Estimates of the genetic parameters of the three phytochemicals in a 7×7 half diallel.

ns: non-significant, **: significant at P≤0.01 level, : broad-sense heritability (%), : narrow-sense heritability (%), GR: genetic ratio, PH: plant height (cm), AGP: AG percentage per plant (%), AGC: AG content per plant (g), AGY: AG yield per hectare (kg/ha), NAGP: NAG percentage per plant (%), NAGC: NAG content per plant (g), NAGY: NAG yield per hectare (kg/ha), DDAGP: DDAG percentage per plant (%), DDAGC: DDAG content per plant (g), DDAGY: DDAG yield per hectare (kg/ha). AGY, NAGY and DDAGY possessed similar heritability values with AGC, NAGC and DDAGC, respectively. Hence, these components are not presented in this table.
