耐旱基因PC2300 AF1在寒地粳稻上的功能验证

Functional Verification of Drought Tolerance Gene PC2300 AFl in Japanica Rice in Cold Regions

对转入耐旱基因PC2300 AF1水稻的T1代和T2代材料进行干旱胁迫试验,验证寒地转基因水稻是否具有耐旱节水功能。结果表明:供试52份材料耐旱性不同,水稻有效穗、穗粒数、千粒质量均表现不同,与对照相比,有3份材料未结实,有20份材料产量高于对照,29份材料产量下降,不同材料间产量差异达到显著水平。

The T_1 and T_2 generations of rice with transferred PC2300 AF1 were stressed with drought to verify whether the transgenic rice in cold regions had drought resistance and water saving function.The results showed that the drought tolerance of the 52 trial transgenic materials was different,their effective spikes,grain number per spike,grain weight were different,compared with the CK.Three materials did not set seeds,The yields of 20 materials were higher than that of the CK,and those of 29 materials were lower than that of the CK. The yield difference among the materials reached a significant level.
