【摘要】：对9个经PCR检测确定为转Bt基因阳性的海岛棉品系的农艺性状和产量性状考察结果表明,外源基因Bt的导入对9个海岛棉品系的农艺性状和产量性状有不同程度的影响。1受体为K222时,Bt基因导入使得株高、始节高、始节数、有效果枝数、铃数、有效铃数差异达到极显著水平(P0.01)。当受体为XH25和XH30时,转基因品系农艺性状与对照差异无显著水平;2 9个转基因品系间株高、始节高、始节数和铃数差异达到极显著水平(P0.01),有效果枝数和有效铃数差异达到显著水平(P0.05);3 9个转基因品系的产量性状与对照差异均无显著性;4株高、始节高、始节数、果枝数、有效果枝数、铃数和有效铃数与籽棉产量呈显著相关;5两年(2014和2015)和两点(北疆和南疆)间农艺性状及产量性状差异达到显著水平。
[Abstract]:The agronomic and yield characters of 9 island cotton lines identified by PCR as BT gene positive were investigated. The introduction of exogenous gene BT had different effects on agronomic and yield characters of 9 island cotton lines. When the receptor was K222, the plant height, the number of initial nodes, the number of effective branches and the number of bolls were caused by the introduction of BT gene. The difference of effective boll number reached very significant level (P0.01). When the receptors were XH25 and XH30, there was no significant difference in agronomic characters between transgenic lines and control lines. The difference of initial node number and boll number was very significant (P 0.01), and the difference of effective branch number and effective boll number reached significant level. There was no significant difference in yield characters, initial node number and fruit branch number between the transgenic lines and the control. There were significant correlations between effective branch number, boll number and effective boll number and seed cotton yield for 52 years (2014 and 2015) and between two points (north and south Xinjiang). The difference of agronomic and yield characters was significant.
