优质杂交油菜撒播试验组合比较研究

Comparison on Broadcast Test Combinations of High-quality Hybrid Rape

[目的]筛选可参加国家区试高密度试验组的优质油菜组合。[方法]采用随机区组试验设计,对6种优质油菜新品种(组合)进行了撒播试验。[结果]H0903产量最高,平均单产为2 002.65 kg/hm2,比油研10号高出19.38%,综合性状均较好,适合密植。H0904平均单产为1 715.10 kg/hm2,居参试品种第2位,可升级进入多点区域试验鉴定。H0901与油研10号相比略有减产,建议继续鉴定后作取舍;H0905和H0902与油研10号相比减产幅度较大,建议淘汰。[结论]H0903可参加国家区试高密度试验组。

[Objective] The aim was to screen out high-quality rape combinations for national test group of high-density.[Method] 6 kinds of high-quality combinations were made a broadcast test with random block experimental design.[Result] H0903 had the highest yield.Its average yield was 2 002.65 kg/hm2,which was 19.38% more than Youyan 10.Furthermore its comprehensive characters were better,so it was suitable for close-planting.The average yield of H0904 was 1 715.10 kg/hm2 which took the second place,so H0904 could participate in multi-point regional test appraisal.Compared with Youyan 10,H0901 had a reduction of output slightly,so it should be screened sequentially.Compared with Youyan 10,H0905 and H0902 had a larger reduction of output,so they should be eliminated.[Conclusion] H0903 could participate in the national test group of high-density.
