletia) i gari ...
Broj teleutospora Tilletia tritici kao pokazatelj kontaminiranosti zrna pšenice
(Novi Sad : Univerzitet u Novom Sadu, Tehnološki fakultet, 1997)
Biljke pšenice zaražene glavnicom ne mogu se prepoznati sve do pojave klasa iz rukavca. Zaraženi klasovi imaju nijansu plavičaste boje. Bolesna zrna su nesto šira, buretasta i imaju tamnoplavu boju. Promena boje zrna nastaje ...
Virulentnost Erysiphe graminis· f. sp. tritici / Virulence of Erysiphe graminis· f. sp. Tritici
(Novi Sad : NIŠP Dnevnik, 1990)
Prouzrokovač pepelnice (Erysiphe graminis tritici) može u znatnoj meri da utiče na prinos pšenice. Najpouzdaniji i najekonomičniji način zaštite je selekcija i gajenje otpornih sorti. Uspeh u selekciji, pored ostalog zavisi ...
