Abstract:

To clarify the effects of soybean staygreen syndrome on the yield.Different treatments were set up for the main hazard factors that cause soybean staygreen syndrome disease,the resistance of 65 soybean varieties was screened and identified,and the synergistic effect of different hazard factors was analyzed. The results showed that the resistance of different soybean varieties to soybean hazard factors was different,and the number of T2 treated soybean staygreen syndrome sensitive varieties was the smallest,with 53,accounting for 81.54%. The number of soybean staygreen syndrome sensitive varieties of T4 was the largest,with 58,accounting for 89.23% of the total. Compared to the changing range of the control,the average rate of soybean staygreen syndrome with T4 and T5 composite hazard factors (263.87%—281.57%)was larger than that of individual hazard factors (117.82%—151.58%). The effects of treatment of different hazard factors on the main agronomic traits of soybean have reached a significant level. Compared with the control,among the seven major agronomic traits,the 5 treatments of the node numbers of main stem had the smallest change range,with an average of decreasing range 7.71%,and the number of staygreen syndrome pods per plant had the largest change range,with an average of amplification 83.52%. Among the three yield related traits,the 5 treatments with 100 seed weight had the smallest loss rate compared with the control,with an average of decreasing range 8.70%,and the 5 treatments with seed weight per plant had the largest loss rate with an average of decreasing range 52.51%. In short,the results revealed that the effects of treatment of different hazard factors on the yield and main agronomic traits of soybean have reached a significant level,and the seed weight per plant had the largest change compared with the control.
