    Vegetable soybean is an important bean vegetable in China. Its grain type trait is a comprehensive indicator of seed size and fullness，and it is also a key factor affecting soybean commodity properties and sowing quality. In this study，78 vegetable soybean varieties with local characteristics were collected from Hubei，Henan and other regions. Through field and indoor experiments，the grain traits such as 100-grain weight，seed length，seed width and seed coat color of this group were observed. The statistical analysis was carried out. The results showed that the 100-grain weight of the 78 populations was highest up to 37. 10 g，the minimum was 4. 95 g ，and the average was 19. 46 g. The seed length was 0. 67 to 1. 22 cm，with a mean of 0. 87 cm. The maximum grain width was 0. 9 cm，the minimum was 0. 47 cm，the average width was 0. 70 cm. The aspect ratio was between 1. 05 ～ 1. 50，and the average value was 1. 2. In terms of the color of the seed coat of the varieties，the yellow was close to half，and the rest were less. Finally，based on the 100-grain weight，six oversized grain germplasms and one small-grain germplasm were screened to provide genetic material for further genetic improvement of vegetable soybean.

    The responses of vegetable peas on neutral salt NaCl and alkaline salt NaHCO3 stresses during seed germination with gradient concentrations of NaCl and NaHCO3 solution were studied in this paper. The results showed that the seed germination and seedling growth of vegetable pea were inhibited while the concentration of NaHCO3 solution reached 25 mmol/L；moreover，the seeds could not germinate when the concentration of NaHCO3 solution was 200 mmol/L；however，the coefficient of seed vigor was increasing，and the growths of pea seedling main root and bud were promoted while the concentration of NaCl solution was 25 mmol/L，the seed germination and seedling growth of vegetable pea were not inhibited until the concentration of NaCl solution over 100 mmol/L. Therefore，the alkaline salt NaHCO3 is more obvious than the neutral salt NaCl to inhibit the vegetable pea germination；the NaHCO3 has more obvious effect on vegetable pea cultivation when it accumulates in soil.
