摘　　要：利用2002年至2004年云南杂交油菜新组合区域试验资料,对6个组合在云南9个不同生态区的产量及产量构成因素、组合与试点的互作效应等进行了分析,结果表明:2000F100D、99F089D等5个组合的平均产量与对照品种云油杂1号和花油3号之间的差异达显著或极显著水平,说明云南在进一步提高杂交油菜产量上取得了显著进展;5个组合中,以99F089D的丰产性、适应性和稳产性最好;2000F100D的产量优势极显著,适应性好,这2个组合可在其适宜区域扩大示范。Using the data from regional test of Yunnan new hybrid rape combinations during 2002 - 2004, the yield and yield components, interaction effects among 9 sites and 6 combinations were analyzed to evaluate the adaptability, stability and yield performance. Results indicated that 5 out of 6 tested combinations were significantly higher than the check varieties Yunyouzal and Huayou3 in average yield, suggesting that obvious advances had achieved in further raising yield heteresis of hybrid rape in Yunnan. And 99F089D had the best adaptability, stability and good yield performance and 2000F100D was outstanding in yield and adaptability,so both combinations could be further demonstrated in their suitable area.
