    摘要:

    为了探明国外苜蓿品种在吉林中西部地区的生态适应性,试验以引进的14个丹麦苜蓿品种为材料,以国内2个主栽品种做对照,采用随机区组设计,对越冬情况、秋眠习性和产草量等10个性状指标进行连续两年试验研究。结果表明,与国内苜蓿品种相比,国外苜蓿品种在越冬性和产草量等性状上没有优势,普遍表现出越冬性能差、产草量较低等特性,说明这些国外品种不能较好地适应吉林省中西部地区的气候土壤条件。但国外苜蓿品种表现出的株型直立、个体间性状一致等优良特性,可作为我国优良苜蓿品种选育材料加以利用。

    Abstract:

    In order to probe the ecological adaptability of foreign alfalfa varieties in the midwest of Jilin Province. 14 Danish alfalfa varieties were used as materials with 2 domestic varieties as the control in the experiment, and 10 characters such as overwintering, fall dormancy and forage yield were studied by randomized block design for two consecutive years. The results showed that foreign alfalfa varieties had no advantage in overwintering and forage yield compared with domestic alfalfa varieties, and showed poor overwintering and low forage yield generally, that indicated these foreign varieties could not adapt to the climate and soil conditions in the midwest of Jilin Province.However, foreign alfalfa varieties showed good characteristics such as upright plant type and consistent characters among individuals, which can be used as good alfalfa breeding materials in China.
