Abstract In order to innovate the lotus seed reproduction technique and promote the application of lotus true seed technology，this paper took lotus pure line variety‘Wuyuezao’as material and conducted field comparative experiment between true seed and lotus rhizome seedlings production．The results showed that the purity of lotus true seed was 97.5%，which met the requirements of field production．During early growth stage，the plant height，petiole diameter，leaf long radius and short radius，number of standing leaves of true seed were smaller or less than those of rhizome seedlings．In the middle and late growth stages，the plant height，petiole diameter，leaf long radius and short radius of these 2 reproduction methods showed nonsignificant differences，while the number of standing leaves of true seedlings was significantly more than that of rhizome seedlings．The ripening time of lotus seedlings was 21 days later than that of rhizome seedlings．The whole lotus weight of true seed was lower than that of the rhizome seedlings，but the number of rhizomes per 667 m2（813.7）was significantly higher than that of the rhizome seedlings（593.6）．Lotus root yields of these 2 reproduction patterns showed not significant difference．Moreover，comparing with conventional rhizome seedlings，the true seeds had the advantages of convenient transportation，low loss and less disease．
