The present study was conducted with the aim to evaluate sunflower hybrids under the agro - climatic conditions of Agricultural Research and Development Station (ARDS) Simnic - Craiova. A set of six foreign sunflower hybrids was sown in a randomised block design with three replications. Data were recorded on seed yield and associated traits such as plant height, head diameter, thousand seed weight and hectolitre mass. Significant differences were observed among the hybrids for seed yield and all the studied traits. Maximum seed yield was produced by hybrid Sumiko HTS (3576 kg/ha), while hybrids Subaro HTS (2700 kg/ha) and SY Bacardi CLP (2633 kg/ha) showed minimum seed yield. A moderate negative correlation, but non-significant existed between seed yield and hectolitre mass. It is concluded that the hybrid Sumiko HTS showed high productivity and was best adapted to the agro-climatic conditions of ARDS Simnic.
