Study on Cultivated Technologys for Effective Yield of Soybean II-The Screening and Identification of Cultivars

Fifty one soybean cultivars different in plant height,were identified.They were grown on 3 rows in 1.3m wide ridges for 86.4～115 2 m 2 for each cultvar.10 accessions were screened with potential yield more than 4 500 kg/ha. The problems with the condensed planting model and cultivars selection were discussed. The cultvars resistant to lodging,high stem and bearing the density were suitable for condensed planting in this area.The breeding objective were proposed to select the cultivars of ligh stem with condensing telerance and lodging resistance.
