Pregled proučavanja populacije Puccinia graminis Pers. f. sp. Tritici Erikss. et Henn. u Srbiji / Investigations of the Puccinia graminis f. sp. tritici Erikss. et Henn. population in Serbia - an overview
(Beograd : Društvo za zaštitu bilja Srbije, 2004)
Prva proučavanja populacije P. graminis tritici u Srbiji započeta su krajem 50-tih godina XX veka. U dosadašnjim proučavanjima razlikuju se dva perioda: prvi obuhvata identifikaciju fizioloških rasa pomoću standardnih ...
Control of Orobanche cernua in imidazolinone-tolerant sunflower hybrids
(Amsterdam : International Parasitic Plant Society, 2004)
Sunflower breeding for tolerance to imidazolinone-based herbicides began in 1997, and many sunflower seed companies and institutes are actively developing so-called Clearfield* sunflower hybrids tolerant to imidazolinone-based ...
Inheritance of some yield components in sunflower
(Paris : International Sunflower Association, 2004)
In order to study the mode of inheritance and gene effects for seed set, autofertility and self-fertility, half diallel crosses with five divergent sunflower inbred lines were made. The effects of additive, dominant and ...
Genetic divergence in sunflower (Helianthus annuus) inbreds
(Paris : International Sunflower Association, 2004)
Increase in seed yield is the main objective of sunflower breeding programs. Genetic variability is the basic prerequisite for each breeding program. Determination and knowledge of genetic variability facilitate the selection ...
Screening for virulence of Blumeria graminis tritici using mobile nurseries
(Novi Sad : University of Novi Sad, Faculty of Agriculture, 2004)
Blumeria graminis tritici, the causal agent of Powdery mildew, is a regular and economically important disease of wheat in Serbia and a major disease problem in wheat crops in Europe, particularly in northern and western ...
Nove linije ozime pšenice sa poboljšanom otpornošću prema obligatnim parazitima / New winter wheat lines with improved resistance to obligate parasites
(Beograd : Društvo za zaštitu bilja Srbije, 2004)
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 ...

Correlation of yield components and seed yield per plant in sunflower (Helianthus annuus)
(Paris : International Sunflower Association, 2004)
Studied in this paper was the interdependence of six morphophysiological sunflower traits (petiole angle, petiole length, total leaf number per plant, total leaf area per plant, plant height and head diameter) and their ...
The new method of relating wheat genotypes seedlings to Puccinia tritici resistance characters in greenhouse with maximal infection intensity in field
(Novi Sad : Univerzitet u Novom Sadu, Poljoprivredni fakultet, 2004)
The method for differing the wheat genotypes according to reaction type at seedling stage was not efficient in separating the pseudo resistant ones. The characters like low infection efficiency and prolonged latency period ...
Influence of several wheat pathogens on the leaf rust development
(Novi Sad : University of Novi Sad, Faculty of Agriculture, 2004)
The investigations of the interactions between pathogens could be interrupted by single strong development of each on the same plant. The adequate methods were not developed until nowadays. The protection by fungicides ...
