Comparison of Yield in Korean Small Seed Soybean Cultivars with Main Stem and Branch Production

摘要: showed the highest value by 7.6, and followed that of 3,~, 1=: over 4," branch in this order. The seed yield varied from 168 tb 289g' m~' average all soybean cultivars w~s 225g m~'. relation beiween th~ days'of flOwering to maturing date was high significant difference (r=0.575, p<0.01) there ~vas a significance (r= 0.781, between days planting flowering date. level higher period vegetative s~age than Period reproductive stage small soybeans.
