Abstract :During two years, germinability and initial growth of seedling of nine foreign varieties and four domestic varieties were  studied. The seed is grouped by size insert ignore into journalissuearticles values(small, medium and large);, color insert ignore into journalissuearticles values(dark transitional and light color of seed coat);.  Then it was preserved and at three and fifteen months of age in the laboratory and in the field, germinability, dormant  seed and growth of shoot and radicle root were examined. In addition to the age, other factors insert ignore into journalissuearticles values(variety, size, color, period  of storage); influenced significantly insert ignore into journalissuearticles values(P≥0.05 to P≥0.00); on seed germinability and growth of seedling. Higher germinability is achieved from large seeds up to 3.6%. Depending on the seed coat color, the germinability  varied to 11%. The seed coat color has had a high impact on maintaining germinability for fifteen months. Seeds with  darker coat have also shown higher potential for storage and use in subsequent seeding periods, as determined by the  application of the aging test on seed. Significant interdependence insert ignore into journalissuearticles values(r); was obtained between the germinability test and  the growth of seedling in laboratory conditions and in field conditions. Between the germinability and the growth of the  shoot and the root, a significant interdependence was established, depending on the varieties insert ignore into journalissuearticles values(P≥0.05 to P≥0.00);.
