Ampelographic description
Identification signs include:
- the tip of the young shoot is closed and has a medium to heavy coat of flat-lying hairs,
- the young leaves are green,
- the shoot has an absence of flat-lying and upright hairs,
- adult leaves are wedge-shaped with a very open petiolar sinus, very long teeth compared to width with one concave and one convex side, three terminal teeth on the central main vein and two principle adjacent lateral veins which are longer and more developed. The underside has a medium to heavy coat of upright hairs,
- flowers are female,

Resistance to soil parasites
The degree of tolerance of 1616 C to radicicolae phylloxera is high with good resistance to the nematodes Meloidogyne arenaria and Meloidogyne incognita.
Adapt to environment
The degree of tolerance of 1616c to chlorosis is low to medium and it resists only 11% to active limestone. Its adaptation to humidity is fairly good in addition to its tolerance to chlorides. 1616 C is well-adapted to sandy clay soils.
Interaction with grafts and production objectives
The vigor of 1616 C is low. This root stock produces good quality products.
Aptitudes for plant propagation
1616 C is a moderate wood producer (40 000 to 60 000 m/ha) and has a good capacity for propagation by cuttings and grafting. Wiuth vigorous root stocks, the roll at the graft can become quite large.
Resistance to aerial parasites
1616 C has good tolerance to gallicolae phylloxera and good resistance to downy mildew and anthracnosis.
Clonal selection in France
The 2 approved 1616 C clones carry the numbers 98 and 763.
