Abstract :

In this study, 20 early-ripening and 20 mediumripening soybean lines have been compared for quantitative and qualitative traits at CheginiStation of Agriculture and Natural Resources Research Center of LorestanProvince, Iran based on randomized complete block design with four replications. There was a difference in flowering among medium and early-ripening soybean lines and early-ripening soybean lines set to flower later than medium-ripening lines. Also, plant height of early-ripening linesSpry*Nemaha/8 and Spry*Savoy/2 was higher, but the vitality and un-lodging was less thanmedium-ripening lines. Early ripening line Spry*Nemaha/8 had more seed number per capsule than medium ripening lines. Also, medium-ripening line of Stressland*NMSB/3 had more thausandkernal weight than early ripening lines. Weight difference in plot and weight difference per hectare in the medium-ripeningline of Stressland*NMSB/3was more than other early-ripening lines. Medium-ripening line of Hacheston*L.16/3 hadmore protein and oil content than early ripening lines. Therefore, themedium-ripening lines had relative advantages than early ripening lines the they are recommending for region farmers soybean plantations.
