To be successful in establishing in crop fields, weeds must tolerate soil disturbance, synchronise their germination time and emergence with the crop and with management interventions as well as with the growth of neighbouring plants to reduce competition (Tominaga and Yamasue, 2004). In addition, fields are fertilised and irrigated; therefore to become established, a successful weed species should be able to monopolise resources in favour of its own growth and to increase its suppressive effect (Kaur et al., 2018). Another important characteristic of weeds is their ability to grow at high density and still maintain high reproductive output (Yannelli et al., 2017). Ambrosia artemisiifolia L. (common ragweed), hereafter referred to as AA, is both a highly noxious plant due to its negative impacts on human health caused by its allergenic pollen and an important weed of spring sown crops (Kazinczi et al., 2008). A recent study reported that around 13.5 million people suffer from common ragweed-induced allergies in Europe, causing economic costs of

Summary:In different regions of Serbia people consume pepper fruits with various shapes, sizes and colors. In southern Serbia consumers prefer longer fruits, while in the northern part shorter fruits are more preferred. The aim of this paper was to evaluate four pepper genotypes (355, 356, 357, and 358) with shorter fruits originating from open pollination. These genotypes were compared with the parental line 354 with longer fruits. The fruits were harvested in technological maturity. Fruit (length, width, weight, and index), locule number, pericarp thickness, total soluble solids and fruit yield per plant were evaluated. The line 354 had the longest fruits (14.46 cm). Genotype 358 had the highest pericarp thickness (5.8 mm), while the genotype 357 had the highest fruit weight (105 g). Based on the evaluated traits, genotype 357 will be used for further selection because of higher fruit weight, and genotype 358 because of a thicker pericarp.
