Combining ability's for yield components in sunflower / Kombinirajuće sposobnosti za komponente prinosa suncokreta
(Društvo selekcionara i semenara Republike Srbije, Beograd, 2000)
In order to develop new single-cross sunflower hybrids with an altered plant model and a high genetic potential for seed yield and oil content, it is essential to study the combining ability's of the inbred lines. Full ...
Heterosis for hull number and seed yield per plant in oil rape (Brassica napus L.) / Efekat heterozisa za broj ljuski i prinos semena po biljci kod uljane repice (Brassica napus L.)
(Društvo selekcionara i semenara Republike Srbije, Beograd, 2000)
Heterosis for hull number and seed yield per plant was studied in the hybrid combinations of the F, generation obtained by diallel-crossing five cultivars of winter oil rape. A trial with the parental lines and F, hybrids ...
Tolerance of wheat genotypes to lead in in vitro culture / Tolerantnost genotipova pšenice prema olovu u kulturi in vitro
(Društvo selekcionara i semenara Republike Srbije, Beograd, 2000)
We studied the effects of five lead concentrations (10-7, 10-6, 10-5, 10-4 and 10-3 M) on callus growth and dry matter content in the callus tissue. Two winter wheat (Triticum aestivum L.) cultivars, Balkan and Proteinka, ...
Seed production in cabbage / Semenska proizvodnja kupusa
(Društvo selekcionara i semenara Republike Srbije, Beograd, 2000)
In this region, cabbage has a long tradition of growing and a variety of possible uses. Because of this, high-quality seed production is required. Cabbage is a biennial, open-pollinated crop whose seed production requires ...
Sugarbeet breeding: Situation, prospectives and limitations / Oplemenjivanje šećerne repe - stanje, mogućnosti i ograničenja
(Društvo selekcionara i semenara Republike Srbije, Beograd, 2000)
Breeders of sugar beet (Beta vulgaris L.) use a variety of conventional breeding methods and novel techniques striving to protect, maintain and expand the genetic variability of the crop, develop superior hybrids, and ...
Testing of regeneration ability of protoplasts isolated from different genotypes of cultivated sunflower / Testiranje regeneracione sposobnosti protoplasta izolovanih iz različitih genotipova gajenog suncokreta
(Društvo selekcionara i semenara Republike Srbije, Beograd, 2000)
Protoplasts isolated from different genotypes of cultivated sunflower differ in their ability to divide and regenerate in culture. Since plant regeneration is ultimate goal of protoplast culture and since regeneration ...
Improvement of combining abilities of sugar beet population C-8173 using in vitro methods / Mogućnost poboljšanja populacije oprašivača korišćenjem in vitro metoda
(Društvo selekcionara i semenara Republike Srbije, Beograd, 2000)
The ultra sugary cultivar Crvenka mz, released in 1997, is a triploid whose parental components are the monogerm cms line A-0401 and the multigerm tetraploid population C-8173. The objective of our study was to select from ...
Maturing of different types ok sugar beet / Proces sazrevanja različitih tipova sorti šećerne repe
(Društvo selekcionara i semenara Republike Srbije, Beograd, 2000)
Levels of sugar and non-sugar (K, Na and amino N) depend on environmental conditions and cultural practices applied. At the same time, these traits are an important characteristic of every cultivar. A number of parameters ...
Using callus culture to study the drought tolerance of wheat genotypes / Korišćenje kalusne kulture za ispitivanje tolerantnosti genotipova pšenice prema suši
(Društvo selekcionara i semenara Republike Srbije, Beograd, 2000)
In this paper, we studied the drought tolerance under in vitro conditions of two winter wheat (T. aestivum L.) cultivars, Košuta and Renesansa. The tolerance was tested on a modified MS (Murashige and Skoog, 1962) nutrient ...
Correlations between photosynthetic indicators and vegetative mass yield in red clover (Trifoliumpratense L.) / Korelacije fotosintetičkih pokazatelja i prinosa vegetativne mase kod crvene deteline (Trifolium pratense L.)
(Društvo selekcionara i semenara Republike Srbije, Beograd, 2000)
Experiments were conducted at the Rimski Šančevi Experiment Field in the period 1998-1999 The experiment object were six varieties and two populations of red clover. In both years, we determined photosynthetic indicators ...
