Performance of three homozygous transgenic lines in the T₃ generation under nature conditions. a–c Cross morphologies (a) flag leaf morphologies (b) panicle morphologies (c) of the lines with NAL1 or GNP1, the lines carrying both NAL1 and GNP1, and Nongken58 (transgenic control). (+) indicate transgene-positive. d–f Effective panicle number (d) flag leaf area (e) grain number per panicle (f) are compared the lines with either NAL1 or GNP1 with the lines carrying both NAL1. Error bars indicate SD. Letters on histograms (a, b, and c) are ranked by Duncan’s test at P < 0.05. Scale bars represent 10 cm (a) or 2 cm (b)
