摘　　要：利用母本729A、父本743杂交,系统选育出黄皮洋葱新品种希望之星。该品种2014年参加江苏省洋葱区域试验,2015年参加江苏省洋葱生产试验,结果表明:希望之星熟期比对照晚1~2 d,产量82500 kg/hm^2以上,比对照增产26%以上,球型指数0.85,商品性好。通过不同采收期比较发现,希望之星采收期弹性大,早收、晚收产量均比对照高。The yellow onion new variety Xiwangzhixing is bred through hybridization between 729 A（female parent） and 743（male parent） and systematic selection.Xiwangzhixing participated in the onion regional trial of Jiangsu province in 2014 and the onion production test of Jiangsu province in 2015,and the results indicated that：the maturity date of Xiwangzhixing was 1 ~ 2 days later than that of the control; the yield of this new variety was over 82500 kg/hm^2,being over 26% higher than that of the control; its spherical index was 0.85,and its commodity was good.By comparing the yield of Xiwangzhixing in different harvest periods,we found that the harvest time of this variety was flexible,and whether it was early harvested or lately harvested,its yield was higher than that of the control.
