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 ...
Correlation between macronutrient content and sunflower resistance to Sclerotinia sclerotiorum measured by sclerotia infection of stem
(Paris : International Sunflower Association, 2008)
Nutrition of plants has a substantial impact on the predisposition of plants to be attacked or affected by pests and diseases. Since availability and nutrient quantity in the host plants is a limiting factor for Sclerotinia ...
Use of additive-dominant model in genetic analysis of some quantitative caracteristics in sunflower
(European Association for Research on Plant Breeding, 2006)
A simple link between the expected means of quantitative traits of different generations (progenies) can be established if the mean values are dependant exclusively on additive and dominant gene effects. Th is study aims ...

Uslovi proizvodnje strnih žita u 2001/02. godini
(Novi Sad : Institut za ratarstvo i povrtarstvoNovi Sad : Semenarstvo, 2002)
Završni period vegetacije strnih žita 2001/02. ne obećava visoku proizvodnju. Naprotiv, kao i tokom većeg dela dosadašnjeg toka, i u završnom periodu vladaju veoma nepovoljni vremenski uslovi. Suša i nešto više temperature ...
Gene actions for seed yield in sunflower (Helianthus annuus)
(Paris : International Sunflower Association, 2004)
Effects of additive and dominant genes and their interactions on the inheritance of seed yield in 10 sunflower hybrids developed by crossing five inbred lines derived from the synthetic NS-S-1 were analyzed in 2001 and ...
Osetljivost sorti pšenice prema Pyrenophora tritici-repentis, prouzrokovaču žutomrke pegavosti
(Beograd : Društvo za zaštitu bilja Srbije, 2006)
Simptomi žutomrke pegavosti lista pšenice prvi put su zapaženi 1993. u lokalitetu Nikinci, a prvo saopštenje o pojavi i rasprostranjenosti Pyrenophora tritici-repentis u Srbiji, dato je 1997. godine od strane Jevtića. Na ...
Uticaj načina prenošenja Tilletia tritici i rokova setve na visinu biljaka i zaraženost klasova
(Beograd : Društvo za zaštitu bilja Srbije, 2001)
Glavnica pšenice se ponovo masovno javila na žitnim poljima početkom 90-tih godina, kada je uvođenjem sankcija našoj zemlji izostala primena fungicida za tretiranje semena, a na 50-60% površina obavljana je setva nedeklarisanim ...
