13个糜子品种高产稳产性分析

Analysis of the High and Stable Yield of 13 Millet Varieties

为选育出稳产、高产的糜子新品种,运用高稳性系数法(HSC)分析了13个糜子品种的高产稳产性,并进行了参试品种的平均产量、标准差、变异系数和高稳系数的相关分析。结果表明:粘丰7号和雁黍11是聚合了高产稳产基因的优良糜子品种;各参试品种的产量高稳系数与单产呈极显著正相关,与变异系数和标准差呈负相关。HSC是一种比较理想的衡量糜子品种高产稳产性的综合指标,计算简便,可用性强。

In order to breed new millet varieties with stable and high yield,13 millet varieties were analyzed by high stability coefficient method,and the correlation analysis of average yield,standard deviation,coefficient of variation and high stability coefficient of the tested varieties was carried out.The results showed that,Nianfeng No.7 and Yanshu 11 were excellent millet varieties with high and stable yield genes;the high and stable yield coefficient of each tested variety was significantly positively correlated with the yield per unit area,and negatively correlated with the coefficient of variation and standard deviation.HSC is an ideal comprehensive index to measure the high and stable yield of millet varieties.It is easy to calculate and has strong usability.
