Phenology
Bud burst: 2 days after Chasselas.
Grape maturity: period II, 2 weeks after Chasselas.
Suitability for cultivation and agronomic production
This variety displays semi horizontal growth and has relatively not fertile vine eyes at base. It must be pruned moderately long or possibly short-pruned. Melon B is well adapted to clay-siliceous terroirs and to fairly cool regions.
Sensitivity to diseases and pests
Melon B is fairly sensitive to downy mildew and very sensitive to grey rot. It is, on the other hand, not very susceptible to powdery mildew and eutypiosis.
Technological potential
Grape clusters are small to moderate size with small berries. Melon B produces balanced, fresh, light, pleasant with discreet aroma wine. White wine produced has good capacity for ageing on lees.
Clonal selection in France
The 12 approved Melon B clones carry the numbers 177, 227, 228, 229, 230, 231, 232, 441, 442, 443,1057 and 1120. A conservatory was set up  in 1993 in the Nantes region vineyards and includes close to 300 clones.
