甘蓝型油菜新品种(组合)抗裂角性筛选试验
|
摘要
为了研究最新育成适宜长江流域生态区的油菜品种(组合)对机械化收获的适应性,以改进后的随机碰撞法对长江上游区域试验的22个甘蓝型油菜(Brassica napus L.)品种(组合)进行了抗裂角性鉴定。结果表明,抗裂角指数为0.05~0.76,对照品种蓉油18的抗裂角指数为0.16,极易裂;对照品种中双11(常规品种)的抗裂角指数为0.61,为中抗。鉴定出平均抗裂角指数较高的新品种(组合)7个,分别是邡牌油555、万油26、绵油21、庆油8号、内油835、黔油31、德新油97。对抗裂角指数较高的7个新品种(组合)的产量、抗倒伏、抗病等性状进一步进行了分析,筛选出了具有适宜机械化收获性状的庆油8号、内油835、黔油31、万油26,对这4个品种(组合)的产量等性状还有待进一步研究。
In order to understand the suitability of newly developed lines in the ecological area of the Yangtze river basin for machine harvesting,22 hybrids or lines of Brassica napus involved in the national regional trials of the upper Yangtze river reaches were assessed for pod shatter resistance using improved random impact test method. The results showed that pod shatter resistant index ranged from 0.05-0.76. The index of control variety Rongyou18 was 0.16,with a very low pod shatter resistance. The index of control variety Zhongshuang 11 was 0.61,with an intermediate resistance. 7 new hybrids or lines with higher average pod shatter resistance index were identified,including Fngpaiyou 555,Wanyou 26,Mianyou 21,Qingyou 8,Neiyou 835,Qianyou 31 and Dexinyou 97. Based on further analysis of other important agronomic traits of the 7 hybrids or lines with relatively high pod shatter resistance,4 hybrids,including Wanyou 26,Qingyou 8,Neiyou 835 and Qianyou 31,could be used for machine harvesting cultivation. The yield and other traits of these 4 varieties should be further evaluated.
