摘要

在甜菜和海甜菜的纯种品系中，对50%转基因海甜菜和抗草甘膦转基因甜菜的杂交品系进行了测试，以确定模型是否可以检测到杂交品系和纯种品系之间的任何显著差异。随着时间的推移，竞争能力是相当稳定的。95%置信限，由“bootstrap”决定;结果表明，低密度单株生物量和单位面积最大生物量在3个β系间差异不显著。根据地上生物量记录，杂交品系和甜菜品系比小甜菜品系更具竞争力。杂交种表现出最高的竞争能力，这可以用杂交活力来解释。

A method to study competitive ability of hybrids between seabeet (Beta vulgaris ssp. Maritima) and glyphosate tolerant sugarbeet (B. vulgaris ssp. Vulgaris)

A population of 50% transgenic hybrids between seabeet and a transgenic glyphosate tolerant sugarbeet was tested against pure lines of sugarbeet and seabeet to determine if a model could detect any significant differences between the hybrids and the pure lines. The competitive abilities were fairly constant over time. The 95% confidence limits, determined by the “bootstrap”; method, showed that biomass per plant at low densities and maximum biomass production per unit area were not significantly different among the three Beta lines. Based on above‐ground biomass recordings, the hybrid and sugarbeet lines were more competitive than the seabeet line. The hybrid line showed the highest competitive ability, which can be explained by hybrid vigour.
