Diameter and height of sprouts were complementarily estimated.
Principal component analysis was further employed to investigate the relationship between the agronomic variables and the cultivars and nurseries.
The parameters used to evaluate the head quality are size, shape, density color, bead size, and the attributes of stem like diameter, shape, and incidence of hollow stem.
Yield and quality characteristics were determined by genotype and environmental interaction but were not affected by photoperiod.
