The results of the seed development and maturation studies in ambrette revealed that the pods and seeds attained physiological maturity on 35 days after anthesis as evidenced by the maximum dry weight of pod (2.694 g) and seed (12.63 mg) combined with minimum moisture content of pod (23.45%) and seed (21.64%). The change in colour of pod and seed from green to brown could be considered as a visible index of maturity. The seed quality parameters viz., germination (41%), 100 seed weight (1.468 g), seedling length (16.3 cm) and drymatter (8.0 mg) and vigour index (668) were also maximum at 35 days after anthesis.
