广西区优质早熟油菜品种比较试验研究

Comparison of the High-quality and Early-maturing Rapeseed in Guangxi Province

通过2009—2010年试验,对广西引进的一批优质油菜品种进行桂北生态条件下丰产性、抗逆性及区域适应性的综合鉴定。试验采用完全随机区组排列,3次重复,小区面积13.2m2,基本苗12.0万株/hm2,试验结果测定了优质油菜产量、经济性状、生育期、抗逆性等指标。结果表明‘,史力丰’、‘丰油737’、‘浙油18’、‘云油双2号’和‘云花油9号’5个油菜品种产量较高,抗逆性较强,生育期适中,适合在广西双季稻区推广种植‘;白花09sw01h’、‘花油5号’、‘云油杂2号’和‘花油8号’4个油菜品种各方面表现较差,抗逆性较弱,可以淘汰;供试的其他品种由于产量相对较低或抗逆性较差等原因,还需作进一步试验和观察。

Comprehensively identificated a group of high-quality and early-maturing rapeseed,in Guangxi Province from 2009 to 2010,about its high-yield,resistance and regional adaptability in north region of Guangxi Province.The tests were completely random group,repeated three times.The quarter net area was 13.2 m2,the basic miller was 120000 strain/hm2.The results tested the yield of the high-yield rapeseed,its economical trait and growth stage and disease resistant.The results showed superiority of rapeseeds＇Shilifeng＇,＇Fengyou737＇,＇Zheyou18＇,＇Yunyoushuang2＇and＇Yunhuayou9＇over other rapeseeds as revealed by high yield,strong resistance and suitable for planting in double cropping rice areas in Guangxi Province,＇Baihua09sw01h＇,＇Huayou5＇,＇Yunyouza2＇and＇Huayou8＇were unsuitable for extension in Guangxi Province because of their low yield and lesser resistance,the other rapeseeds had relatively lower yield or reasonably lesser resistance,and need to be further tested.
