早春结球白菜新组合的产量及耐抽薹性鉴定

摘要

为了选育出适宜春季反季节栽培的结球白菜新品种,满足生产和市场供应需求,以北京小杂55、四季王和强势为对照,对自育的5个大白菜新组合进行了产量及耐抽薹性等性状的比较鉴定试验.结果表明:大白菜组合C-2×ye15-1和C-1×Zui-4的产量较高,分别比对照品种强势增产8.04％和4.37％,经方差分析表明,C-2×ye15-1与对照品种强势产量差异达显著水平；C-2×ye15-1和C-1×Zui-4耐抽薹性强,分别比对照品种强势、四季王和北京小杂55晚抽薹2～41d.组合C-2×ye15-1和C-1×Zui-4可作为大白菜早春反季节栽培品种在贵阳及相似地区进行推广种植.%The yield and bolting resistance of five new Chinese cabbage combinations bred by Guizhou Horticultural Institute were identified compared with Beijing Xiaoza 55, Sijiwang and Qiangshi varieties to breed out-of-season Chinese cabbage varieties for meeting production and market requirement in Spring. The results showed that the yield of C-2 ×yel5-1 and C-l×Zui-4 combinations was 8. 04% and 4. 37% higher than CK respectively, the yield of C-2×yel5-l combination was significantly higher than Qiangshi variety, the bolting time of C-2×yel5-l and C-l×Zui-4 combinations was 2~41d later than Qiangshi, Sijiwang and Beijing Xiaoza 55. C-2×yel5-l and C-l×Zui-4 combinations could be popularized in production of out-of-season Chinese cabbage in Guiyang and other similar regions.
