Abstract: Soybean and other legumes have hard seed (Rolston, 1978). Hard seed coat protect seeds from harsh environment and this trait gives special agronomic character for seeds. Hardness also protect from seed decay (Taylor, 1997). However, hardness is sometimes undesirable, Hence, breeding program need to be establish to maintain the lines to get good permeability and strong seed coat. Among the two soybean cultivars one is vegetable type Karune and another grain type William 82. In the study Karune has more permeability of water as compared to William 82. Crinkled formation in the seed coat showed of Karune is the indication of the primary site of hydration. The SEM study showed that the seed permeability of water due th small cuticular cracks present on the seed surface of vegetable type soybean, which was examined by the SEM. The size of micropyle, hilum, raphe, depression size near hilum and Hilar fissure in Karune mean was recorded 268.71µM, 1165.47µM, 120.34µM, 51.09 µM and 45.04 µM respectively.
