摘　　要：为筛选适宜河南地区种植的早熟大白菜品种,选取5个品系进行2年品种比较试验。结果表明,‘郑白65’大白菜生育期63.0 d,熟性最早,软腐病和霜霉病较轻,田间表现抗病毒病,667 m^2净菜产量6 979.50 kg,可于国庆节前上市,经济效益高,是适合河南省大部分地区夏、秋栽培的早熟大白菜品种。新品系‘15t43×11v39’大白菜熟性也较早,对霜霉病和软腐病抗病性强,667 m^2净菜产量5 984.28 kg,有待进一步提纯推广。In order to screen the suitable early-maturing Chinese cabbage for Henan area, five cultivars were carried out for the comparative test of two years. The results showed that the maturity of ＇Zhengbai 65＇ was the earliest. Its soft rot and downy mildew was slighter, and it was resistant to virus. Its yield and economic benefit were high, it was suitable for cultiva- tion as summer and autumn early-maturing Chinese cabbage cultivars planting in Henan province. The maturity of the new line ＇ 15×43x 1 1v39＇ was also early, it was resistant to soft rot and downy mildew, and had high yield and economic benefits.
