The present paper analyzes the descriptors of the productivity elements, the mass of one thousand grains (MMB) and the length of panicle for 15 autumn oat genotypes, created and tested under pedoclimatic area conditions from S.C.D.A. Lovrin. Between the studied genotypes there are very significant differences with reference of the length of the panicle, respectively of the one thousand grains , with a very large amplitude of variation. The biometric analysis of 14 autumn oat lines and an homologate Sorin variety, used as a control with reference to the length of panic and the one thousand grains. The data were aggregated on an agricultural year. In this case, a number of 10 plants of each studied line was studied, and the results were compared with the control variety. In terms of climatic conditions, the agricultural year 2017/2018 was a favorable year for autumn oat crops. The following lines Lv 2502, Lv 2503, Lv 2505, Lv 2510, Lv 2511, Lv 2513, Lv 2514 have been shown to have values statistically ensured as very significant, showing increases between 18.4 and 32.4% versus the witness Sorin, respectively a difference of 3.8 - 6.7 cm. With reference to MMB from the determinations analyzed, the lines Lv 2504, Lv 2513, which showed an increase of 18.5% and 14.3%, with a difference of 5.1 - 6.6g compared to the Sorin witness variety, very statistically significant values. For the two characters studied, the length of the panicle and the MMB, in the lines Lv 2504, Lv 2511, Lv 2513 recorded significant positive differences compared to the control variety. The study of the correlation between the length of panicle and the mass of one thousand grains for the 14 analyzed lines and the control variety, Sorin, show that there is a positive linear correlation between the two studied elements.
