为进一步了解小麦生物强化育种的可行性,以山农483×川35050杂交衍生的小麦重组自交系(RIL)群体的131个株系(QM1~QM131)及其亲本为材料,连续2年在泰安和菏泽两地种植。测定该RIL群体籽粒镁、磷、硫、钾、钙等常量元素及锰、铁、铜、锌等微量元素的含量,分析了其变异系数、遗传力、相关性及环境对微量元素含量的影响。结果表明,供试材料中各被测元素的变异系数范围为7.9%~32.7%,遗传力的变化范围为29.58%~56.34%;常量元素中,镁和磷间的相关性较大,相关系数为0.440;微量元素中,锰和铜间的相关性较大,相关系数为0.454;环境对小麦微量元素含量有明显影响。高铁元素含量株系QM103、高锌元素含量株系QM105可作为育种材料。
In order to further understand the feasibility of wheat bio-enhanced breeding, 131 lines (QM1 ~ QM131) of wheat recombinant inbred line (RIL) derived from Shannon 483 × Chuan 35050 and their parents were used as material for 2 years Tai’an and Heze two places planted. The contents of trace elements such as magnesium, phosphorus, sulfur, potassium, calcium and other trace elements in the RIL population and the contents of trace elements such as manganese, iron, copper and zinc in the RIL population were determined. The effects of variation coefficient, heritability, correlation and environment on the content of trace elements . The results showed that the coefficient of variation (CV) of each element under test ranged from 7.9% to 32.7%, and the heritability ranged from 29.58% to 56.34%. Among the major elements, the correlation between magnesium and phosphorus was significant, and the correlation coefficient 0.440. Among the trace elements, the correlation between manganese and copper was relatively large, the correlation coefficient was 0.454. The environment had a significant effect on the trace element content in wheat. High-speed rail element content of the line QM103, high zinc content of the line QM105 can be used as breeding materials.
