Abstract：The yield,cold resistance,disease resistance,storability and growth characteristics of new Ji-tui onion variety Laicong 1 were studied in this paper.The results showed that the yield of Laicong 1 was 4 350.60 kg per 666.7m2 ,which increased by 105.28% than Laiwu Jitui onion.It had stronger cold resist-ance,disease resistance and storability than those of Laiwu Jitui onion and Zhangqiu onion,which was suit-able for planting in plain and hilly area.The plant was 105 ~110 cm in height,and the length of scallion stalk was 30 ~40 cm with the expansion coefficient of 1.20 ~1.40.The single plant weight was 0.25 ~0.30 kg. September was the key period for yield formation,and October was the key period for the formation of typical external features and pseudostem yield.In October,the plant height and weight increased slowly and tended to be stable,while the pseudostem weight increased consistently.With the ratio of pseudostem weight to plant weight and the expansion coefficient increased obviously,the pseudostem became typical chicken -leg shape after the middle of October.
