Grain yield performance and yield components of cv. YK17, YK17S1, R101 and the F1 hybrid YK17S1 x R101. a Number of panicles per plant, b number of grains set on the main panicle, c thousand grain weight (g), d grain set (%), e yield per plant (g), f yield per plot (g), g plant height (cm) and h number of days to flowering. Values shown in the form mean ± SD (a, b, d, g: n = 20; c: n = 4, e: n = 6, f, h: n = 2). Asterisks (* P < 0.05; ** P < 0.01) indicate statistically significant differences between the mean performances of either cv. YK17 and YK17S1 x R101, or R101 and YK17S1 x R101, as determined by a student’s t-test
