转基因小麦“中间试验”与农艺性状评价

Field Trial and Agronomic Performance of Transgenic Wheat in Hubei

在湖北武汉对3个转基因小麦品系连续2次进行了"中间试验"。结果表明:在田间栽培条件下,转基因小麦植株个体生长发育正常,但转基因小麦主要农艺性状与对照间存在差异;特别是小区产量与本地小麦品种之间存在极显著差异;转基因小麦品系与其受体品系之间千粒重和小区产量上存在显著差异或极显著差异。组织化学和SDS-PAGE检测结果表明,外源基因能够稳定遗传,功能得到正确表达。

Three transgenic wheat lines have been evaluated under field conditions during 2 years continuously, together with 4 non-transgenic lines of wheat. Two of the non-transgenic lines are donor plants of the transgenic lines and the other two are local region cultivars used as control materials. The plant growth and development of all transgenic lines were normal under the conditions tested. But their morphological and major agronomic traits were different from the donor plants, especially when comparing with 2 local cultivars. In the yield and 1000 grains weight, there was difference of major agronomic traits between transgenic lines and its donor lines. Results of the histochemical and SDS-PAGE analysis showed that the target genes were stably inherited.
