Yield-related agronomic traits were remarkably lower in HNIL(H143) compared with HNIL(M23). Agronomic traits were measured in HNIL(M23) and HNIL(H143) grown under natural long days in 2013. The measured traits were: main panicle length (a), number of panicles per plant (b), number of spikelets per main panicle (c), 500-grain weight (d), yield per plant (e), and seed setting rate (f). Twenty plants were used to measure each trait. Student’s t-test was used for statistical analysis (*P < 0.05, **P < 0.01, ***P < 0.001). Means and standard deviations are marked as values and vertical bars, respectively. (g) Fertile and sterile seeds from the whole plants of HNIL(M23) and HNIL(H143). Scale bar = 2 cm
