    Following long pepper, tomato is most widely cultivated vegetable in the Republic of Macedonia. It is mainly grown under tunnels and in glasshouses. Considerable portion of the production is intended for export during April, May and June, whereas the local markets are supplied with imports for the rest of the year. A survey has been carried out at the beginning of 2016 aiming to determine consumer preferences for fresh tomato among 50 fresh markets and distributors. It was concluded that consumers prefer to buy local landraces over hybrids. Landrace with apple shaped tomato fruit (Yabuchar) is favorite one for the buyers. In order to enrich the offer of the local tomato producers, 10 Yabuchar-type tomato landraces, collected from different villages and producers during 2016 have been tested for their productive and qualitative traits. Field trials were carried out in the villages of Drachevo and Lisiche, both in vicinity of the capital, Skopje. The landraces were grown in open field conditions following standard agricultural practices for this type of tomato. The characterization of the examined landraces was made by IPGR descriptor for tomato (Lycopersiocon esculentum Mill.). Although all these landraces appear under the same name, significant distinctiveness has been recorded regarding morphological traits such as flower morphology, shape and size of the fruits, pericarp thickness, cracking and green zone of the fruits and mass of the fruits, as well as in the content of sugars. Main drawback for wider production of these landraces is generally short shelf live that might be improved in further breeding programs.

    The aim of this study was to examine germination rate and morphological characteristics of English marigold seedlings under influence of different light conditions. Seeds of Calendula officinalis L. were collected from the natural population of the Botanical garden of the University of Banja Luka. Experiment was set up in four replicates for each light treatment. Petri dishes with seeds were placed in growth chamber under artificial white (FLUO) and blue, red, and combination of blue/red (LED) light with 16h/8h photoperiod. Germination energy was tested after 7 days and germination of the seeds was tested after 14 days. Results showed significant difference in germination energy, germination rate, hypocotyl height, root length, and fresh weight. The highest average values of the germination energy and germination rate of the Calendula officinalis L. were recorded under red LED light (32%; 47%) while the lowest values were recorded under blue LED light (1%; 23%). The highest average values of hypocotyl height, root length and fresh weight were recorded also under red LED light (3,70 cm; 6,33 cm; 0,97 g) while the lowest values were recorded under combination of blue/red LED light (1,95 cm; 2,52 cm; 0,28 g). It can be concluded that the use of red LED light is recommended in the seed germination phase, not only for better germination but also for better morphological development.
