Abstract: An experiment was conducted at Agronomy Division, Bangladesh Jute Research Institute, Dhaka in 1997 and 1998 with white jute (Corchorus capsularis L.) varieties CVL-1 and CVE-3 to study the seed filling period and attainment of physiological maturity of white jute seeds and its effect on seed quality attributes. In white jute, physiological maturity of seed attains at 60 days after anthesis irrespective of variety and there was significant positive correlation between seed filling period and seed quality attributes. Seed filling period (SFP) and effective seed filling period (ESFP) were 36 and 21.2 days in both the varieties respectively. The single seed filling rate (SSFR) was 0.08 mg/seed/day and total seed sink filling rate (TSSFR) was 10.25 kg/ha/day in both the varieties also. A significant positive correlation among the seed attributes with the seedling dry weight, vigour and emergence percentage in both CVL-1 and CVE-3 indicated that germination percentage and emergence percentage influenced crop establishment.
