Current status of broomrape (Orobanche cumana Wallr) in Serbia
(Paris : International Sunflower Association, 2008)
Broomrape is the parasitic plant that presents the major problem in sunflower production in Serbia. Since its first appearance in our country the species Orobanche cumana Wallr had been responsible for considerable yield ...
The appropriate technique for collecting and measuring the amount of floral nectar in sunflower (Helianthus annuus L.)
(Paris : International Sunflower Association, 2008)
The available techniques for collecting and measuring the amount of floral nectar are applicable but often found to be unrepresentative. Centrifugation yields larger samples but they also include nectar that is not actually ...
Uticaj globalnih klimatskih promena na pojavu i širenje volovoda u Srbiji
(Beograd : Društvo za zaštitu bilja Srbije, 2009)
Promena klime ne utice samo na gajenje biljke vec dovodi do promene u razvoju stetnih organizama. Klimatske promene uticu na rezistentnost biljaka domacina i dovode do promena u interakciji domacin patogen. Najcesce promene ...
Achievements of sunflower breeding / Dostignuća u oplemenjivanju suncokreta
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)
Over the four decades of sunflower breeding at the Institute of Field and Vegetable Crops in Novi Sad (IFVCNS), significant results have been achieved. In the area of genetic resources, over 7,000 inbred lines originating ...
Results of a two-year study of Novi Sad sunflower hybrids in small: Plot trials / Rezultati dvogodišnjih ispitivanja novosadskih hibrida suncokreta u mikroogledima
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)
In 2004, conditions for sunflower production were highly favorable and high yields were obtained both in trials and large-scale production (2.34 t/ha). In 2005, however, abundant precipitation throughout the growing season ...
Gene effect and combining abilities for plant height and head diameter in sunflower / Efekat gena i kombinacione sposobnosti za visinu biljke i prečnik glave kod suncokreta
(Društvo genetičara Srbije, Beograd, 2005)
Plant height and head diameter are important parameters which effect on a yield in sunflower. Six restorer Rf lines, three tester A lines and their 18 Fl hybrids were studied, using line x tester method. Significant ...
Evaluation of production characteristics of NS sunflower hybrids / Ocena vrednosti produktivnih svojstava NS-hibrida suncokreta
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2005)
Used to evaluate the production characteristics of NS sunflower hybrids were the results from large-scale commercial production and the mean, minimum and maximum values of seed yield, oil yield and seed oil content from ...
The use of new Rf inbred lines originating from interspecific population with H. deserticola for the production of sunflower hybrids resistant to broomrape
(Paris : International Sunflower Association, 2008)
One of the directions in sunflower breeding is selection for the resistance to broomrape. The population of broomrape has been stable in Serbia for a longer period of time, but the racial composition has changed in recent ...
Intervarietal Differences in Response of Sunflower (Helianthus annuus L.) to Different Mutagenic Treatments
(Rome : FAO, 2009)
For much of the past century, mutagenesis has gained popularity in plant genetics research as a means of inducing novel genetic variation. Induced mutations have been applied for the past 40 years to produce mutant cultivars ...
