Abstract:

Seven semi -dw arf soybean new lines are bred f rom four crosses , the yield of He 98 -1246 ,He 98 -1667 ,He 9525 -2 and ,He 98 -1459 increased 10 %more than check variety under narrow -compact planting .By comparing , the yield orders under ridge culture and narrow -compact planting are dif ferent .Under narrow-compact culture , the characters w hich af fect directly on yield per plant are seeds per plant and 100 -seedw eight , and number of pods per plant , branches per plant indirect ly af fect yield per plant .If number of seedsper plant o r 100 -seed weight is selected individually , it may increase yield per plant .Under ridge culture , thecharacters which af fect directly yield per plant is numbers of pods per plant , and number of branches and seedsper plant indi rectly affect yield per plant.Before yield selection is undertaken under narrow -compact planting ,o ther characters should be selected in F1 ～ F5 under ridge culture in dw arf and semi-dw arf soybeans breeding .
