南阳地区5个谷子品种主要农艺性状比较分析

A Comparative Analysis of the Main Agronomic Traits of Five Millet Varieties Grown in Nanyang City

为了解南阳地区谷子品种主要农艺性状特点及其相关性,本研究选取5个常规栽培谷子品种,对不同谷子品种株高、穗长、单穗质量、单穗粒质量、出谷率、千粒质量等主要农艺性状进行分析。结果表明:不同谷子品种间的产量及相关农艺性状均呈现显著性差异,出谷率和千粒质量变异系数相对较小。相关性分析表明:株高与单穗质量、穗长与出谷率之间均存在显著的负相关关系;单穗质量与单穗粒质量之间存在极显著的正相关关系。其中,小香米、G-35和豫谷18丰产潜力大,可以在南阳地区推广。

This study assessed the main agronomic traits of five millet varieties(Zhangzagu 10, Xiaoxiangmi, Jingumi, G-35, and Yugu18) commonly cultivated in Nanyang City, Henan Province, and the correlation between the traits was also analyzed. By conducting a field trial in Nanyang, various agronomic characters of millet varieties were measured, consisting of plant height, spike length, single spike mass, single grain mass, thousand-grain mass, and grain output rate. The variance analysis was performed to evaluate the differences among the five millet varieties in these traits; the correlation analysis was conducted to examine their relationship. The results showed that different varieties had significant differences in yield and agronomic traits, but the coefficients of the variations in grain output rate and thousand-grain mass were relatively small. The correlation analysis revealed that significant negative correlations existed between plant height and single spike mass, and between spike length and grain output rate, while a significant positive correlation occurred between single spike mass and single grain mass. Based on the values of the single grain mass and other agronomic traits of the five millet cultivars, Xiaoxiangmi, G-35, and Yugu18 have a higher yielding ability, so these three varieties should be promoted for large-scale production in Nanyang area.
