加拿大燕麦种质在陕西杨凌的适应性评价

The Adaptability Evaluation of Canadian Oat Germplasm

以皮燕麦品种白燕7号和科燕1号为对照,对从加拿大引进的28个燕麦种质在陕西杨凌的适应性进行评价。结果表明:在陕西杨凌地区,参试的加拿大燕麦品种在3个播期下均能够正常成熟,表现出较好的适应性,且以晚秋播产量最高;加拿大燕麦种质在生育期、株高、千粒质量等农艺性状差异明显,为合理利用这些燕麦种质提供良好的依据。

In order to evaluate the adaptability of 28 oat germplasm introduced from Canada,skin oat varieties Baiyan No.7 and Keyan No.1 were used as the control to compare with them on agronomic traits in Yangling Shaanxi province.The research results show that in the Yangling region of Shaanxi,all Canadian oat varieties were able to mature in three sowing dates,and exhibited a good adaptability,of which the late autumn sowing had the highest yield;Canadian oat germplasm have obvious difference on agronomic traits in the growth period,plant height,mass of a thousand seeds etc,offering a good basis for rational use of these oat germplasm.
