大豆维生素E与主要农艺性状和品质性状的相关性分析

Correlation Analysis among Vitamin E Content,Agronomic Traits and Quality Characteristics of Soybean

采用合丰25×Bayfield衍生的144份F2:6重组自交系(RIL)群体和142份黑龙江省大豆品种(系),对大豆维生素E总含量,维生素E主要组分(α-生育酚、β-生育酚和γ-生育酚)含量、农艺性状、蛋白质和脂肪含量进行了相关性分析。结果表明:在重组自交系中,株高、单株粒重与维生素E总含量呈显著正相关;在142份大豆品种(系)分析中,蛋白质和脂肪含量与维生素E总含量无明显相关性;在2组材料中均发现,α-T与γ-T,δ-T与γ-T含量呈显著或极显著正相关,δ-T与α-T含量呈负相关,α-生育酚、γ-生育酚、δ-生育酚与维生素E总含量均表现为极显著正相关。研究结果可为高维生素E大豆品种筛选提供参考依据。

One hundred and forty-four F2：6 recombinant inbred lines（RILs） derived from Hefeng 25×Bayfield and 42 local soybean germplasms in Heilongjiang province were used to analyze the correlations among total VE content,α-T content,γ-T content,δ-T content,agronomic traits,protein and oil content.In the RIL populations,plant height and grain weight per plant were significant positively correlated with total VE content.No obvious correlation were found between protein,oil and total VE content in 142 local soybean germplasms.For both tested populations,α-T and γ-T,δ-T and γ-T content had significant positive correlation,δ-T and γ-T showed negative correlation,all three sub-components showed significant positive correlation with total VE content.
