Conteúdo: | An evaluation of 4582 entries of soybean germplasm from southern China to soybean agromyzid fly was carried out. The standart-variety grade system, with the number of maggots, pupae and pupae cases in stem as indicator and the 10 high-resistant and 10 high-susceptible entries screened out from this study as checks, was suggested for the evaluation of resistance to the pest. There was no immune material found, while among germplasm from tne Southeast  Area and Lower Yangtze Valley existed some entries with relative high resistance. This kind of resistance apperead to be inheritable, but only of low heritability value. In addition, the resistance was found to be related with growth period traits, number of branches, leaf color, and density and form of pubescence, but independent of lower color, seed coat color, and color, length, and thickness of pubescence.
