“…Kasnije su se oplemenjivanjem dobili kultivari koje danas nazivamo "modernim kultivarima". Broj vrsta koje su sudjelovale u stvaranju tih kultivara nije velik (između 8 i 20) pogotovo kada se usporedi s ukupnim brojem vrsta unutar roda Rosa (De Vries and Dubois, 1996). Međutim, to ne mora značiti da je varijabilnost genetske osnove tih kultivara također razmjerno mala.…”

SažetakPasja ruža (Rosa canina L) jedna je od najraširenijih samoniklih pripadnika roda Rosa u našoj zemlji, te prilično zastupljena u prirodnim, ruralnim pa i urbanim područjima. Iako se u svijetu pasja ruža proučava, uzgaja i oplemenjuje, u Hrvatskoj njezin uzgoj gotovo i ne postoji. U prirodi se mogu uočiti velike razlike među biljkama, posebno s obzirom na veličinu plodova, često i na vrlo malim staništima. Istraživanje je provedeno na 8 grmova pasjih ruža na oko 1 ha zapuštene poljoprivredne površine pokušališta 'Jazbina' u Zagrebu. Po 120 plodova u tehnološkoj zriobi nasumično je ubrano sa svakog grma. Prosječna masa ploda kretala se od 1,88 do 2,96 g, a prosječni udio svježeg mesa u plodovima od 65,4 do 74,7 %. Prosječni udio suhe tvari mesa (nakon sušenja na 105°C) u odnosu na težinu svježeg ploda varirao je od 22,9 do 28,6 %. Plodovi istraživanih biljaka statistički su se razlikovali (P≤0,05) po dimenzijama (duljina, širina, debljina), i obliku, a kako su biljke rasle u ujednačenim klimatskim i edafskim uvjetima može se zaključiti da na ovom malom lokalitetu postoji razmjerno velika fenotipska, a time vjerojatno i genotipska varijabilnost biljaka pasje ruže. Uz opravdanu pretpostavku da na području Republike Hrvatske ima mnogo sličnih staništa pasje ruže, rezultati ovog istraživanja ukazuju na bogati genetski potencijal pasje ruže koji bi se mogao iskoristiti za početnu selekciju biljaka superiornih svojstava namijenjenih uvođenju u kulturu. Ključne riječi: Rosa canina L., pasja ruža, stanište, varijabilnost biljaka, selekcija Abstract A dog rose (Rosa canina L) is one of the most widespread wild species of the genus Rosa in our country, and fairly represented in the natural, rural and even urban areas. Although in the world a dog roses are studied, cultivated and refined, in Croatia its cultivation almost does not exists. In nature you can see major differences between plants, especially considering the size of the fruit, often in very small habitats. The study was conducted at 8 rose dog bushes at about 1 ha of abandoned experimental field 'Jazbina' in Zagreb. From each plant, 120 fruits were randomly collected at a technological maturity. The average fresh fruit weight ranged from 1.88 to 2.96 g, the average fresh flesh portion from 65.4 to 74.7 % and the average dry flesh matter content (after drying at 105 °C), in relation to the fresh fruit weight, from 22.9 to 28.6 %.

“…Introduction of new genotypes and replacement of species and cultivars by travelers significantly increases the genetic changes to the horticulturists and the propagation of the species: this importantly involved a decreasing of genetic changes available [1]. The establishment of cultivar of roses is mainly has three equal phases: the past (1876-1968) and the future (1966) moreover significant achievements are underlined [1] Considered that of the 250-350 identified species of rose, only [15][16][17][18][19][20][21][22][23][24][25] have added to the growth of some new cultivars of rose. Rose breeding majorly attempted by developed companies and their checked inherited awareness [1].…”

Among the highly fragrant rose species, R. centifolia and R. gruss an teplitz have high commercial importance and value added potential. Most of the modern roses are the result of hybridization, selection and spontaneous mutation. For floriculture trade, there is always demand and necessity for new varieties due to change in taste and fashion. Mutation breeding is an established method for crop improvement. Mutant lines were taken from the Plant Tissue Culture Laboratory of Department of Horticulture, PMAS-Arid Agriculture University, Rawalpindi. Rose genotypes mutants were sown in the field at similar conditions of irrigation, fertilizers and pest/disease management. Plants were treated with different levels of gamma rays and colchicine through solution. Data of various parameters like plant height shoot length, fresh leaf weight, dry leaf weight, flower diameter, rose water, number of shoots, number of flowers/plant/week, weight/10 flowers and number of petals were collected for different treatments. Gamma radiations show greater improvement in R. centifolia but colchicine impact was more on R. gruss an teplitz.

“…There are about 240-300 recognized rose species, of which only 10-20 have contributed to the development of modern rose cultivars. Rose breeding is mainly carried out by highly competitive private companies and their applied genetic knowledge is proprietary and unpublished (de Varies and Dubois, 1996). Documentation in many rosaries and rose collections indicates numerous problems of misidentification, mislabeling and incomplete denomination of taxa.…”
