Few studies have been considered the role of seed coat characteristics on resistance to preharvest deterioration. The objective of the study was to relate soybean seed coat characteristics with resistance to weathering. Eleven soybean genotypes were grown on November 2000 at the Agriculture Faculty Experimental Farm Bengkulu in a randomized complete block with three replications and subjected to (1) incubator weathering, (2) field weathering, (3) wet-bag weathering, and (4) unweathered seed as a control. Across black and yellow seeded genotypes, soybean with black seed coat showed less susceptible to all weathering treatments than that with yellow seed coat. Germination of all black seeded genotypes following incubator weathering was above 50% and remained above 50% after accelerated aging except for Merapi. Not all yellow seeded genotypes were susceptible to incubator weathering. There was a yellow seeded genotype such as Lumajang Brewok showing resistant to this stress. Germination, germination after accelerated aging and electrical conductivity following all weathering stresses were significantly correlated with lignin content in the seed coat except for germination following field weathering. The correlation coeffcients [r] ranged from 0.07 to 0.89 for germination, from 0.40 to 0.77 for germination after accelerated aging, and from -0.66 to 0.82 for electrical conductivity. Overall, genotypic differences in resistance to preharvest deterioration were influenced by seed coat color and seed coat lignin content.
