Values represent the means ± SD. Significant differences were determined using independent samples t-test; * and ** indicate significant differences at 0.05 and 0.01 probability levels, respectively. PH–plant height; EPP–the effective panicle number per plant; PL–panicle length; GL–grain length; GW–grain width; TGP–the total grain number per panicle; FGP–the filled grain number per panicle; SSR–seed setting rate; TGW–1000-grain weight
