Table 2.

Yield components and grain yield of LSE1, wild-type and the original cultivar Nipponbare grown under field conditions.

	Panicle number per plant	Spikelet number per panicle	Percentage of (g 1000 grains-1)	Grain weight	Grain yield (g m-2)
Wild-type	9.5 ± 0.2 (100)	105.8 ± 3.0 (100)	74.8 ± 1.6 (100)	26.5 ± 0.3 (100)	444.1 ± 8.9 (100)
LSE1	8.7 ± 0.3* (91)	101.1 ± 4.0 (96)	64.1 ± 2.0** (86)	25.1 ± 0.2** (95)	313.2 ± 21.2** (71)
Nipponbare	9.0 ± 0.3 (95)	115.8 ± 4.8 (109)	78.9 ± 0.8 (105)	26.7 ± 0.1 (101)	488.9 ± 31.0 (110)

Data were obtained in the field trial, conducted at The University of Tokyo in 2010. The numbers in parentheses indicate relative values when the mean value in the wild-type is 100. Data represent the mean values ± SE (n = 12). Asterisks indicate the significance of the mean values of LSE1 plants or Nipponbare plants from that of wild-type plants by t-test at *p < 0.05 and **p < 0.01. Note that no significant differences were observed in yield components and grain yield between wild-type plants and the original cultivar Nipponbare, indicating that these two lines were similar with regard to growth and productivity in paddy fields.
