Grain yield with N fertilizer (YN, a–c), grain yield without N fertilizer (Y0, d–f), and increase in grain yield with N fertilizer (∆YN, g–i) of hybrid and inbred rice cultivars grown in Xingyi, Guizhou Province, China in 2012 (a, d and g), 2013 (b, e and h) and 2014 (c, f and i). LYPJ (Liangyoupeijiu), YLY1 (Y-liangyou 1), LY9348 (Luoyou 9348) and WY308 (Wuyou 308) are hybrid rice cultivars. HHZ (Huanghuazhan) and YXYZ (Yuxiangyouzhan) are inbred rice cultivars. Data in a–c and g–i are the means across two N fertilizer rates. Data points are means and standard deviations of three replications (d–f) or six replications (a–c and g–i). Data points marked with the same letters are not significantly different at the 0.05 probability level according to LSD test
