摘要：

对‘甘引1号’黑麦（Secale cereale L.‘ganyin No1’）种质的8个农艺性状与鲜草产量的关系进行分析。结果表明：分蘖数、茎叶比和穗重与产量表现为极显著正相关，株高和穗长与产量的相关性也达到显著水平；株高、分蘖数、茎叶比、和穗重4个农艺性状对产量形成的贡献最大，是构成产量的主要因素。

Abstract:

The fresh forage yield and eight agronomic traits of Secale cereale L.‘ganyin No1’ accessions were studied by multiple analyses. The results showed that the forage yield had an extremely significant correlation with tiller number, stem/leaf, spike weight and plant height. Meanwhile, multiple analyses showed that four agronomic traits including plant height, tiller number, stem/leaf and spike weight are the main factors that resulted forage yield variations of. Secale cereale L.‘ganyin No1’.

Key words: Secale cereale L.‘ganyin No1’, Agronomic traits, Correlation analysis, Partial correlation analysis, Path analysis, Principal components analysis
