236 decreased from 92% to 60% and from 94% to 84%, respectively, but the viability was only decreased slightly from 100% to 92% for CM60 comparing to the control. For controlled deterioration treatments, soaking the seeds in distilled water prior to incubation further decreased the germination and viability of the treated seeds. The lowest germination and viability were caused by soaking the seeds in distilled water for 15 minutes and incubating at 41°C for 7 days. Soaking the seeds in distilled water for 60 minutes and then incubating at 41°C for 3 days showed the widest difference in seed germination (38.0%) and viability (17.0%) between CM60 and GC10981. Thus this treatment was considered to be an optimum one to distinguish the seed weathering of CM60 and GC10981. If ignore the fault treatment (incubator weathering at 30°C for 10 days), by comparing the means of the other 6 treatments (paired t-test), there was significant difference between CM60 and GC10981 (t 5=5.825, p=0.002 for germination and t 5=4.083, p=0.01 for viability). It was clear that the field weathering resistance of CM60 and GC10981 was significantly different. Relationship among field weathering, incubator weathering and controlled deterioration <strong>Kasetsart</strong> J. (Nat.

To confirm the possibility of using the modified controlled deterioration method for evaluating the field weathering resistance of soybean seed, field weathering (delayed harvest with water spraying) along with incubator weathering and controlled deterioration were carried out on 11 soybean varieties/lines. The seed characters and the changes in moisture content during controlled deterioration treatments are shown in Table 2. The seed moisture content of all the varieties/lines increased (3.12 to 31.1%) after soaking in distilled water for 60 minutes. The moisture content continued to increase during incubation. After soaking and incubation, the seed moisture content increased from 15.72 to 31.25% depending on the variety/line. The final moisture content of all the treated seeds varied from 23.45 to 37.95%. Different varieties absorbed water and moisture at different speeds. The seed moisture content after soaking was highly correlated to the final moisture content (r=0.951**, n=11) and the final moisture content increase (r= 0.950**, n=11). The increase in moisture content after soaking was also correlated to the final moisture content increase (r=0.952**, n=11). The treated seeds that absorbed water faster also showed the higher increases in moisture content finally. There was a significant negative correlation between the
moisture content increment after soaking and the moisture content increase after incubation (r= -0.958**, n=11). The treated seeds that absorbed more water during soaking absorbed less moisture during incubation. In contrast, the treated seeds that absorbed less water during soaking absorbed more moisture during incubation. <strong>Kasetsart</strong> J. (Nat. Sci.) 41(2) 237 The germination, viability and hardseedness of 11 soybean varieties/lines after being subjected to 3 different treatments (field weathering, incubator weathering and controlled deterioration) are shown in Table 3.
