中文摘要:
      用双因素方差分析、相关性分析和主成分分析法对4 个花生品种在覆膜施肥、覆膜不施肥、不覆 膜施肥3 个处理下的14 个农艺性状进行分析。结果表明:(1)在覆膜条件下,施肥对4 个花生品种的7 个农 艺性状有显著影响,其中花育39 的百仁重显著低于其他3 个品种;在都施肥全生育期除草条件下,覆膜对4 个花生品种的14 个农艺性状没有显著性影响,但天府28 的出仁率显著低于其他3 个品种。(2)相关性分析 结果表明,3 个处理下,与花生的主茎高和百仁重显著相关的农艺性状数量最多。(3)主成分分析结果表明, 3 个处理下的前2 个主成分的累计贡献率分别为86.39%、91.14%、85.31%,且不同处理下的主成分存在差异, 但是主茎高、总果数和百仁重的载荷值均较高。综合分析可知,在今后的花生选育工作中要重点关注花生主茎 高和百仁重。
英文摘要:
      Forteen agronomic characters of peanut were analyzed using the double factor variance analysis, correlation analysis and principal component analysis under film mulching cultivation with fertilization,film mulching cultivation without fertilization and open cultivation with fertilization conditions. The result showed that:(1)Under film mulching cultivation,fertilization treatment had significant influence on 7 agronomic characters of 4 peanut cultivars, and the 100-kernel weight of Huayu 39 was significantly lower than that of other 3 peanut cultivars. Film mulching treatment had no significant influence on 14 agronomic characters of 4 peanut cultivars under fertilization and weeding, but the kernel percentage of Tianfu 28 was lower than that of other 3 peanut cultivars.(2)Correlation analysis indicated that the number of agronomic characters correlated with plant height and 100- kernel weight under the 3 treatments was the most.(3)Principal component analysis showed that the cumulative contribution rate of the 2 principal components under the 3 treatments was 86.39%,91.14%and 85.31%,respectively. There were differences on the 2 principal components under the 3 treatments,however,all of load value of plant height,pod number per plant and 100- kernel weight were high. Above all,more attention should be paid on the plant height and 100- kernel weight in future of peanut breeding.
