The basic parameter of re-introduction of this crop into the crop rotation in Slovenia is testing and trials of sunflower cultivars (Helianthus annuus L.), that could be suitable for the growing ...conditions in Slovenia, for the purpose of organic production and for the production of healthy food for consumers. On the experimental field at Biotechnical Faculty, in the period from 2002 to 2006, we were testing certain economically significant properties of five sunflower cultivars: Kernal, Kongo, Delija, Goleador and Iregi szürke csíkos. Seeds were sown by hand to the parcel in the size of 3 m x 11.8 m. Under the growing conditions in central Slovenia the genetic potential of hybrids for the production above 4 t of seed/ha was almost reached and closely approached by the hybrids Kongo and Kernal with average yields 3.5 t/ha and 3.3 t/ha. Yields of Delija and Goleador hybrids were about 1 to 1.2 tons lower, but mutually comparable. The lowest yield (1.6 t/ha) was given by Iregi szurke csikos variety, which is mostly grown by the producers in Slovenia, mainly because it is used and sold as a bird feed. In the year 2003, the fat content in the seed obtained from the hybrids, reached from 38 to 42 %, for Iregi szurke csikos variety it was only 33 %, on the other side - in the year 2005 - the fat content in the seed obtained from the hybrids was higher, that is 39 to 45 %, and for the Iregi szurke csikos variety the average was the same as in the year 2003. The highest fat content in the seed was reached by highly oleic hybrid Goleador, that is 42 % in the year 2003 and 45 % in 2005; for this hybrid, during this two years of the trials the 78- to 79-percent content of oleic acid in the oil was a little lower than its genetic potential, which is above 80 %. Regarding the use of the crop - for the cold pressed oil - the most important cultivars are the highly oleic hybrid Goleador and semioleic Delija, and for the bird feed instead of the Iregi szurke csikos variety we could sow Kongo and Kernal hybrids, not only due to their higher yields, but also due to higher fat content. Experts can advise producers how they can increase their production of seeds and oil only on the basis of tested, high quality and accessible sunflower assortment.
Preizkušanje kultivarjev sončnice (Helianthus annuus L.), ki bodo ustrezali rastnim razmeram v Sloveniji, potrebam sonaravne pridelave in potrošnikom zdrave hrane, je temelj ponovnega uvajanja te poljščine v kolobar. Na poskusnem polju Biotehniške fakultete smo v obdobju 2002 do 2006 preučevali nekatere gospodarsko pomembne lastnosti petih kultivarjev sončnice: Kernal, Kongo, Delija, Goleador in Iregi szürke csíkos. Seme smo posejali ročno na parcelo velikosti 3 m x 11,8 m. Genskemu potencialu hibridov za pridelek nad 4 t semena/ha sta se v rastnih razmerah osrednje Slovenije najbolj približala hibrida Kongo in Kernal s povprečnima pridelkoma 3,5 t/ha in 3,3 t/ha. Pridelek hibridov Delija in Goleador je bil za 1 do 1,2 toni manjši, vendar med seboj primerljiv. Najmanjši pridelek je dala sorta Iregi szurke csikos (1,6 t/ha), ki jo pridelovalci sončnice v Sloveniji sejejo največ, ker je v prodaji za krmo ptic. Vsebnost olja v semenu v letu 2003 je bila pri hibridih od 38 do 42 %, pri sorti Iregi szurke csikos pa le 33 %, nasprotno pa je bila oljnatost semena v letu 2005 pri hibridih večja, to je 39 do 45 %, pri sorti Iregi szurke csikos pa približno enaka kot v letu 2003. Največjo vsebnost olja v semenu je imel visoko oleinski hibrid Goleador, in sicer 42 % v letu 2003 in 45 % v letu 2005; 78- do 79- odstotna vsebnost oleinske kisline v olju pa je bila v obeh letih nekoliko manjša od njegovega genskega potenciala za to lastnost, ki je nad 80 %. Glede na namen uporabe pridelka sta za hladno stisnjeno olje najprimernejša visoko oleinski hibrid Goleador in pol oleinski Delija, za krmo ptic pa bi lahko namesto sorte Iregi szurke csikos sejali hibrida Kongo in Kernal, ne le zaradi večje rodnosti, ampak tudi zaradi večje vsebnosti maščob. Le na podlagi preizkušenega, kakovostnega in dostopnega sortimenta sončnice bodo lahko strokovnjaki svetovali pridelovalcem, tako, da bodo ti pridelali več semena in maščob.

Več kot 65 % beljakovin in več kot 80 % energije zaužijemo z rastlinsko hrano. Metuljnice zato zavzemajo posebno mesto pri prehrani, ker vsebujejo skoraj dva do trikrat več beljakovin kot žita. So ...tudi pomemben vir energije, več vitaminov skupine B-kompleks, esencialnih elementov in vlaknine. Beljakovine so nekoliko slabše kakovosti zaradi pomanjkanja žveplo vsebujočih aminokislin, vendar če jih uživamo v kombinaciji z žiti, dosežemo zgleden dopolnjujoč učinek. Navajamo nekaj najpogostejših antihranilnih spojin, ki so v zrnju metuljnic, njihov vpliv na hranilno vrednost in uporabo metuljnic v prehrani.

Irradiation of F 1 and F 2 seeds from the interspecific cross Gossypium hirsutum L x G. barbadense L revealed greater possibilities for its efficient use in genetic and breeding investigations. ...Combined experimental mutagenesis with distant hybridization of G. hirsutum x G. sturtii F. Mill proved exceptionally efficient also for accelerating the breeding process and for development of valuable forms for breeding. Irradiation of F 1 G. hirsutum x G. sturtii seeds followed by colchicine treatment of F 1 plants (2n=39) in the phase of cotyledons resulted in the development of mutant-hybrid forms, which resemble the cultivated species G. hirsutum and possess a number of valuable characters from the wild growing species. This method may prove very important for use in distant hybridization aiming to use the genetic potential of wild growing species.

The possibilities of introducing biochemical methods (electrophoresis of enzymes, zeins, RFLPs, RAPDs, microsatellites) for the identification of genotypes in maize breeding and seed production are ...discussed in the present article. The conclusion is reached that in conditions of market economics in seed production it is absolutely necessary to introduce electrophoretic control in evaluating the quality of hybrid seeds in respect to their hybridity and authenticity. The first steps for introducing these methods are: 1. Obligatory registration of the component lines of regionally distributed hybrids in the State Cultivar Commission (SCC) by electrophoretic formulae; 2. Standartization of the zein and isoenzyme methods of electrophoresis. 3. Accreditation of independent laboratories for electrophoretic control according to the acting BSS, among which is the Reserch Laboratory for Electrophoresis of the Maize Institute, Khezha.
A laboratory installation for radiation treatment of seeds through the use of high energy rays was set up. Mercury-vapour lamps were used as ultraviolet rays source. Experiments were carried out by ...radiation treatment of tomato, melon and pepper seeds. It was found that after radiation treatment of tomato seeds their laboratoy germination rate rose by 8.5 to 10.0, while those of the pepper and of the melon rose 5.0 and 4.5 respectively.
