摘要
用 Eberhart 和 Russell 法、Francis 和 Rannerberg 法对1990年黄淮烟区13个试验点7个品种的产值及其构成因子进行稳定性分析,并提出用综合积分法来进行综合评价。结果表明,参试的7个品种中,8611在所有性状上均有上乘表现,是产值高、稳定性好的新品种;8608产值等性状表现中等,但稳定性很好;其余品种均难以超过对照品种 G-140。以产值作为主要评价性状,把产量、质量进行综合概括,可以较全面地反映出新品种的推广价值。产值的构成因子是产量和均价,它们之间相关不显著,性状间具有独立性,因果关系并非是简单的线性关系。采用无权积分方法对回归法和非回归法的4个参数进行综合评价,结果稍有差异,趋势基本一致。
The stability of flue-cured tobacco coltivars for yield,value and average price (AP) wes analysed with the methods of Eberhart & Russell and Francis & Kannerberg.A varietal sequence of stability was derived from each method.The four stability parameters,mean (x),regression coefficient (b),regression deviation (Sd) and variation coefficient (c.v%),were accumulated with the weightless method in the light of the seqence.The varietal stability formusing these methods was studied synthetically among the cultivars.The data of 7 varieties were obtained from 13 experimenfal areas in the Huang-Huai Flue-cured Tobacco Region in 1990.The cultivar 8611 had the highest yield value and better stability.The two cultivars,8608 and G-140,were second and third respectively.The stability of the yield and comprensive characters of the yieed and quelity could be used to decide the potential of the usefulness of the new cultivars.Although the yield value mainly consisted of the yield and the average price,their relations were not linear.The correlation co- efficients among three characters were not significant.The result showed that there was only minor dif- firence with the ones by the other two methods.
