25个谷子品种的适应性综合评价
Comprehensive Evaluation of Adaptability of 25 Millet Varieties
摘要
Abstract
In order to screen the millet varieties suitable for planting in Xing'an League,and to provide reference for the in-troduction and breeding of new millet varieties for this area,25 introduced millet varieties from different producing areas were used as materials.The six characters of the tested varieties were evaluated comprehensively by means of correlation a-nalysis,principal component analysis and cluster analysis.The results showed that the coefficient of variation of six charac-ters was yield＞grain quality per ear＞ear quality＞ear length＞plant height＞growth period,and there was a significant positive correlation between ear quality,grain quality per ear,ear length and yield,and a negative correlation between plant height,growth period and yield.25 millet varieties can be clustered into 4 groups at Euclidean distance of 10.Group Ⅰ has higher plant,shorter ear,smaller spike and grain weight per ear,lower yield and can not mature normally.Group Ⅱ has moderate plant,longer ear,higher grain quality per ear,higher yield and shorter growth period.The plant of group Ⅲ is short,the ear is short,the weight of single ear and grain per ear is small,the yield is slightly lower,the growth period is lon-ger,the plant of group IV is higher,the ear is longer,the quality of single ear and grain per ear is medium,the yield is me-dium,and the growth period is moderate.According to the comprehensive evaluation combined with the above analysis methods,the varieties suitable for planting in this area are Nenxuan 18,Nenxuan 15,Zhangzagu 13,Chaogu 58,Yugu 35 and so on.关键词
