重庆地区饲料油菜的品比试验与分析

Variety Comparative Experiment and Analysis of Forage Rape in Chongqing

本试验将6个饲用油菜品种进行生态适应性研究及品比试验,结果表明,外引1号品种生育期与本地油菜品种基本一致,外引2号在中海拔地区抽苔期,开花期、结荚期晚于外引1号品种,在低海拔地区不能开花结种;2012年至2014年的品比试验中产量最高的是外引1号,达到35.41~37.43kg/6m2,植株高度最高的是本地1号、本地2号、外引1号,3个品种之间植株高度差异不显著,但均极显著高于其余品种。

In the experiment, the ecological adaptability and variety comparative test for 6 forage rape varieties was carried out. The results showed the growth period of the imported No.1 was consistent with the local rape varieties; while, the bolting stage, flowering stage and pod-setting stage for the imported No.2 was latter than NoA, and, at lower altitude area, the imported No.2 could not flower and fruit. The variety comparative test between 2012-2014 showed the fresh forage yield of the No.l was the highest, reaching 35.41-37.43kg/6m^2, and the local No.l, local No.2 and brassica napus No.1 had the highest plant height, with insignificant difference.
