*
Threshold zinc value of 20 mg/kg was set during 2013. From 2015, the optimum threshold/target content of zinc in polished rice was increased to 24 mg/kg. The same threshold values were maintained from IVT to AVT 2.
†
Yield checks: IR64/BPT5204/DRRH3.
‡
Acceptable grain quality—HRR% ≥60 with intermediate amylose content/high amylose with soft gel consistency.
