Abstract:
There are few soybean varietes suitable for summer planting in Liaoning Province，and soybean germplasm introduced from higher latitude would solve this problem.The soybean variety Heihe 38，introduced from Heihe，Heilongjiang Province，was planted in Shenyang from 23th，April to 11th，July.Yield character，structure of growing stage，dynamic change of leaf area index(LAI)and biomass accumulation and equilibrium of plant organ were determined.Result showed that biological yield accumulation，LAI，and growing days were decreased with the delaying of sowing time in Shenyang.The highest yield was got when Heihe 38 was planted on 9th June.There were significant difference of seeds per plant，weight of 100-seed and yield among different sowing date treatment，a good yield was also obtained when planting on 11th July.There were significant difference on yield traits and quality between Shenyang and Heihe in the same sowing date.The results suggest that Heihe 18 can be planted in Shenyang as an relay-planting crop after harvesting spring wheat and potato.
