摘要: 以15个谷子(Setaria italiea)品种为试验材料,采用相关分析和灰色关联度分析相结合的方法对与产量相关的农艺性状进行综合评价。结果表明,谷子品种的农艺性状均存在明显差异,变异系数为2.05%~22.66%;6个农艺性状与产量呈显著正相关;农艺性状对谷子产量影响的大小顺序依次为千粒重>出谷率>单穗重>生育期>穗粒重>穗长>株高>穗粗。说明谷子产量育种中要重点对具有千粒重、出谷率、单穗重性状突出的种质资源进行利用。

关键词: 谷子(Setaria italiea), 灰色相关度分析, 农艺性状, 产量

Abstract: Agronomic traits related to yield were comprehensively evaluated for 15 millet(Setaria italiea) varieties by correlation analysis and grey relation analysis. The results showed that there were significant differences in agronomic traits of millet varieties, and the coefficient of variation was 2.05%~22.66%. Six agronomic traits were significantly positively correlated with yield; the effects of agronomic traits on grain yield were 1 000-grain weight > grain yield > single panicle weight > growth period > grain weight per panicle > panicle length > plant height > panicle diameter. This indicated that the germplasm resources with prominent 1 000-grain weight, grain yield rate and single panicle weight should be utilized in millet yield breeding.

Key words: millet(Setaria italiea), grey relation analysis, agronomic trait, yield
