Thirty accessions of tomato including twenty eight introduced accessions from The World Vegetable Center-AVRDC and as controls, two commercial varieties Mongal and Calinago, were assessed for agronomic performances at the Experimentation and Production Station of Angud dou of the National Agronomic Research Centre (CNRA) located in the South of Cote d Ivoire. The trial was arranged in a randomized block with three replications. The following parameters were determined at vegetative development stage: plant height at flowering stage, susceptibility of accessions to diseases, day to 50% flowering and day of first harvest, production duration, fruit length, fruit diameter, total number of fruits, number of fruits per plant, potential yield, net yield and fruit damage rate. Results showed that the commercial variety Mongal, with a potential yield of 15.9 and a net yield of 13.1 t ha-1, was the most productive. All the introduced accessions from AVRDC recorded the lowest potential yields from 2.2 to 9.7 t ha-1, and net yields from 1.7 to 8.6 t ha-1. In addition, accessions WVCT8, FMTT847 and WVCT13 were severely infested by bacterial wilt. The reduction of the net yield of tomato accessions resulted in the high fruit damage rates. For the future tomato breeding work, it would be appropriate to introduce into the trials bacterial diseases tolerant varieties. Moreover, some studies could be undertaken to determine the nature of the bacteria involved in the plant wilting and to find out the causal agent of the tomato plants burning at the fructification stage reducing the harvest duration.

Variety Testing

Greenhouse tomatoes are divided into early, medium and late-maturing. The days from seedling germination to the first harvest are taken into account. Tomato has a huge potential for heterosis in terms of precocity, overall yield, signs of resistance and uniformity. The preferred agricultural method is hydroponics, which allows you to grow plants without using soil, only using mineral nutrient solutions in water. The cultivation of tomato plants on the " Fitopyramida " will allow to sell their products in the periods with the highest realized prices. An experiment on variety testing of 11 tomato hybrids of different product groups that differ in precocity allowed us to select the most adapted to the conditions of the " Fitopyramida " technology, including the indeterminate beef Ruddy ball F1, cherry hybrids Elf F1 and orange-fruited cherry Magic harp F1. the determinant hybrid Captain F1 showed Good results.

A Pseudomonas sp. 102 strain, which is highly resistant to toxic effects of cadmium and has plant growth-promoting activity, can significantly increase growth parameters and biomass of tomato plants, including those observed under toxic effects of cadmium. The greatest positive effect was observed in plants transformed with the bacterial adhesin gene rapA1, the product of which is important for colonization of plant roots by bacteria. It was also shown that shoots of transgenic tomato plants accumulated the greatest amount of cadmium during inoculation with Pseudomonas sp. 102. The ability to extract high concentrations of cadmium and accumulate a large biomass under stress opens up prospects for the further use of associative interactions between tomato and Pseudomonas for phytoremediation. phytoremediation, cadmium, tomato, Pseudomonas, inoculation, agglutinins, This study was carried out using the equipment of the Biomika Centre for Collective Use of the Institute of Biochemistry and Genetics (Ufa Federal Research Centre, Russian Academy of Sciences) as part of the government task (project no. AAAA-A16-1160203500284). This study was supported by the Russian Foundation for Basic Research (project nos. 18-34-20004 and 18-34-00033) and 18-344-0033 mol_a_ved and 34-00033 mol_a).
