MATERIALS AND METHODS Biological material studied consisted of 15 varieties of winter wheat: Flmura 85, Lovrin 34, Alex, Simnic, Albota, Boema, Crina, Delabrad, Dor, Faur, Glosa, Ciprian, Briana, Exotic, Capo. The research was place in CCDCPN Dabuleni, during 2010-2012. Were made following observations and measurements: - determined of protein: Perten method; - determined of moisture-Perten method; - determined of wet gluten-Perten method; - determined of sedimentation Zeleny index Perten method; - determined the MMB; - determined MH; - production (kg/ha). The experimental results were processed by variance analysis and calculation of correlation coefficients (Saulescu, 1967). RESULTS AND DISCUSSIONS A complex area, in which we must improve the knowledge and understanding in order to take immediate and correct view to ensuring to obtain agricultural productions high performance it represents major climate change of our century. Drought remains still an important abiotic stress factor that threatens agricultural production in many parts of the country, particularly in the south, the water becoming a scarce resource which requires economic and environmental management, conducted with great care. Climate change in recent years, have highlighted the clear trend of global warming and the intensification and expansion of droughts, with negative implications for crop plants. During the experiment included three different years in terms of water and temperature regime: 2010-rainy year, 2011-dry year and 2012 -very dry year (Table 1). Table 1. Abiotic stress factors manifested in the vegetation period of winter wheat CCDCPN Dabuleni (2010-2012) Stress factors 2010 2011 2012 Number of days with maximum temperature> 30 C 0 during May-June 13 11 25 Number of days with atmospheric humidity < 30% during May-June 3 17 20 S temperatures (C 0 ) 4048 3942 4612 The normal (C 0 ) 4099 4088 4136 Differences ± the normal (C 0 ) -51 -146 + 476 S rainfall (mm) 710 376 383.51 The normal (mm) 548 545 542.9 Differences ± the normal (mm) +162 -169 -159.4 Characterization years Rainy Dry Very dry Table 2.

The year 2010 was characterized as a wet year, marking a higher amount of rainfall, with 162 mm of multiannual amount and frequency of days with temperatures >30 o C and atmospheric humidity 30 o C(11 days), relative humidity 30 o C and 20 days with relative humidity
