Pectin methly esterase (PME) is an enzyme responsible for the release of methanol which is implicated to play role in causing seed deterioration. The relative intensity of PME (pectin methyl esterase) band of seed protein from seed lots differing in seed size in soybean cv. Wilis produced under field condition in dry season (August-November 2001) were compared with those in wet season (December 2001-March 2002) and were related to seed quality in order to known its possible role as the cause of seed quality differences. The relative intensity of PME band was used to estimate the content of PME. Large seed hand lower amount of PME, both in dry and wet seasons. Since lower amount and activity of PME are indicative of higher seed quality, it suggests that the low quality in small sized seed and the poor quality of seed produced in wet season may be due to higher PME content and activity in such seeds.
