福建花生产量与主要农艺性状之间的灰色关联度分析

Analysis of Gray Correlation between Yield and Major Agronomic Traits of Peanut in Fujian Province

采用灰色关联度分析法研究了11个花生品种的产量与主要农艺性状之间的关系。结果表明:影响花生产量的主要农艺性状的排列顺序为:主茎高>第一对侧枝长>单株饱果数>百果重>单株秕果数>单株分枝数>单株结果枝数>生育期。因此主茎高对花生产量的影响最大,生育期对花生产量的影响最小。

The relationship between the yield and major agronomic traits of 11 peanut varieties was analyzed with gray correlation analysis.The results indicated that the major agronomic traits which had influences on the yield had the following order： main stem height the first pair of lateral branch length plump pod number per plant 100-pod weight un-plump pod number per plant branch number per plant bearing branch number per plant growth period.Therefore the main stem height had the greatest influence on the yield of peanut,while the growth period had the least influence on the yield.
