Wild oat – Avena fatua L. has experienced widespread in Southern territory, Argeş County. Characters of panicles and kernels highlights how adaptation weed held in these conditions. The analyzes and measurements showed that the panicle has an average of 20 cm, formed 5 knots ramifications, with a total of 40 spikelets. The average length of the glume was 21 mm and of the kernels was 15 mm. Kernels formed in the panicle were 71, they weighted 1.5 g, and the thousand kernels of weight (TKW) was 21 g. The average length of the awns measured in the bottom portion was 11.8 mm, and 21.1 mm in the portion from the top. Correlations obtained between various characters were positive and significant. Thus, the length of panicle with total number of spikelets was the closest (r = 0.829***). Length of glume with kernel length (r = 0.366***), the length of kernel with awn length (r = 0.375***) and kernel weight/panicle with TKW (thousand kernels weight)(r = 0.334***), values were slightly lower. The present study demonstrated the wide possibilities of that weed, recently adapted into winter wheat crop.
