Collection and data recording of popcorn from farmer's fields, local markets and government sectors were carried out in the Central plain, North and Northeast of Thailand during June, 1987 to May 1989. Twenty eight collections were planted at the National Corn and Sorghum Research Center to evaluate for their agronomic characters in dry season, 1989 (December 1988-March 1989) and rainy season(June-September, 1989) All of tested materials showed high variation in plant aspect. Seed color are white and yellow while seed shape are fan shape, rice grain shape and pearl shape. Some lines showed poor adaptability and moderately susceptible to downy mildew. Popping quality of those 28 popcorns were also studied. The result revealed that all of them showed more than 90 percent of popping. Testing for preference was also done without flavouring of seasoning. The acceptance of all tested popcorn revealed that nine lines of popcorn were better in softness, thirteen lines were better in crunchy and eight lines were less in crust. Then, Twenty two promising lines were selected and their seeds were bulked for further lines improvement next year.
