| 中文摘要: |
| 采用盆栽试验，对广东省10 个主栽花生品种进行施钙和施磷处理，利用JMP7.0 对花生的7 个主要农
艺性状进行相关分析和主成分分析。相关分析结果表明院在施磷条件下，单株产量和单株荚果数呈极显著正相关；在
施钙条件下，各性状之间的相关关系更为紧密，有多对性状的相关关系达到显著或者极显著水平。主成分分析表明院
在施磷的条件下，生长势因子为第一主成分，贡献率达43.56%;在施钙条件下，产量因子为第一主成分，贡献率达
46.22%。进行磷效率品种选择时，重点考虑的性状是主茎高、侧枝长和分枝数；进行钙效率品种筛选时，重点考虑的
性状是单株产量、百果重和百仁重。 |
| 英文摘要: |
| Through pot experiment, calcium and phosphorus were applied to the 10 main cultivated peanut varieties
of Guangdong rovince, the correlation and principal component of 7 major agronomic characters of peanut were analyzed
JMP 7.0. Correlation analysis showed that there was a significantly positive correlation between yield per plant and
number of pods per plant under phosphorus fertilizer application; in the application of calcium condition, orrelations
traits were more closely, correlations multiple pairs reached significant or extremely significant level. Principal
component analysis showed thatthe first principal component was growth potential and the contribution rate was 43.56%
under phosphorus fertilizer application; in the application of calcium conditions, as the first principal, yield factor
accounted for 46.22% contribution rate. When breeding phosphorus efficiency varieties, we should focus on main stem
height, branch length and branch number; when breeding calcium efficiency varieties, it is important to consider yield,
weight per 100 pods and weight per 100 seeds. |
