Abstract

Tomatoes are the most important vegetable species, both in the world and in our country. In the last decades, the breeders have obtained hundreds of varieties or hybrids for growing in open field, plastic tunnels or glasshouse. In 1975-1990 period, at Research Institute for Vegetables and Flowers Growing were drawn up breeding teams that have achieved some new valuable varieties. After 1990 year, breeding activity was decreased and only stayed at Research Station for Vegetable Buzău. Breeders of this station have obtained new outstanding varieties and hybrids with high yielding potential and good quality. For the future, it is necessary to form new teams well prepared and should more funds, with clear objectives in order to obtain new required cultivars for growers and consumers. The new cultivars have to be more resistant pathogens and adverse environmental conditions. The current climatic conditions materialized through sudden changes from day to day and even from one hour expose plants to extreme survival conditions, causing major damage, sometimes completely. The germplasm resource of S.C.D.L. Buzău currently contains in this species a number of over 700 genotypes with distinct expressiveness. Annually, it is made an evaluation of each cultivar following the purpose of achieving genetic resistant accessions.
