[Objective] This study was to reveal the differences in crude fat and glucosinolates between self pollinated seeds and naturally pollinated seeds in Brassica napus in sichuan ecological region. [Method] Near-infrared spectroscopy method (NIRS) was employed to measure the quality components in self pollinated seeds and naturally pollinated seeds of 861 shares of Brassica napus from Sichuan ecological region. And correlation analysis and regression analysis were conducted based on the experimental data via SPSS (statistics package for social science). [Result] The contents of crude fat in the self pollinated seeds were commonly a higher than that in the naturally pollinated seeds at 0.01 significant level; while the contents of glucosinolates in the self pollinated seeds and the naturally pollinated seeds were insignificantly different. Both the correlation relationship and linear regression for the crude fat between the self pollinated seeds and naturally pollinated seeds reached the significant level. The regression equations for the contents of crude fat(y1) and glucosinolates(y2) in the naturally pollinated seeds and of crude fat(x1) and glucosinolates(x2) in self pollinated seeds were respectively determined to be y1=16.844+0.614x1 and y2=-0.620+1.017x2. [Conclusion] In Brassica napus breeding, crude fat in naturally pollinated seeds should be emphatically taken into account, meanwhile concurrently considering that in self pollinated seeds; while glucosinolates in both the self pollinated seeds and the naturally pollinated seeds must be simultaneously concerned.  相似文献

1材料与方法 试验于2007年6~9月于四川省农业科学院郫县基地油菜品质测试室进行。供试材料为四川生态区861份甘蓝型油菜。采用近红外光谱分析技术(NIRS)测试861份甘蓝型油菜自交种和自然种粗脂肪、硫苷含量。仪器采用FOSS公司5000型近红外谷物分析仪,测试室温为20~25℃,空气湿度60%以下。数据一致性分析以荣廷昭介绍的方法进行,相关回归分析通过SPSS13.0完成。  相似文献

本文对861份甘蓝型油菜自交种和自然种粗脂肪含量的NIRS法测试结果进行了相关和回归分析。结果表明,以NIR法测试甘蓝型油菜自然种粗脂肪含量普遍较自交种高,自交种粗脂肪含量与自然种粗脂肪含量绝对值差异达1%显著水平。自交种和自然种粗脂肪含量的NIR法测试结果间相关关系,线性回归方程达1%显著水平,说明在已知自交种粗脂肪(x)含量测试结果的情况下,可通过回归方程y=16.844 0.614x预测自然种粗脂肪(y1)含量。  相似文献

摘 要:本文对四川生态区861份甘蓝型油菜自交种和自然种粗脂肪和硫苷含量的NIRS法测试结果进行了相关和回归分析。结果表明以NIR法测试甘蓝型油菜自然种粗脂肪含量普遍较自交种高,自交种粗脂肪含量与自然种粗脂肪含量绝对值差异达1%显著水平,自交种与自然种硫苷含量差异不显著。说明在甘蓝型油菜育种中,对粗脂肪的选择应侧重考虑自然种含量,兼顾考虑自交种含量,对硫苷的选择则可同时考虑自然种和自交种含量。自交种和自然种粗脂肪和硫苷含量的NIR法测试结果间相关关系、线性回归方程均达1%显著水平,说明在已知自交种粗脂肪( x1 )、硫苷( x2 )含量测试结果的情况下,可分别通过回归方程 y1 = 16.844 + 0.614 x1,y2 = -0.620 + 1.017x2预测自然种粗脂肪( y1)和硫苷( y2)含量。  相似文献
