丹麦苜蓿在公主岭地区表现及农艺性状间相关分析

Performance of Denmark alfalfa varieties in Gongzhuling area and the analysis of agronomic traits correlation

为了探讨国外苜蓿品种在吉林中部地区的表现及苜蓿农艺性状间关系,试验测定了16个丹麦苜蓿品种与2个国内品种的鲜草产量、秋眠性、花期等农艺性状。结果表明:丹麦苜蓿品种与国内苜蓿品种相比不存在生产性能优势;农艺性状间存在一定的相关性,其中鲜草产量与花期早晚、田间密度密切相关,秋眠性与花期早晚、抗倒伏能力密切相关。

To investigate the performance of the oversea alfalfa varieties in the middle area of Jilin province and to analyze the correlation of agro- nomic traits between alfalfa varieties, yield, autumnal dormancy, bloom time etc. agronomic traits of 16 Denmark and 2 domestic alfalfa varie- ties were detected. Result showed that the Danish alfalfa varieties did not have the advantages of production performance while compared with domestic alfalfa varieties; but there was certain correlation among agronomic traits. Specifically, the fresh yield and flowering time, field density was closely related, and the autumn dormancy was closely related to the flowering time and the lodging resistance.
