“…Tomato genotypes that are the carriers of Ph-2 gene of resistance to this parasite were crossed with tomato genotypes with good production characteristics (yield and fruit quality) but more susceptible to this parasite. Successfully were selected tomato lines and hybrids that expressed a higher level of resistance than their parents (MIJATOVIC et al, 2007;.…”

The remarkable development and application of new genetic The Institute for Vegetable Crops possesses a rich germplasm collection of vegetables, utilized as gene resource for breeding specific traits. Onion and garlic breeding programs are based on chemical composition improvement. There are programs for identification and use of genotypes characterized by high tolerance to economically important diseases. Special attention is paid to breeding cucumber and tomato lines tolerant to late blight. As a result,

“…Resistant hybrids have been obtained by crossing varieties and lines (originating from Wva'63, Wva'700, Pieraline) with the gene Ph-2, on one hand and lines and varieties with good combining ability for yield and quality characteristics of fruit but not resistant to the parasites, on the other. The achieved resistance in this line has been incorporated in the hybrid combinations (Zdravkovic et al, 2001(Zdravkovic et al, , 2004 and the nature of late blight isolates in Serbia (Mijatovic et al, 2004) has been examined. The gene (Ph-2) has been incorporated by many researchers (Gajc-Wolska and Michalska, 2002).…”

Late blight (Phytophthora infestans (Mont.) de Bary) was identified as one of the major diseases causing significant economic losses in tomato production. Thus, the development of resistant cultivars and hybrids was included in tomato breeding programs at the Institute for Vegetable Crops, Smederevska Palanka. A line (S-31), Tomato late blight resistance gene Ph-2 carrier, was diallely crossed with four susceptible lines possessing good production characteristics (S-49, S-31, hom-3 and hom-4) in order to obtain resistant high-yield and quality hybrids. Parental lines and five F1 hybrids, as well as three commercially grown susceptible cultivars (Narvik SPF, Adonis, SP-109, negative control) were tested for resistance toward this pathogen. Sensitivity was evaluated ten days after inoculation on the basis of leaf area necrotic spot, using I to VI level scale. The results imply dominant or partially dominant inheritance pattern. Three commercially grown cultivars were susceptible, as expected. Five of F1 hybrids including S-31 and hom-3 parents were resistant to late blight. The best hybrids were S-31 x hom-3 and S-31 x hom-4 when the morphological traits, yield and resistance were taken into account. Obviously, lines from group hom contributed to increased resistance to tomato late blight with respect to resistant parent.
